HP 636 Battery www.all-laptopbattery.com

Performance is good, though, thanks to a Haswell Core i5 processor that runs at a healthy 2.6GHz, along with 8GB of memory and a 500GB hybrid drive. That combination manages solid scores of 2608 and 3026 points in the Home and Work suites in PCMark 8, and matches the performance of many of its more expensive rivals.The Prestige weighs 2.2kg, which is a little heavy to carry around in a backpack, but it’s actually below average for a 15-inch laptop that includes a built-in DVD drive. The battery also managed just four minutes short of five hours when running the intensive PCMark 8 benchtests, so it’ll earn its keep if you do need to take it away from the office occasionally.Back in the old days providing your employees with corporate computer equipment was an expensive business. When I was 19 I was the university holidays PC guy in an office full of RPG III developers; the fact that they thought their System/38 with its 5250 terminals was a pretty neat piece of kit was the only reason they didn't envy the spanking new IBM PS/2 Model 80 under my desk.Over the past 20 years I have had a succession of expensive company computers: a Macintosh LC that had the same 68020 processor as the Sun-3 kit of which I was sysadmin at the time; the Mac IIfx that replaced it; the PowerBook Duo 2300c that came a few years later. Companies were spending vast amount of money on equipment for their staff.

These days you can buy a really decent corporate PC for next to nothing. In fact, if you fancy moving to thin client you can even make it last five years and use open-source software to keep costs down even more.Yet here we are in a world where companies are actively encouraging people to bring their own computers to work and use them for their day jobs.So why is this? And how do you work with them to make sure that both you and your employees get the best from a BYOD (bring your own device) world?You are used to people having various pieces of standard software on their machines: an office suite, email, calendaring, a web browser.Some users have role-specific stuff too – project management software, perhaps, or your particular finance application. If a user moves to BYOD deciding what to install on their device is a no-brainer: nothing that is commercially licensed.Putting licensed corporate software onto users' own machines is a nightmare. The moment one of them leaves (or, even trickier, is fired) you have a problem on your hands because a licensed copy of your software is now floating around in the big wide world.

Yes, you can include clauses in employment contracts insisting that employees who leave must remove any company software and data from their personal devices. But are the clauses really enforceable?Have workers stolen your property? Probably. But what if you catch up with them and they say: “Oh, [insert manager's name here] told me I could keep it if I went quietly”?I have seen it done with expensive laptops, so it is bound to happen with corporate software too. It makes your life difficult when the software vendor counts up the copies of its product that are reporting home to its server with your licence key installed.To give your users access to corporate applications you will need a virtualised infrastructure of some sort – virtual desktops or a Terminal Services-style setup where users log into central servers to run their apps.This isn't a bad thing to do: it means you have excellent control over operating-system and application updates, and if you are sensible about how you build it you can make it look identical to users whether they are in your office or sitting at home.

In return, though, you will want to enforce some kind of standard, primarily to ensure that your users have a web browser that is sufficiently new to work with any apps you have that are (a) browser-based and (b) available without being connected either directly or via VPN to the corporate network.One of the reasons for going for BYOD is to reduce not just your equipment costs but also your support costs. If you own fewer systems you need fewer support staff.It is pretty obvious where you draw the line between what you support and what you don't. For example, if a user can't connect their Mac to the wireless LAN and you can demonstrate that it is working fine (for instance by showing them that their phone is connected OK) then it is their problem.Or is it? The result of people not being able to use their BYOD devices is that they can't do their jobs, which means you as the employer are losing out on productivity.Now, you really don't want to succumb to helping your users out with fixes to their devices. As soon as you have helped one person you will have a queue for the support guys. Then there is the question of liability should someone on your help desk bugger up someone's PC and delete their family photos.

