Modern Standby Sleep in Windows 10. Overview, tests, problems.

Tags: , , ,


The always-on feature called Connected Standby in Windows 8 has been updated for Windows 10. Modern Standby, as it is now known, has support for HDD-based PCs and allows you to disable WiFi during Sleep which will help preserve battery life. Windows 10 also includes easier controls for preventing applications to run in the background and for controlling notifications which also extend to a new Battery Saver mode. I’ve tested the features on a couple of Windows 10 devices (upgrades) and the results have been extremely varied. This Windows 10 feature needs more work but it’s a huge potential advantage to mobile battery life when compared to Windows 8.

ASUS T100HA 14-hour battery life claim looks suspicious.

Tags: , ,


“14 hours battery life when Web browsing” is the claim made by Asus for the new Atom X5-based Transformer T100HA.  Given the size and weight of this tablet (the keyboard doesn’t have an extra battery,) that’s huge. So huge that I don’t believe it. I’d like to believe it but my history of testing PCs based on Intel Atom processing platforms tells me to question it. I’ve done that below.

Ainol Mini PC has everything + battery for $129

Tags: , , , , , ,


I use my Intel NUC with Atom N2820 processor daily. It’s quiet, neat and runs Openelec like a dream. It was cheap too but now I’m wondering if I should have waited. The Ainol Mini PC comes with RAM, storage, a Windows OS and a 26 Wh battery for just $129. It’s silent too!

It doesn’t have a Gigabit Ethernet port but it does have USB3.0 so adding an adaptor is no problem. Retro-fitting an infra-red reciever might be a problem though and of course this Baytrail-T ‘tablet without screen’ is not going to allow for any expansion. The storage won’t be as fast as what’s possible with the SATA interface on an Intel NUC. The biggest problem I see though is that you might have problems installing your favorite Linux distro on this due to the 32-bit UEFI bug.  Some tablets come with a 64-bit Windows not but you can clearly see that this 64-bit CPU is running a 32-bit Windows version on the Geekbuying sales page.

Along with the Baytrail-T-based dongles these are interesting IoT-style products (and with a 3G dongle could be the perfect malicious hotspot) but until they allow you to boot your chosen 64-bit OS they’re not flexible enough. If anyone finds a similar one with 64-bit UEFI bootloader, let us know.

Acer Aspire Switch 10 Keyboard Battery Coming?

Tags: , , ,


I’m testing the Acer Aspire Switch 10 for Notebookcheck.net right now and it’s going well. I prefer it to the ASUS Transformer Book T100 because of the better keyboard, mouse and screen but there’s one little issue – battery life. The Switch 10 has a 24Wh battery inside which is much less than the 34Wh battery of the ASUS T100 and less than half of what you got on the previous W510. Looking at the keyboard reveals that it’s quite light and has 8 exposed screws so naturally I took a look inside. What I saw was encouraging because there’s space, screw holes and an unused PCB header space.

Dell Venue 11 Pro (Baytrail) Tablet and Tablet Keyboard Review

Tags: , , , , , ,


Dell Venue 11 Pro (1)

In our last review we looked at an 8-inch tablet running on the Atom Z3740 costing under $300. In this review we have the Dell Venue 11 Pro 10.8 inch tablet running the current high-end Z3770 CPU and costing $499. The powered keyboard is an additional accessory at $159. The two units are extremely well built but are they worth it? We take a look in our detailed Dell Venue 11 Pro  review.

Samsung Series 5 Ultrabook Battery Replacement

Take a look at the back of most Ultrabooks and you’ll find nothing. By having sealed-in batteries the OEMS save money, weight and space. The owner, however, is left with the big unknown of battery lifetime and if you’ve ever owned a laptop you’ll know how totally useless they are when you have to drag the mains cable around with you everywhere. I recently had to order a new internal battery for a Samsung Series 5 NP530 that is under two years old and has zero battery capacity. On the other hand I’m typing this on a two-year old Ultrabook that still has 85% battery capacity. So how long will the average battery last?

I’ve been using the Mobile Reporting Kit V12 over the last 5 days and it’s been working well. The challenge was to work through a day without any cables. No charging! The Harris Beach Ultrabook, Nokia Lumia 925 plus a  backup phone (Nokia 808) and a camera (Lumix FZ150) worked together to give me my best mobile media studio yet.

As I wrote about driver update V2.04 for the Acer W510 I noticed a few user reports of poor connected standby battery life. The following day I heard about V2.08. I updated again but I was seeing some serious Connected Standby issues. Battery life was way below what it should have been.

Here’s some information about how you can access a very cool battery life report on Windows 8, check your CS figures and potentially fix your problem. I hope you take the time to contribute your report or thoughts in the comments below too.

USB Power Delivery Is Ready to Charge Your Next Ultrabook

Tags: , , , ,


The adoption of Micro-USB as a charging port standard on smartphones was a breakthrough for the consumer but we’re still left with the same problem on our other portable electronics. Example: I just spent 10 minutes searching for a power adaptor for a Tablet here in the office. What if we could do the same for portable electronics as we did for smartphones? Power over USB (or USB Power Delivery as it’s officially known) looks like it could be the answer. POUSB Read the full story

Why I’m not a Fan of Wireless Charging

Tags: , ,


I’m not a fan of wireless charging. I love the idea of cable-less operation but the inefficiencies far outweigh the advantages for me. Maybe I’m just too focused on mobile operation though because I agree, there’s a case for desk-top charging while working. Even though, wouldn’t it be easier to just have a separate charging mat?

How to Get the Most Battery Life out of Your Ultrabook

Tags: , , , , , , , , ,


Intel’s Core processors dynamically adjust the speed of your Ultrabook’s CPU to give you power when you need it and battery savings when you don’t. The battery savings come when your Core processor intelligently clocks itself down to the minimum level during tasks that don’t require much power. For instance, as I write this and listen to a song in the background my processor is in ‘Energy Saver’ mode where unneeded cores are disabled to save power and active cores are clocked down. Ensuring that your Ultrabook is correctly downclocking and entering Energy Saver mode is vital to achieving maximum battery life. Inefficient programs or processes running in the background of your Ultrabook could be preventing you from getting the most from your battery; this guide will show you how to get rid of them.
