Having problems with your Acer Aspire 5720-6661 Notebook PC ?

My Acer 7520 won't power up - no fan - just blinking light

\015 I have the exact same problem with the same computer.\015\012My Acer Aspire 7520 won't power up at all. The power switch just blinks on and off every few seconds. I tried reseating the RAM - no help. I tried taking out the battery and unhooking everything - no help., I took out the hard drive and hooked it up to another computer and can access all the files so I guess it's not the Hard Drive. \015\012It's getting frustrating and I see that many people have the same problem. I wonder if anyone actually got a diagnosis on this problem??\015

Answers :

My acer Aspire 7520 sat untouch for almost 2 years. I would start it and it would continually cycle on and off. I read a fix and it worked. Here it is.

\015\012Put in the battery and press start. Let it continue to cycle on and off and forget about it. When Mine got down to less that 10 minutes of battery life. the damn thing came on I logged in and have had no problem since. It is not a other board problem it is a power supply problem. I am not a computer tech but I know enough about electrical current (as a home builder) and it noever made any sense. something inside the power system needed to be reset and the computer went from one power crisis( not powering up is a failsafe against surge in current) and running out of power seemed to trigger the power unit back to normal. Good Luck! Dave
I would check the power supply. Remove it and try it in another PC if possible.
