Power Cord On Desktop Keeps Melting
Nov 11, 2012
I have a Phillips desktop machine which up to a few weeks ago was running fine. 4 weeks back I was running a virus scan and left the machine alone only to return an hour later and find the machine off and the power cord at the back completely melted at the connector.After an initial panick I replaced the cord and the machine booted up again and ran absolutely fine.4 weeks have passed now and today I noticed a burning smell whilst the computer was on and I noticed the power cord was starting to seriously melt again.

I am traveling to Hong Kong in a couple of months. My HP laptop is from the US. It has an external power brick that takes 100-240V.My question is about the cord that goes from the power brick to the wall outlet. The cord has a US plug. Does the cord also take 100-240V and I just need to buy a plug adapter, or does the cord only take US voltage and I need to buy a new cord?

I have had this issue for a while with my Dell Studio XPS 1645 laptop. It is a guess, but i'd say 5/10 times the power cord comes out of the laptop (for whatever reason - moving it etc) then the laptop will simply black screen and instantly restart and boot up again without an error message or any information as to why. This doesn't make any sense to me because every time I do have the battery pack inserted into the laptop and over 30% battery life (this is when ill plug the charger in).

I have a laptop with Win 7 HP 32bit SP1, which doesnt boot at all, if the power cord (AC Adapter/Battery charger) is plugged in. Further if power cord is plugged in after booting, the system hangs / shuts down. It runs fine on safe mode. I believe it is a driver updation problem but not sure. I have updated all drivers given in Toshiba download site.

When I remove the power cord of a cpu while working, it often makes windows 7 crashes hard. When that happens, Windows 7 by default makes a system restore. Since we don't want that, we removed this option. Since the system restore has been desactivated, Windows 7 reboot over and over again. I have to reinstall. Sometimes, even the safe mode is not working. This scenario does not happen every time because sometimes Windows 7 succeeds in "getting back" online.

I have an HP Laptop model 6735b with an AMD Turion DualCore ZM-84 Mobile processor and 2GB of RAM. I purchased it in January 2009 and installed windows XP on it, which I had no problems with. I recently installed Windows 7 on it, and it will not power down or go into hibernate mode without being on external power. When I tell it to hibernate or shut down it will power the screen down, but thats as far as it will go without being plugged in. All of the lights stay on (volume control buttons, wifi indicator, etc.), the hard drive continues to run, and it will stay like this until I plug it in, at which point it will finish its power-down or hibernation.

I am currently building a custom desktop (Specifications in My System Specs) and I've run into a few problems along the way:
- When I first put it all together and powered it up, the edge of the motherboard literally caught on fire for a second and I immeadiately turned the power off.
- I returned the motherboard and the psu and got both brand new again.
- I just tried to reinstall the motherboard and psu and now I get no power at all to the pc.
- I checked all connectors to make sure they were plugged in tightly and correctly. Everything looked fine. The 12V atx power connector and 24-pin connector were both plugged in correctly.
- I checked the psu with a paper clip and checked the voltage of each pin that should have been outputting voltage. Everything was fine there. And the psu powered up and the fans turned as soon as I pressed the switch.
- Checked for bad heads on the motherboard. None.
- I also went through all of these steps already: PERFORM THESE STEPS before posting about POST/boot/no video problems! - New-System-Build - Homebuilt-Systems

Obviously there a many, many different home desktop configurations out there. From a top of the line latest desktop setup to one that's 6 or 7 years old but is there an accepted "average" electrical power usage for the "common' home desktop PC? How would one estimate/check an individual desktop PC's energy use (ie. cost per hour or day if left on 24hrs) without having to purchase any expensive watt-o-meter type unit ?

Is there a way to show the Power notification icon in the system tray on a desktop?
In "Turn system icons on or off", the drop-down menu beside Power is grayed out and set to off. After a google search, I found a registry tweak wherein I'm supposed to delete some registry keys that hide notification icons, but these registry keys don't exist.
Keep in mind that I'm on a desktop, which might be why it is disabled. I don't have a UPS so there is no battery to monitor, but I'd like to be able to switch power plans quickly. I might just have to stick with a desktop shortcut.