The best approach, then, is to have a handful of thin-client machines in the cupboard which you can give to users whose BYOD machines are out of action, on the strict understanding that there is a limit on how long they can have them for.People's own devices need to be outside the firewall; they access applications via the likes of Terminal Services or a Citrix platform rather than via a VPN (which could be used for malware distribution).You need two-factor authentication to be sure you are sensibly secure. Happily such mechanisms are ten a penny and easy to install these days, so there is no excuse for not doing so.Oh, and remember we mentioned making the experience the same for users at home and in the office? Well, they are outside the firewall in both cases so you can have them accessing precisely the same interface wherever they are.Although you are shying away from buying corporate equipment, consider providing screens or keyboards for the users. They last ages and are cheap to provide. You probably have loads left over, even though you have binned your old, obsolete PCs, and they are a genuine aid to productivity.I am typing this on an ageing MacBook Pro that is fine for just writing stuff, but for my day job as an IT ops manager I crave screen space. I am more productive with project plans, spreadsheets and the like if I don't have to scroll everywhere.

Most of your users' BYOD devices will be laptops, so consider giving them some cheap peripherals.We have already noted that you will be accessing applications remotely, but what about instances when you need to have data on your personal device? The most popular way to work with corporate data on the move is on one's phone.Of particular interest is email, of course, but given that you can natively access many types of document on Android and iOS devices without needing licensed software, people also want to be able to carry data around with them.This throws up an interesting dilemma: if you put corporate data on someone's own device, there is the potential for them to stroll off with it when they leave. Happily, there are plenty of answers to this problem, all of them variations on a theme: the sandbox.The idea is pretty simple. You don't want users to have the data natively on their devices because you have no control over their phones and can't guarantee they will delete it when they leave.When people leave you can simply turn off their access and be happy that they can no longer see the data So you run an application on the device which is registered with a server in your organisation and which “corrals” the data within that application.

The application can be configured to render the data inaccessible unless it can contact the server (or perhaps contact the server within a few hours, otherwise users won't be able to read stuff when they are in 3G deadspots or on the Tube).Hence when people leave you can simply turn off their access and be happy that they can no longer see the data.These products started with email and calendar access with the likes of MobileIron and Good for Enterprise, but nowadays they are far more complex and support more general ranges of applications. They are also much better at addressing the requirement of having a single, personally owned device for both corporate and personal use.So packages like Samsung's Knox and RIM's BlackBerry Balance provide the ability to swap between personal mode and corporate mode on a device, the latter being nailed down by corporate security policies.In some ways it is surprising that it has taken the vendors so long to catch on to this, but we have got there at last. Such packages offer a sensible compromise between controlling corporate data and not allowing the employer to blat personal data when someone leaves the company.

A minute into the meeting, his laptop blinks out. A minute later, everyone is bored shitless and looking at their smartphones again. I am looking up Black Friday.For weeks, I have been receiving press releases, unsolicited marketing email and LinkedIn bollocks – a tautology, I know – telling me how important it is to spend my money in shops on Black Friday, yet not telling me why nor indeed when. My initial wild hunch was that it would take place on a Friday turned out to be correct. But which Friday? And why was it Black?As the whole world apart from me knows only too well, it took place yesterday and the supposed shopping insanity should start putting retailers into the black financially in the frantic run-up to Christmas. It happens, I understand, because it’s the first shopping day of a long holiday weekend that began with Thanksgiving the day before. It’s a bit like the January Sales, I guess, except that I’d never heard of it in my previous 50 years of existence.

Well, hot-dang, hoo-whee and yeefuckinghar, you rootin’ tootin’, shankin’ wankin’ cousins from the Tea Partying land of the free and drive-by shooting. It’s just possible that one or two of us in the primitive, nomadic wilds beyond the borders of civilisation – in my case, south-east London – do not celebrate Thanksgiving. If I did, it would be like this:To give it credit, though, Black Friday 2014 has been a marketing success in the UK in reminding lazy people like me to get buying Christmas presents before December has even begun. In the Dabbsy household, my artificial tree is up, the LEDs twinkling and the decorations already hung. Effectively, Black Friday has turned me into my own Mum. Next thing, I’ll be screaming at my family on Christmas morning not to tear the wrapping paper and will spend Boxing Day ironing it for next year.No doubt The Reg will shortly bring you one of those Best Gadget Stocking Filler type of product roundups. I still hope to read Lucy Orr’s exciting review of the extraordinarily fascinating lightbulb she won in a hi-tech tombola a few weeks ago.

