Laptop shuts off 2 seconds after booting and repeats..

by andrenapster / July 28, 2009 1:31 PM PDT

Hello all,

When I press the power button on my laptop the green led lights and the fan starts and in 2 seconds it shuts off, and then starts doing the same pattern over and over.

When I push very hard just below the power button, the laptop starts until I take the pressure off. On the other side of where I push is the part in the motherboard that's the closest to the battery, so I suspect something that's responsible for the power.

Btw, it does not make any difference if I run the laptop on the AC or the Battery..

My laptop is acer aspire 7520.

Please help!

Just so you know.

I really must make a sticky post about this. Here goes.

Laptops are made of just a few "parts." I can't write this over and over but will until I make the sticky post.

We have the power brick, display panel, main board, keyboard, drives, cables and the other tiny bits and that is what is changed out when you have a failure. Today, it's how these are fixed.

Your failure sounds like an intermittent connection or device on the mainboard. Price out a replacement mainboard. Acer is the source for the part.

Ok to get this fixed you will first need to press the power button on the PC hold down the ALT key and keep taping the F8 button till the computer reaches the password screen ( no time should pass after you turn on the computer immediately hold down the alt key and keep tapping c8 key)

I had an issue with my Acer awhile back and
by orlbuckeye / July 29, 2009 5:44 AM PDT

I thought it was the motherboard. I called a local laptop store and they quoted my at around 300 for an Acer 9810. Mine was starting up with the Acer screen and then the screen switched to black and hung. The problem turned out to be bad memory and not a motherboard. It happened again an the first thing is did was pulled out a memory chip and it booted. I had an extra 2 gig memory chip so i stuck it in and it's been working fine for a couple of months.

I wish it was a problem with the RAM, it's like the easiest thing to fix plus I would've bought bigger ones.. Happy

But no, I tried to use both of the rams I have separately with no luck. It's definitely something with the power, the laptop doesn't even show me the 1st screen (acer screen) it shuts off before.. I don't think it checks the RAM or anything in that stage.

Has anyone had a similar problem?

Similar problem
by BumTiTTy / December 22, 2009 1:20 PM PST
In reply to: Thanks orlbuckeye..

Mine powers off a few seconds after starting up and goes into a loop for about four times in a row then stops. It does not get to the BIOS. If I keep turning it on, eventually, maybe when it gets warm, it works fine for ages.

Same for battery or mains power. But doesnt loop as many times on battery, hows that for power saving!

I will try some new memory first then the motherboard. I had some blue screen messages before as well.

clean your RAM
by paul1149 / March 8, 2012 3:40 AM PST

I know this is a late follow-up, but I just tried something I had heard of a while back. Take your RAM out and clean the contacts with an eraser. I had this problem on two Acer One D250s, and the common denominator? I had taken the ram out and put it back in. Evidently doing so upset some tenuous connections. Now I've got the machine back

Possiible Solution: Worked for me.
by joejoe930117 / January 28, 2013 11:39 PM PST

I understand that the OP probably does not need this information, but for others that search this problem like i did and need an answer:

Try taking out the Wireless Card. In an HP Pavlilion PC, this was the cause of the problem. There was supposedly a known problem with this that is no longer being taken care of by HP.
