    my lap top (a gateway bought through the hsn) over the last few weeks suddenly looses all power. sometimes it wont restart unless I remove the battery for a few minutes along with plugging it out from the wall outlet. I cant seem to associate these episodes with any particular action and can't predict when it will occur.

    I have same prob with my M6R Asus, heard them being known for overheating. Mine keeps shutting down unawares so I have just taken it apart and vacuumed the fan. Then I also put new thermal compound between heat-sink /cooper flat wire/ and cpu.

    None of it helped. I turned it on and started working....then it showed black screen with ISO in left top corner ... but this happened for the first time. I switched it off and on .... started working but lasted for like 5 seconds and than again...shut down...and again....Don´t know what to do.

    Maybe it is overheating of graphics but really just guessing, please reply someone if any suggestion.

    I have an acer 5315 that will suddenly just turn completely off, even when the battery is fully charged. I've worked a little with the diagnostic software that comes with the computer but am not able to make use of the it. It seems to happen more when I use the sleep mode when not using it vs doing a complete shutdown. Very irritating problem as it will work fine sometimes for several days and then all the sudden Bam, total power failure. When it is turned back on it gives the option to boot in safe mode but I have all ways selected to boot up normal..

Hi,
Is the battery holding a charge? If the battery's no good, then I'm thinking the power adapter plug in has loosened from the motherboard, not completely, but enough so if moved just right, power is lost.
If the battery IS good, then you need to vacuum or blow out the fan/heatsink vents. It would be best, if this is the problem, to have it cleaned by someone with experience.
Let me know about if the battery is charging or not.
Good luck

Netbook Screen Turns to White Noise after Turning on within 1 Minute

Could be a problem with the flat cable (the connection from video to motherboard) but since your screen starts to fail after a little time could be a problem with the integrated Intel GPU too.
If your model has the second GPU (Like Nvidia Ion) try to disable it and see what happen.
A good test is to turn on you netbook and leave it on Bios settings page to see if the issue is software related or not.
Another test is to hook an external monitor (if you have a VGA or HDMI port available) and see if the GPU is ok.
If the problem is the flat cable you can try to replace it but if you have a faulty GPU and you are out of warranty you need th replace the entire motherboard because normally GPU is part of the chipset and can't be replaced.

Green light blinking very fadley pc will not turn on

Sounds like you might have a partial power supply failure. Try unplugging the power supply from everything. Ther should be a switch on the back that is red and says something like 115/220 just flip that switch over to 220 and wait 5 minutes then switch it back to 115 and replug everything in and then try it. If it doesn't work then unplug everything again and let it sit for about 30 minutes (this resets the power supply) and reconnect the wires and if that doesn't work try getting a new power supply. In partial PCB (Power Supply Board) failures the problem is that trere isn't enough power going to the system to start up so sometimes resetting the PCB will fix it temporary. You should get a new one anyway. that one will fail completely soon. Good luck!

Switch simply wont start up after power failure. Just power led is turned on and nothing else happens. There was a short power failure few manths age and same thing happen. Solution was reseting the switch...

Maybe there was a power surge or spike that damaged the router. But if you unplug it and wait a minute or two, then plug it back in, maybe that will reset it. If it is a router, there's usually a small red button on the back, sometimes recessed, that will reset it and that might cure it.

E machine monitor turns itself off and on

The same thing happened to me today. I was just sitting in my room then i hear a click and the cpu is on it stays on for a while then cuts off. It then cuts on and off with few seconds in between. It then stays in that way cutting and off for about a minite or two and then cuts off completely. A few minutes later it starts again. Also in the time it its off it will not turn on by pressing the power button. Sometimes it completly boots up by itself and then shuts itself down. If I shut it down manually while its on it'll turn itself on immeditaly after. What's going on! Will the warranty cover it? Do I need a new computer?

Lcm-17v8 monitor

Hi,
This is a problem with the cable that runs from your laptop to the monitor.
Or the VGA Output socket, on your laptop itself.

1:) Try using the monitor, on a different PC Or Laptop.
2:) Toggle The LCD/VGA Button on the laptop. ( This should change the display Mode )
Sometimes you Have A fn key, on the keyboard. Press fn And LCD/VGA.
3:) Check that there is no damage to the cable from laptop to Monitor.
If none of the above work, it,ll be the monitor itself. faulty panel or invertor board.
