comment Why are my games slower on battery power, even with the power plan set to High Performance?
@misha256 You get 2 or 3 of the following: 1) the cheap battery pack that's partially fully of air. 2) The normal battery pack that fills the standard size enclosure. 3) The oversize battery pack that extends outside the normal limits by either bulging out below or behind the main body of the laptop.

comment What is a PCI-Express Lane?
Single port gigabit networking cards don't need multiple lanes. Even a PCIe 1.0 lane offers 250MBps = 2000Gbps of bandwidth; which is enough to allow for 50% overhead losses while still being able to keep a gigabit port saturated. Multiport gigabit cards can need more than one lane; but if that's what you were referring to you should be more specific since they're generally not something seen outside of a server room.

comment What are the three buttons above touchpad in the Dell Latitude E6520 laptop?
@Kos you need to buy your next Dell from the Small Business section of the website. The pointy sticks are limited to (some) Latitude and Precision models. Alternately, some Thinkpads offer them; and at one point so did some HP business class models (not sure if they still do or not).

comment How can I tell which version of Windows was installed before update?
The error reporting log appears to get truncated as well. My oldest event there is from about 10 months ago, on an install that's several years old.

comment Why are Ethernet/MAC addresses needed?
@user2449761 All packets only go to all computers if you're using ancient networking hardware that has hubs instead of switches. Hubs were originally an option for cost reasons; but now that switches are cheap nobody uses them anymore.

comment Can a 7 days full 100% CPU load “burn-in” / “stress test” damage a modern notebook?
As a counter example, I ran a cheap 15" Acer laptop at near 100% load from 2006-2013 (distributed computing); and aside from a fan replacement at the ~5 year mark it was still working well when I gave it to a family member who needed an emergency replacement computer. AFAIK it's still running well today.

comment Can I add another stick of 2 GB to a 32 bit Windows Starter system?
It's not quite useless. While the OS is limiting you to 2gb of usable ram; going from single to dual channel mode will double ram bandwidth and should give a modest improvement in real world speed when doing anything computationally intensive.

comment What is the relationship between Unix, Linux, Ubuntu and Debian?
At the same time, any non-trivial distro these days is going to include lots of stuff that is neither part of GNU nor the Linux kernel itself. Does anyone really want to chain all of those into a name less practical than the full titles of reigning monarchs?

comment What is the relationship between Unix, Linux, Ubuntu and Debian?
Outside of the FSF, most people just roll their eyes whenever Stallman insists on the use of GNU/Linux and continue to only use the latter. In some ways that's not really fair; but such is the real world.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
I suspect page file in a ramdrive started out as a cargo cult "workaround" for the fact that some software will refuse to start if it detects there isn't a page file. (I've been told Adobe's graphics/video tools do this.)

comment What is the name of the cable inside PC cases?
The reason they have 2 ground wires is that it allows using the same gauge of wire for all the connections; with only a single ground wire a thicker wire would be needed to avoid overload when both the +5 and +12v lines were fully loaded.

comment Can I repair a physically broken USB drive?
IF you don't have a computer with a sacrificial port; you can get a cheap USB hub for <$10 and to plug into that instead.

comment Excel VBA program only running at 25% speed
If you're concerned about run time, porting your computational logic into another platform would be a very good idea. I achieved an ~1000x speedup porting some very computationally intensive code from (Excel 03) VBA to C#: ~4 hours vs ~15 seconds. Same algorithm in both cases; and the VBA had already gotten a 5-10x speedup over the naive implementation by caching values to variables instead of reading the cell every time and disabling refreshing of the spreadsheet on screen every time a cell was changed during the computation.

comment Can I add RAM sticks from an old PC to improve the performance of the new one?
@AwalGarg there've been a lot more than 3 ram standards. Going backwards you've got DDR1, Rambus, SDR, EDO, FPM... and that's just the last 20 years and ignores ram used for uses other than PC main memory.

comment Swap partition size on a 64 GB RAM computer for memory-intensive work
+1 for the last paragraph. The 2x recommendation dates back to when most computers didn't have enough ram to avoid swapping in normal use. Subjectively, from using computers then, the 2x limit appears to've been selected as a number big enough that the computer will become unusably slow before running out of swap.
