My Windows 7 computer no longer turns off properly. If I shut the screen, it no longer sleeps or hibernates, it just freezes. If I go through the start menu to hibernate, it will do so, but the computer is still on -- the power and the wifi lights stay on, it's still running and using battery. This also happens if I go through the start menu to turn off the computer. If I hold on the power key, it will then turn off and restart or resume from hibernation normally when I turn it back on.

I am tired of this damn computer and its numerous problems. Before this, I've had to replace newly bought RAM and a new HDD, a motherboard and oh so much more. Anyway, moving on. After a power outage I had while running my computer, it has never been the same. [more inside]

Hello IT, have you tried turning off and on again? I'm in need of a short extension cord, with a separate, big button toggle switch. Extra difficulty: It needs a short time delay before it powers back on. Any ideas? [specifics inside] [more inside]
My laptop power cord's ground prong (the third prong) broke off, and it stopped working in most wall plugs. I ordered a new one and when it came, it didn't have a third prong, but it works fine. Why is that? And more importantly, is there some future situation where I'm going to regret not replacing the old one with a new, three-prong plug? [more inside]
After a move, our computer (an older aOpen desktop) can't sleep through the night. It's fine if we leave it powered on, but if we put it to sleep, it seems to lose power sometime in the night and does not wake up properly in the morning. Will a cheap UPS (this one
, for example) solve the problem? Any other ideas?

There's a sick computer I'm trying to diagnose & I have no idea why it's doing what it's doing. It's a custom Intel-based desktop from maybe 3-5 years ago, can't easily read the mobo maker but if it's needed I can probably get it. When I hit the soft power switch it turns on briefly, the front power light comes on & the fan spins up then it all shuts down inside of half a second. Any ideas?
My sister and brother-in-law have a large (12) and growing number of desktop boxes at home. They're rightly concerned that they're putting a strain on the electrical circuits they're using. What should they be asking an electrician to do to set them up correctly? [more inside]
Moving a desktop computer internationally - we're moving from Korea (220 V) to Canada (110V). Is it as simple as removing the power "section" of the desktop and replacing it with 110 V at a computer repair place in Canada? Are internal components individually responsive to a particular voltage?
Just returned from fabulous 2 week holiday in New York. I Brought back Epson Artisan 800 All-in-One Printer from Staples costing $230. Unfortunately, I cannot use it in U.K., unless I plug voltage converter/transformer products. Has anyone else bought this set over there with more success?
Any advice \ information appreciated.
Please specify me What exact voltage converter product to buy & where to buy it from USA online store. Thanks. [more inside]

[DirtyPowerFilter] My CRT monitor has developed a nasty shake/vibration at certain refresh settings, since I moved to a new apartment. I think the problem stems from the old electrical system.

How do you secure a plug so that even if someone yanks on the chord, it doesn't come out of an outlet? It does need to be POSSIBLE to get the plug out sometimes, and it won't work to glue/staple the chord to the wall, because sometimes equipment needs to be moved to another room. [more inside]

The power connector to my G4 Powerbook is almost dead. It only charges in one very specific position, and I have to twist it around for a few seconds to find the sweetspot (rotating it in situ). Nothing is loose and nothing is visibly wrong. I tried squeezing the metal sleeve slightly to make it more elliptical in the hope this would create a tighter connection, but it made no difference.

I am in the process of building an AMD Sempron 2400+ based file storage machine. I am seeking recommendation for how big a power supply I need.
I am planning on 4 to 5 (may be 6 in future) 250GB Seagates, 2x320GB WD Sata drives, 1 DVD writer, Geforce FX 5500 video card.
The $50 case has a stock 480W PSU. I am wondering if I need more juice and possibly something by a well known brand ?
I recently built an Athlon box with Seasonic 430 PSU. Seems pretty quiet. Not sure if I should get another of those.
I opened up my computer and tried to install RAM. After I installed the RAM, my computer would not come back on. I pressed the power button multiple times, and nothing. A friend checked to see if the power button was faulty and it wasn't. It's a Compaq Presario HP and when we plug the power cord in, the power supply just does this clicking. We're not sure what the problem is. I tried a new power cord and still no luck! Any ideas?
It keeps shutting down at random. [more inside]
Hey, is it better to keep an external hard drive plugged into and constantly running, or is it safer (for archiving and the health of the drive, avoiding power failures that might otherwise zap an entire machine, etc) to only turn it on and connect it when you use it? Thanks as always for your thoughts.