No more misery of having to operate a lamp switch manually for Lucy, oh no: now she can download and install an app, fail to connect to Wi-Fi, restart her router, update her OS, restart her phone, shout “Connect you stupid bugger” and spend half an hour on a call to a Customer Engager in order to turn on the light. Ah, progress.In case you are more of a stop-in than a shopper, Black Friday also featured a TV ad on British commercial channel ITV2 by “intense sensation” specialists Durex just ten minutes after the 9pm watershed. A boring old ad for rubbers? Oh no, young Bucky, nothing of the sort. Instead of watching soft-focused footage of loving heterosexual couples laughing on a sunlight street or clinking wine glasses in a restaurant (as opposed to clips of them grunting and all sweaty while shagging in a damp bedsit to the soundtrack of a fan heater at the foot of the creaking bed), Durex ads have gone all hi-tech.On the dubious premise that British people are reserved and suffer from having an emotional broom handle stuck up their arses, the concept is that they maintain decorum in public while sticking very real broom handles up their arses in private. According to the press release, the British are “tight lipped” about sex and adds, hopefully choosing its words deliberately: “Brits are still maintaining their traditional decorum when it comes to spilling the beans.”

To peek into this secret life of the rampant Brit, you point your smartphone or tablet at the TV ad to trigger a behind-the-scenes view of what they really think.Brilliant. Instead of sitting back to watch a TV ad recommending the barrier method, preferably the ribbed range in fluorescent colours with spermicide lubricant, you can download and install an app, fail to connect to Wi-Fi, restart your router, update your OS, restart your phone, shout “Connect you stupid bugger” and spend half an hour on a call to a Customer Engager.Durex’s press release shone light on the most popular sex toys, so I do hope some of these can be er... slipped into any El Reg gadget roundup. Certainly, I know very little about this field of product engineering. I have worked out that a “clitoral stimulator” stimulates the clitoris but why pet owners would feel compelled to purchase a “rabbit vibrator” to vibrate their rabbits is beyond my comprehension. I shall never be able to look a Duracell bunny in the eye ever again.And on that note, I’ll leave you with the idiomatic slogan that make Durex a best-seller in shit barber shops all over the UK for generations: Something for the Weekend, Sir?

If you're a member of the backroom staff at a big company, you probably spend a lot of time sitting at a desk bashing at a computer. Indeed, in my day job as IT ops manager for a telco I'm delighted to have probably the only truly comfy chair on the premises and my huge desktop screen for the Excel-wrangling that forms part of what I do.For small and medium businesses, however, getting out and doing stuff on the move is the order of the day. Being able to work while out seeing clients, visiting suppliers, wiggling wires in your data centre, or even working at home wiping the noses of sick-note-wielding children is hugely desirable. Even in largish companies the ability to be in touch despite not being on-site brings mutual value: the company benefits from increased productivity through increased availability; on the employee's side the work-life balance is made a little easier by allowing a slightly earlier escape from the office ball and chain each afternoon.Happily we're now at the stage where computing on the move is not just doable, it's positively attractive. Let's look, then, at the ingredients that you need in order to cut the cord without losing touch with the office.

