Hello,
Start the problem, when I plug my Gateway M520s Laptop to AC car adapter. When I press the power button second after power indicator LED Blinking (manual says LED Blinking-notebook is in standby mode).Unplug the AC cord and remove the battery for 2-5hrs and press the power and F2 for bios setup windows. I can see Bios option after 2-3 minutes shut down itself power indicator blinking again and with black screen. Hold the power for 3-6 sec. to shutdown and press again suddenly power indicator blinking can’t go no more to bios setup. Same thing happen as there is a windows XP boot up disk in the DVD Rom will try to read disk and shut down the few minutes and power indicator start blinking. Does anybody know what’s the problem of my laptop, where I start to troubleshoot?

Configuration: Windows XP Internet Explorer 7.0

Restart it couple of times and once it did go through Bios and stay for 2-3 min and will shutdown itself and turn the LED power blinking.I can hear fan spinning while in Bios windows.It did flash up a blue gateway screen but then power off fast.I'll continue trying to start it and see if I can get anymore information.Any assistance will be highly appreciated.

I'm having the same exact problem. Did you eventually figure the problem out? I realize my battery is dying, but I only get the blinking light problem when the AC adaptor is in. The only time I don't have the blinking power light is when my battery is in and no AC adaptor, but like I said, battery is dying, so it doesn't last long. I'm looking for any help you or anyone else can provide. I've looked everywhere, followed every advice I could find... recalibrating the battery, holding the power button down, letting the computer sit with the battery out for several days, trying to load into safe mode... nothing better.

I have the same problem. Not a battery problem, since I have two of them and nothing changes with a new batterey.

I own a computer repair shop in Orange City, FL and actually come across the same issues all of the time. Sometimes the computer has a solid red light for the battery light, the processor is bad or burnt out or it can also be the heatsink that cools the processor, if the computer senses it is getting to hot or something is not working properly it will just shut down.

If the light is just flashing and there is no video post it is usually the motherboard or something shorting out the motherboard. I have fixed a couple of them by removing and replacing the wireless card.
