lately when pc went to sleep it would not wake up unless i turned the power off and then turned it back on again, then the other night i turned it off and now it will not start at all, at first the light lit for a few seconds then went out, but now there is nothing at all, just no power.The pc is a Medion desktop MT7 447G, about three years old.
View 3 RepliesI'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?

View 1 Replies View RelatedOver 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.

View 3 Replies View RelatedMy 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.

View 1 Replies View RelatedI have updated my bios from f5 to f8k (latest version downloaded from gigabyte)the reason i have done this is because i want to upgrade my cpu to a phenom 2 955\965 and the latest version allows am3 cpusi have downloaded the latest version,upgraded the first time with @bios from windows (i know that was not wise but i didnt knew at that time)-restart--Computer didnt boot.Cleared cmos,entered bios -qflash- installed the old bios,everything back to normal.After that i tried upgrading to newest version with qflash.Upgrading went fine,restarted,loading factory settings in bios,rerstart,loading os,cpu-z showing the new verrsion of bios - f8k.the big PROBLEM is that every time i unplug the power cord from the psu,or just hit the on\off button on the back of the psu,the computer wont boot anymore.Fans come on,hard drive comes on and the cdrom is making a sound as the system would restart over and over again.IF i clear the cmos with the jumper,computer boots,everything is fine, but after power is cut it wont boot again until i reset cmos.I flashed bios again to the old version(f5) and the problem dissapeares.After that i tried flashing again,I tried every version but they all have the same problem.i teared the computer apart,checked everything inside,left only 1 stick of ram,video card and cpu cooler,still experiencing the same problem.what is the problem? i even wrote to gigabyte,they told me to:1) Turn off power.2) Remove the power cord from the PSU.3) Take out the battery gently and put it aside for about 5 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)4) Re-insert the battery to the battery holder.5) Connect power cord to PSU again and turn on power.6) Power on your system.7) If BIOS can POST, please enter the BIOS and load the fail-safe defaults setting.8) Save changes and reboot the system.I followed these steps exactly as they are written,no joy.I even brought the pc to an "expert" he couldnt help either,he told me i have bad luck.Thats a really bad joke!I really want to upgrade the proc and i dont want to buy a new mobo,i like this very much here are my system specs:phenom 9650 with zalman 9700 ntgigabyte 750a sli mobogigabyte gts 450 (planning to add a second one)2x 2gb kingmax 1066seagate barracuda 7200.12 - 1 tbarctic cooling fusion 550r - 500w,550 peakaerocool modern-v fan controller,3 fanswindows 7 ultimate 64 and windows xp 64 edition (i'm using it just for the horizontal span when i game,i have two 24" monitors)mobo and bios url...

it worked perfectly well till i installed windows7, it still works, bt the picture quality has really reduced. i get better picture quality in windows media player. is there a way to make this work well>?
im back with some more and probably annoying questions, I would like to use something like the link bellow but the description states that (When using in conjunction with a fan controller / motherboard header, be sure your controller can handle the total power of the combined fans) so that got me a bit confused, I understand that I add up the watt on the fans, but how do I know how much my PSU and the cable can handle? I am planing on using a molex to 3 pin connector that comes with noctua fans, could I use 2 of those on the same cable to then add the splitter to, or do I want to use 2 cables and use 1 molex to 3 pin on each cable? I am using a Corsair HX650 PSU and I tried looking at their site under specifications but that info made no sense to me

View 2 Replies View RelatedI've had Win7 for a few months now (thanks to MSDN Academic Alliance) but I've just recently started having this problem. I'm running Win7 Professional on my HP HDX16 laptop. My laptop basically runs flawless when plugged into AC power. When I unplug it, however, CPU usage skyrockets to 95%-100%. I managed to look at the task manager one time at noticed that it isn't necessarily one process that is crippling my computer; It's more like 4 or 5 programs that run around 20 CPU and the rest of the processor is used by various other programs. The process hogging programs vary sometimes, but it usually includes audiodg (audio device graph), mcshield (Mcafee), and a few other svchost (usually Win Defender, Win Firewall and AudioEndpointBuilder). I have the IDT HD audio card for those wondering (and all of the latest drivers from HP).

View 5 Replies View RelatedMy computer will not shut down with the "shut down" command. It goes to a screen with message "shutting down" then just sits there. I need to power off manually to shut it down. Once I reboot I can then shut down properly. But after some time of normal use I can't shut down. Are oine or more of my programs leaving some residual piece in place that doesn't stop when I close the program?

My laptop was working fine until recently when I installed a new SSD (I used an optical bay caddy). The SSD works fine, and actually everything is fine except for the fact that after I shut down the computer it does not power off automatically (I have to hold down the power button for a few seconds). However, when I start it again,Windows does not complain about not being shut down properly, so I guess that it manages to do so, it's just that the power is not cut off. I should also say that neither restart, hibernate or sleep work. The result is the same, with the mention that for hibernate and sleep Windows does complain when rebooted (which is natural for sleep but I don't understand why it happens for hibernate).
The problem starts during the Windows installation, when it gets stuck on reboot.However, I can power it off manually and start it again and it all goeswell. should also say that:- I use Windows 7 64bit with SP1- the laptop is an ASUS K53SC- the SSD is a Corsair Force 3 60GBThe things I have tried so far are- I tried a different version of Windows 7 (on 32-bit)- I tried updating the BIOS (turns out I had the latest version)- I tried disabling the SSD or uninstalling its driver from device manager- I tried disabling all devices that could be disabled from device manager- I tried closing all services before shut down (from task manager)- I tried selective boot (from msconfig) with all services disabled
I have 2 computers here. One is a E-Machines, and the other is a custom built. Both units as soon as you power them on, they go thru the boot up process, but anywhere from 2 to 10 seconds later, the unit turns off. I've tried swapping the ram and the power supply. I have disconnected the keyboard, monitor, mouse and speakers with no change. Both of them developed this problem over night. They do not stay booted up long enough to get into the setup or to even try booting from a DVD.