The first thing you'll need to decide is what device(s) you and your users should be using, and this depends entirely on what they'll be used for. So for instance if you don't need to type a great deal or access many apps on the move, a standard iPhone or Android phone may well be sufficient if all you need is email and a bit of internet access. Actually I find something the size of an iPhone 6 Plus about right for this kind of stuff – I recently tested a similarly sized Nokia Lumia 1320 to see if I could live with it as a business device and it was just great.If, on the other hand, you do more “proper” mobile computing with browser- or terminal service-based applications where you use the apps remotely, don't actually store much data on the device itself, and you need a sensible size screen, then you're looking at a ruggedised tablet. Finally, there's no shame in admitting that you need or want a laptop: there are plenty of instances when you do just need to carry an armoury of files around with you and access them without being able to connect back to the office all the time.

Even if you're a laptop jockey you'll still have some requirement for connectivity so you can check email, upload and download files, and so on. And clearly you'll be looking for mobile data on your assorted portable devices.The latter – the phones and the tablets – is an obvious one to deal with: the devices have SIM card slots and you'll need a SIM with a data service if you're to use it for working on the move. There are two things you need to think of in this respect: working in your home country and working elsewhere under “roaming” conditions.Even for small companies I'd suggest arranging a shared data service bundle with your mobile supplier – that is, you have a corporate “bucket” of megabytes/gigabytes and all the handsets eat their data from that bucket. It's usually a whole lot more economical – and is always way easier administratively – than having a data allowance per handset, as some will go over their limit while others will leave much of their allowance unused.For roaming, most suppliers provide “bolt on” data options for users wanting to roam overseas. So for instance my mobile supplier in the Channel Islands has a standard rate of £5.99 per megabyte for data if you're roaming in the EU or USA, but for a five-quid-a-month bolt-on, this comes down to 50p per meg. Others, such as O2 in the UK, allow you to pay by the day (£1.99 per day in Europe, for example) regardless of volume. What about laptops? Well, unless you want to ignore mobile data completely and rely on Starbucks and your hotel WiFi, you have three options here.

Akku LENOVO 57Y4565 www.akkus-laptop.com

Aber selbst wenn Apple den Energieverbrauch reduziert - an die Ausdauer von Highend-Konkurrenten wie das Galaxy Note wird das iPhone 4S auch mit Software-Updates nicht herankommen. Das Samsung-Smartphone erreicht eine typische Ausdauer von 9 Stunden und 31 Minuten, während das iPhone 4S gerade einmal 6 Stunden und 4 Minuten schafft. Hier finden Sie unsere Messergebnisse im Detail: Die Ausdauer-Messungen werden in unserem Testlabor getrennt nach Akkukapazität und Stromverbrauch vorgenommen. Dabei wird der Akku mehrfach ge- und entladen, um sein Speichervermögen im optimalen Zustand festzustellen. Daneben wird der Stromverbrauch des Handys in den verschiedenen Betriebsarten bestimmt, denn die Akkukapazität geteilt durch den Stromverbrauch ergibt die Betriebszeit.Für die Standby- und Funk-Ausdauermessungen dienen geschirmte Spezialkästen, die eine große Messkammer ersetzen. Bei diesen - bis zu belastbaren Daten sehr lang dauernden - Messungen reichen die Boxen völlig aus, solange die Sendeleistung des Handys auf den typischen Mittelwert eingestellt wird.

Auch der Strom bei eingeschaltetem Display wird im Labor ermittelt. Aus den Strömen und der Akkukapazität errechnen wir einen typischen Ausdauerwert. Dieser setzt sich aus einem Mix aus Telefonie, Internet-Nutzung und sonstiger Anwendung zusammen. Er ist ein Maß für die ungefähre Betriebszeit, die ein normaler Nutzer im täglichen Gebrauch erwarten darf. Daneben werden über alle Netze gemittelte Standby-Zeiten ermittelt, die beschreiben, wie schnell sich ein Handy entlädt, wenn es ins Mobilfunknetz eingebucht ist, aber nicht benutzt wird.Totgesagte leben bekanntlich länger - so auch das Smartphone-Betriebssystem Symbian. Galt die teils zähe, aber enorm vielseitige und detaillierte Benutzeroberfläche seit der verkündeten Allianz von Nokia und Microsoft endgültig als Auslaufmodell, pushen die Finnen ihr Baby in letzter Zeit doch enorm. So konnte bereits Symbian Anna mit moderner Optik und spannenden Features auf dem Nokia E6-00 glänzen.Symbian Belle soll nun sogar noch einen Schritt weiter gehen. Zudem steht die aktuellste Softwareversion auch für sieben ältere SmartphonesHier gehts zum Kauf bei Amazon - darunter das E7, N8 und X7 - zum Download bereit.