Desktop does not respond to mouse actions as previously nor the front panel power switch.I have to disconnect the power cord, reconnect, and press the front panel power button. Then the unit starts up and returns to window without the login window as if it was sleeping.The problem started after my attempts to install a defective external drive enclosure connected with an esata cable. I have since obtained a working external enclosure connected with an esata cable. The present Sleep wakeup malfunction is now present with or without a working external drive.

I've done a lot of searches using variations of the above title and came up empty or just plain missed the answer.I'd like to know, if it is not asking too much, the following points:
1. What exactly is the function of Link State Power Management in the Power Options Advanced Settings, PCI Express?
2. What are the implications of using the options available:
a) Off.
b) Maximum power savings.
c) Moderate power savings.
d) Which option is the best selection for my Dell laptop.

I use my PC for audio production and I have a few external controller devices that are USB powered, for example a midi keyboard. I recently had to build PC due to a theft....long story short after building the new PC I've noticed that my USB buses have continual power to these external devices after I've powered down the PC. My old windows 7 PC did not do this. Is there a setting I can change to shut off power to the USB buses when I power off the PC? Or is this a hardware issue?

Over the past 2 years my PC has been afflicted with random power off/power on/reboot events.It will go for months without these and then have multiples of the events in a day. (I had 8 of them 3 days ago.)I assume I have a hardware problem, but nothing has been found and I'm grasping at straws.The time between power off and power on is several seconds.I had assumed this rules out a software cause, but maybe I'm wrong. I know Windows can schedule a power off, but can it tell BIOS (or something) to power back on in a few seconds?I know blaming the power supply is a much more simple explanation, but then I'm left with explaining the intermittent nature of the failure.

My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.

When I save files from programs (aka Word, Photoshop, anything)onto my Desktop, I cannot see them directly from the actual desktop. I can only see them when I open up Explorer, and click on the Desktop tab. Then all my files are visible. I thought they were hidden...but they apparently aren't.It possibly seems like a refresh error.I did find a way around this..I go to Control Panel >> Appearance and Personalization >> Under Folder Options >> Show Hidden Files and Folders. I click on Reset folders, Apply, and then OK, and my missing files pop up on my actual desktop.But from then on, any new files I save are only visible in Explorer again. I don't want to go to Control Panel everytime I have to save something to the desktop? I've run Norton and Microsoft Essentials and I have no viruses. What can I do?I just found out I can also see my files after pressing f5 (refresh)so I guess the problem is HOW do I get my computer to refresh the desktop automatically?

I've been looking around for something that can hide my desktop icons (or basically anything except my background & bottom navigation bar) if I'm not viewing the desktop.In other words, when I have a (not full screen) window open, I want to be able to see my desktop background but not the icons on it. When I "view" the desktop, or don't have anything on top of it, I want the icons back.

I have a really annoying problem with desktop icons.I use 2 monitors. 1920x1200 is the main dislay and 1600x1200 is another one for extended desktop. The thing is that I don't need it all the time so I'd like to switch the extended desktop on and off when I need it. Problem is that entering the ex. desktop just somehow changes the grid (it seems that the grid becomes more compressed in vertical direction). That means that it always messes my icons up. I don't know why do the Windows change the grid when I do not change the resolution or just anything that could possibly affect the main screen.

I recently upgraded a Win-XP home system to Win-7 Home Premium. Everything went fine. But I have four system icons on the desktop, two of which I want to keep and two that I'd like to get rid of. The two keepers are the My Computer and Network icons, the two I don't wan to see are the Home Group and Library icons. This machine is the only Win-7 box on the network so Home Group is moot, and I do not expect to explicitly use Libraries any time soon. So the associated icons are just clutter on the desktop. For whatever reason, the two keepers include a "delete" option in their right click menus but the two I actually want to delete don't. So, how do I get them off the desktop? I don't think any of the four were present on the desktop when I completed the installation, and I don't remember what I did to get them to show up.
