AA 7520G boots only if you press hard next to the touchpad

Hello all.
My Acer Aspire 7520G suddenly refused to boot, leaving blank screen only. No boot logo or anything. However, after googling around a bit, I found one thread with a solution, which is to press hard around the touchpad, and to my big surprise it did indeed work.

So does anyone know what's wrong with the computer that behaves this way? I never found the cause, and before I start disassembling the laptop, it would be nice to know what to look for. (Can't take it to the service as warranty expired a couple of months ago)

Thanks

probably a loose connection on the hard drive cage. this model can support 2 drives, it has a little L shaped board that you can plug 2 sata drives into, and then that L shaped board plugs into the mainboard.

Check for any loose components on the cage, and L shaped board.

Thanks for the suggestion. I removed the entire cage and still the same, should it at least nag about missing HD/board? Time to dig deeper I guess.

Took every part apart, cleaned, checked and secured every connection, and put it back in one piece. Now it doesn't boot even if pressed hard. Great. Recycle bin awaits.

That is not good news. I would of thought just as Michelle if the HDD was under where pressure worked? Now unless you did not plug in tightly or can see some visible damage/problem I am at a loss.

I had this same thing happening to my old Sony VGN-S2HP, had to press hard on the palm rest area sometimes to make it boot. Guess what, I "baked" it! Still working after 2 years since I gave it to my sister.

Does not hurt this time to do some "baking"

cheers ...

So you're suggesting I put the laptop into oven? What temperature should be used for it to bake thoroughly?

Not the whole laptop unless you want to have it for Thanksgiving Dinner instead of a turkey or ham

Search the forum for baking, or jump over to the DELL section. We have many threads and posts regarding the "baking" process, with pics and video and with 100% success so far (as of this post submission).

cheers ...

qhn is this really a GPU issue? It won't even boot? Are you sure what advice you gave? And what part OP should put in the oven? Give another shot at an answer, honestly not booting is not a demonstration of bad GPU? Or is it?

I think OP has a fried MoBo?

No, I am not sure. Just stating what I experienced with the Sony with the same issue as in OP. At this stage we have nothing to lose but giving the baking a shot, and how often a bad (fried) board is nothing but a bad connected/loosed gpu on board?

cheers ...

Hi!,
which side of the motherboard should be facing up in the oven? Or does it matter?

Here is a setup a guy used. Make sure removeable components are taken off ie. memory modules etc. Dont know if this works either, but there are a lot of people who have apparently tried it and had success.

I put the side of the GPU faced down. It was a tip from someone about gravity that would pull the solder down to fill the "gaps". Make sure that you spruce the GPU up at the corners with 4 rolled up aluminum balls. Kinda putting some counter pressure into it.

Good lucks .. don't over bake it and make sure that it is being left cooling off (undisturbed) before serving. Mum always does that with roasted turkey.

cheers ...

There's a battery onboard I'm not able to remove without destroying the whole connector. Damn it! I suppose it won't survive the heat.