Das Hauptmenü bietet nur eine Ebene und wirkt bei der großen Anzahl von Einträgen etwas unübersichtlich. Erster Symbian-Belle-Vertreter im connect-Test ist das Nokia 701 für einen empfohlenen Verkaufspreis von 379 Euro. Das Smartphone kommt in einem unauffälligen Gehäuse daher, das in den Farben Schwarz, Silber und Lila lieferbar ist. Verarbeitung sowie Materialauswahl sind jedoch top, der 3,5 Zoll große Touchscreen ist im Alltag dank der Corning-Gorilla-Glass-Abdeckung gegen Kratzer weitgehend immun.Auch die farbstarke Darstellung der Anzeige weiß zu überzeugen. Eine Klasse für sich ist das Display jedoch in puncto Helligkeit: Bei den Messungen erreichte die Anzeige beeindruckende 767 cd/m2 und ist damit auch biergartentauglich - der nächste Sommer kann also kommen.Dazu passt auch die neue Benutzeroberfläche von Symbian Belle, die den Nutzer farbenfroh und detailverliebt, aber dennoch informativ empfängt, etwa beim Uhren- oder Kalender-Widget. Die sechs Ebenen des Startscreens lassen sich nicht nur mit Widgets und Schnellzugriffen, sondern auch jeweils mit unterschiedlichen Hintergründen individualisieren, die beim Wechsel sanft ineinander geblendet werden.

Auch das nach Android-Vorbild gestaltete Pulldown-Menü, das über Verbindungen und Nachrichten informiert, kann überzeugen. Solche netten Spielereien waren früher für Symbian-Smartphones undenkbar.Kritik muss sich das 701 allerdings beim Hauptmenü gefallen lassen, das nun ebenso ungeordnet ist wie bei vielen Android-Modellen. Immerhin kann der Nutzer eingreifen und sich nach eigenem Gusto entsprechende Ordner anlegen, um Übersicht zu schaffen.Was leider nicht zu ändern ist: Der eingeblendeten Schreibmaschinentastatur täten größere Bedienflächen gut.Eine schöne Entwicklung zeigt sich beim Bedientempo. Waren nervige Wartezeiten bei früheren Symbian-Modellen an der Tagesordnung, so drückt das 701 nun aufs Tempo. Wechsel der Startscreen-Ebenen gelingen inklusive schicker Übergänge ebenso flüssig wie das Aufrufen von Programmen. An dieser guten Leistung haben der 1-GHz-Prozessor sowie die üppigen 1 GB RAM ihren Anteil.Apropos Speicher: Hier zeigt sich Nokia großzügig und stellt dem Nutzer über 7 GB zur freien Nutzung bereit. Über den Micro-SD-Slot unter dem Akkudeckel lässt sich der Speicher zudem ganz bequem erweitern.Schwere Geschütze fährt das 701 bei der Ausstattung auf. Der Blick auf die Featureliste offenbart nur wenige Lücken, aber viele Highlights - beispielsweise NFC zum Datentausch im Nahbereich oder einen UKW-Sender, der Musik vom 701 an jedes UKW-Radio funken kann. Hier finden Sie zwei Beispiele für NFC-taugliches Zubehör.

