Acer Aspire 7750z Battery

Still, at least you’ll be getting a laptop that you can safely let the kids loose on from time to time and even pass it on to them when the time comes. Let’s get one thing out of the way. The T300 is not a budget buy. At a penny less than £800 it’s competing against some quality kit like Microsoft’s 12-inch Surface Pro 3, the 13.3-inch Lenovo Yoga 3 Pro and Apple’s 11-inch MacBook Air. Just as well then that, spec-for-spec and as a package, it stands up well against all three.To start with you get a 12.5-inch 2,560 x 1,440, 245ppi IPS display. And it’s quite a display. Bright, colourful and with viewing angles so robust you could look at it while standing in a parallel dimension. However, it is very reflective which can be a pain in the backside outdoors. While there have been reports that some T300s suffer from backlight bleed, this wasn’t a problem with mine.The tablet part of the T300 weighs 720g which is impressive for something measuring 12.5-inches corner to corner and it is only 7.6mm thick. That means you can actually use the thing as a tablet for gaming or reading and not end up with chronic arm ache.

With the keyboard attached, those figures jump to 1.43kg (a MacBook weighs 1.08kg for comparison) and 16mm (MacBook Air: 17mm). The hinge mechanism is a masterclass in making something thinner than it has any business being, and yet still feels robust and durable.Thanks to both tablet and dock being made from aluminium, they are as solid as a rock. The tablet component has absolutely no flex to it. You could happily engage in combat with the thing and not do it lasting harm. It’s a handsome beast, too, thanks to a dark blue anodised finish.If you reckon Chrome is eating up your laptop's battery, you're not alone. Google is concerned, too, but it says it's not all its fault – Adobe's to blame.Specifically, the culprit is the Adobe Flash plugin that comes built into Chrome and which automatically displays any Flash content it finds on web pages, according to Google software engineer Tommy Li.

"Adobe Flash allows web pages to display rich content – but sometimes that can put a squeeze on your laptop's battery," Li said in a blog post on Thursday.To address this, Google has come up with a new fix for its browser – working with Adobe, naturally – that helps curb Chrome's juice jones by running Flash content selectively, rather than letting every item of Flash on a given page run all at once."When you're on a webpage that runs Flash, we'll intelligently pause content (like Flash animations) that aren't central to the webpage, while keeping central content (like a video) playing without interruption," Li said. "If we accidentally pause something you were interested in, you can just click it to resume playback."Li didn't post any before-and-after benchmarks to illustrate what impact this change has on battery life, saying only that it "significantly reduces power consumption."The interesting part is that Chrome can already do what Li describes. In the Chrome desktop browser's Content Settings, under the Privacy heading, there is a setting called Plugins. By default it's set to "Run all plugin content (recommended)," but another option is "Detect and run important plugin content." That's the fix Li is talking about.

Beginning with the latest Chrome Beta version, which was released on Thursday, "Detect and run important plugin content" will be the default setting. The same change will roll out to Stable versions of desktop Chrome in the near future.The parenthetical "recommended" will also be removed from the "Run all plugin content" option.Naturally, when your Chrome is next updated, you'll still be able to switch back to the setting's original default, if that's what you prefer. Or, if you think it's high time someone did something about all the Flash content on the web and the corresponding drain on your battery, by all means, go ahead and enable the setting now.Li said Google plans to roll out other updates that will reduce Chrome's power consumption even further in the coming months. Comment It’s only taken thirty years, but we’ll soon have one plug that, on paper, does it all: power, video and all kinds of peripherals. Cue headlines about “one cable to rule them all”. And it’s reversible!

However, “soon” isn’t “now”. It’s going to be a confusing and expensive journey before the promises are fulfilled.The last piece in the jigsaw fell into place yesterday at Computex, and cemented the USB-C socket as the winner. Intel announced that the third generation of Thunderbolt will support USB-C plugs.So only one kind of plug is needed to support power, video and audio, and high-throughput data peripherals such as disk drives.But that doesn’t mean one cable will support everything: there will be several different kinds of USB-C supporting different capabilities, ensuring confusion continues for some time to come.The reason is obvious to the tech-savvy, but less so for the typical user who has wandered into PC World on a Saturday morning. The plugs may be the same, but the capabilities are defined by the gadgets at each end of it.Since the expense is defined by the capabilities of the host controller, it all depends on how much the market-conscious manufacturer wanted to spend.Most people who’ll see a USB-C socket won’t be getting Thunderbolt 3 performance, as the Thunderbolt hardware is a luxury-priced item that will continue to be in high-performance hardware, rather than the value mass-market.

So the industry is moving to “one plug”, but retains lots of different standards. At least in the bad old days, you knew you couldn’t plug your projector monitor into the modem port and expect it to work. It wouldn’t fit.Right now we have two flavours of USB-C using the USB 3.x protocol: Gen 1 (5Gbps) and Gen 2 (10Gbps). Some companies throw the old USB 2 protocol through the physical USB-C connector, but we'll ignore those and focus on USB 3.x.The USB-C spec provides a few performance tweaks: asynchronous traffic flow, smarter power management, and more throughput for power and data. At its most basic, USB-C Gen 1 is USB 3.0 renamed: it's USB 3.0 with support for the new physical plug.Nokia’s N1 tablet conforms to this minimum: you’re getting one plug to charge the device with that also being a data port. But not much else. The host controller has a USB 3.0 feature set.Gen 2 is where the action is, but here, capabilities are moving along parallel (no pun intended) development tracks, moving at different (no analogy intended) speeds.

USB ‘Alternate Mode’ is what gives Type-C ports the ability to support other protocols, such as DisplayPort (or Thunderbolt). This requires the co-operation of the non-USB peripheral working groups, and it’s still very early days. (Type-C itself was only announced in December).The power capabilities of Type-C have their own working group and spec: USB Power Delivery. And there’s USB-over-radio, being pursued by two groups, the old UWB-inspired Wireless USB group, and this one. You can’t have too many computer standards, as the old joke goes. Just call them all USB.So clear consumer labelling is going to be needed, but the personal computer industry hasn’t done a fantastic job on this in the past, even on simple transitions. USB 2.0 was High Speed, 3.0 SuperSpeed. Now the consumer in PC World will see one plug, but won’t be sure whether it will support, or not support, that particular monitor (“4K or not?”), or that particular drive or array, or be sure whether it provides enough power to charge that laptop and a phone at the same time.

Perhaps it would have been clearer to call USB Type-C “NooSB” or “Newport” (the council would be glad of the publicity) with something to label the feature set.Even for a tech savvy user – as most of you are – it needs a bit of homework. And since many of us act as tech support for less tech savvy friends and relatives, we're going to be kept pretty busy. All hail USB. Many companies put staff engagement high on the agenda: they reason that if you keep staff happy they are likely to be productive and stick with you through difficult times as well as when it is all going swimmingly.It is a perfectly sensible thing to do – so long as you involve the IT department in the process.My first IT support role was in 1989 and in those 25-plus years I have witnessed my fair share of horror stories that were caused entirely by the company's desire to keep its users happy.This has sometimes taken the form of an approved company policy created for staff engagement purposes. But it is equally sometimes the case that a well-meaning individual has done something a bit daft – though generally not with malice aforethought.
