Sometimes after restarting the level of brightness is much higher than before the restart. Can't pin down reproducible sequence of actions, it seems to occur intermittently without any discernible pattern. I think you may be right that this "brilliant" effect happens on battery, but I couldn't...

You could try running powercfg /energy which also generates a report to examine: <some directory>\energy-report.html. There's a section in the report (about halfway through) describing the battery capacity. On my SP2 the figures in the energy-report were somewhat different than the...

Hyper-V has been enabled on my SP2 since a few days after acquiring it (~2 wks ago). It has the (apparent) effect of "locking" the CPU speed to 2.49 GHz, and according to Task Manager it never varies. The Hyper-V service runs quietly in the background, and by itself doesn't noticeably reduce...

Ran the sfc /scannow utility and it did take quite a while to complete the system scan, 10 minutes almost exactly. While running CPU load was ~25%, and core temp rose to ~65/C. Other than things getting a little warm, all was good. The program found no "integrity violations", more than can be...

The SP2 behavior has been inconsistent and puzzling. Hibernation seems to work on my SP2, at least when I leave it sleeping at night, in the morning it's in hibernation. Since it's been plugged in, I don't know about battery drain overnight, but that does give me an idea of the experiment to...

From evberything I've read, setting up dual-boot with two Windows installations, the preferred method is to install the 2nd version into a VHD(X), and then using the VHD as a partition to boot into. There are tons of articles on the web describing how to do this, and various free tools make it...

AFAICT with just a few exceptions among forum posters, the Jan 2014 FW update has not been troublesome to owners of SP2's unaffected by the Dec10FW problems, and may have corrected a few issues for machines damaged by the Dec10FW. That is, the predominant opinion seems to be the updates you...

My experience with Windows 8/8.1 is limited to the SP2, so I couldn't generalize to other systems. However the issue with abnormally high CPU utilization occurs under specific conditions: (cold boot OR wake from hibernation) AND (an mSD card in the slot AND the Realtek sound driver enabled)...

FWIW I've been noticing similar fluctuating values in full charge capacity, which are hard to understand, how it's calculated isn't really clear. It's also confusing how "cycles" are determined. The battery in my SP2 has been drained almost to zero (down to ~10%) well more than 4 times...

I'll have to get back to your post later--only have a second right now. But 'xVHD' was a slip of the typing fingers. Should be VHDX, the extended VHD format, VHD with enhanced capabilities. More later...

Good timing, I've been contemplating related questions lately. First of all, when you say "two separate" environments it's not clear what you mean. Mainly, are the two "environments" intended to share information or are they really separate, that is, running one at a time, not both at the same...

Good idea, though I'd guess kind of a long shot whether the author (or anyone) has success booting a non-Windows OS installed in a VHD. In principle I imagine it would work, but what are the odds some devilish details will get in the way... :)

AFAIK some current Linux distributions, and FreeBSD 10.0, now come with Hyper-V drivers "built-in" so that these OS will run in a Hyper-V VM and have access to host services such as networking and storage (disks, etc.). And I know this works quite well with FBSD, as well as CentOS, and Suse...

Just to make the waters slightly muddier, after testing it several times, waking from hibernation gives the same CPU utilization effect as cold booting. That is, the CPU load will stabilize at 33% or so, until the SP2 enters sleep and awakens. Then the CPU load drops to the normal 0-2%...

I'd have to agree with idea expressed by olimjj above. I've come to regard "update" or "upgrade" as the most fearsome terms in computing. My policy with all OS is installing updates only after there's ample evidence that the upgrade is "safe". So I'd recommend disabling automatic updates. I...

Still have to find out more, but it seems like an alternative to Hyper-V since it would be booting into the OS installed in the VHD. As it could be a wide variety of OS, including older versions of Windows, I wonder if there are issues with Secure Boot, etc., or if the method bypasses such...

Of course, mileage does vary. I started out with an SP2 with the 4200u, but replaced with a 4300u because the first unit was creamed by the Dec10FW event. With both machines, the CPU speed has varied quite a bit, depending on conditions, per report of Task Mgr. The 4300u has clocked in at...

Probably not. Part of the (vertical) stand stability problem may be the angle it emerges from the body (when the stand extended of course). At the maximum angle it still isn't perpendicular. My issue with the kick stand is a little different but may coincide with yours. I think it does not...

I've been using Hyper-V since getting the SP2, in fact, it's one of the reasons I bought the SP2. The idea is running an OS like FreeBSD in Hyper-V, allowing remote development/maintenance of programs which run on unix platforms. At this point most of the kinks are worked out. Connecting to a...

No special magic at work, just a cautious approach to reduce power usage. The usual things apply: minimizing the number of processes running, turning off most GUI effects, use power saving options and as much as possible, when on battery power avoid running graphic-intensive programs. In...