Spendabel zeigt sich Nokia auch bei den vorinstallierten Apps: So hat das 701 nicht nur den Sports Tracker, die kostenlose hauseigene Navigation, ein Wörterbuch samt Übersetzung sowie diverse Spiele mit NFC-Funktion an Bord, sondern auch reichlich Businessfunktionen. Nachschub bietet der Ovi Store.Das hohe Niveau von Handhabung und Ausstattung konnte das 701 bei den Messungen im Labor nicht halten. Zwar bietet das Nokia gute Leistungen beim Empfang und ordentliche bei der Ausdauer. Die Ergebnisse für die Sprechzeit und die typische Ausdauer liegen aber nur im Mittelfeld. Alles in allem kann das 701 aber überzeugen. Der akkubetriebene Speaker soll für Rundum-Sound sorgen. Die Box für 170 Euro kommt im Alugehäuse und wird von einem Akku mit Energie versorgt. Als besonderer Clou lassen sich zwei Exemplare als Stereospeaker konfigurieren. Der Sound gelangt per Kabel oder Bluetooth zur Box, die Kopplung erfolgt per NFC.

Das praktisches In-Ear-Bügelheadset bietet viele Funktionen. Das BH-505 ist in drei Farben zu je 60 Euro lieferbar. Der Ton gelangt per Bluetooth vom Telefon zum Lauscher, die Kopplung erfolgt per NFC. Titelsprung, Lautstärke und auch die Rufannahme lassen sich direkt am HeadsetDas Nokia Lumia 800 ist eines der ersten Nokia-Smartphones mit Windows Phone 7.5 Mango und ab 15. November in Deutschland erhältlich. connect hat das neue Nokia-Handy ausgepackt.Ein echter Hingucker ist es auf jeden Fall, besonders die Versionen in den Farben Cyan und Magenta stehen eindeutig für das Nokia Lumia 800. Einige Marktbeobachter hatten bei einem so eminent wichtigen Produkt wie dem ersten Windows Phone von Nokia eine Metallschale erwartet, am besten aus dem High-Tech-Werkstoff Titan. Nokia-Chef Elop aber will wohl lieber technisch überzeugen als durch vermeintlich teure Materialien zu blenden.Neben der guten Haptik und der sehr guten Verarbeitung des Lumia 800 fallen beim ersten Ausprobieren auch einige ungewöhnliche Dinge auf. So finden sich an der Oberseite des Smartphones zwei längliche Abdeckungen. Unter denen treten die normalerweise unten angebrachten Micro-USB-Buchse und der SIM-Karten-Slot zu Tage. Letzterer steckt bei den meisten Smartphones im Akkufach. Doch den hat das Nokia Lumia 800 nicht; um einen großen Akku mit einem sehr stabilen Gehäuse zu kombinieren, hat Nokia auf die Möglichkeit zum Akkuwechsel verzichtet.

Nokia hat das Microsoft-Betriebssystem Windows Phone 7.5 Mango um zwei weitere, sehr hilfreiche Features erweitert. Das eine ist die Turn-by-turn-Navigation mit Sprachansage Nokia Drive; das andere ist Nokia Music, ein Angebot für Music-Streams, in Deutschland vorerst aber nicht verfügbar.Von 15 Stunden ununterbrochener Betriebslaufzeit abseits der Steckdose war in der Pressemitteilung des MSI Wind U160 zu lesen. Das wäre sogar für ein Netbook eine rekordverdächtige Leistung, obwohl Mobilrechner mit extremem Stehvermögen in dieser Kategorie keineswegs selten sind. Da das U160 in der von uns getesteten preiswertesten Ausführung zudem gerade mal 349 Euro kostet, bot es sich an, dem Wunder nachzuspüren.Der Akku ist mit rund 65 Wattstunden sehr üppig ausgefallen; bisher gab es ein Netbook von Asus und eins von HP in der gleichen Liga. Knapp unter 60 Watt liegen alle von uns getesteten Acer-Netbooks und zwei Modelle von Samsung. Hier besitzt das MSI also eine gute Grundlage.
