Take an Acer Aspire 5100, which periodically ( much more as of late) will not boot, and going to the bios to look at stuff, the Hard drive and the dvd bulldoze are not even mentioned... other times it will just boot normally. have windows 7 on this ane.
already tried many things ( re-install windows, install some other windows, change HD, flash bios, re-seat processor etc) lately out of agony I found out by sheer coincident, that if I bend the laptop a lilliputian ( thous bending the mobo), it will recognize all, and get-go just fine. as long every bit I concur information technology this way it will work, as soon as I release it, it will freeze and die on me.
already opened all panels, and looked if there were any cracks on the mobo, but none were discovered.

BTW for some reason the bios says this is an aspire 3100, and the body, and sticker says it is a 5100...
I likewise looked up to sell it on east-bay and see at least 5 of them sell equally is for the aforementioned exact reason...
any one has any thought's?,
anyone can help before i get rid of it?
Thanks.

Before you update the BIOS, take a look at what Acer says the System is... On dissimilar models, this is found differently, merely by pressing ane of these once per 2d every bit shortly equally you depress the <ON> button, y'all will get access to a number of low resolution screens with descriptive technical information: <F1>, <F2>, <F5>, <F10>, <F11>, or <F12>
The screen volition tell you what is the currently installed BIOS. Y'all can and so look for the BIOS update for that computer. It what you lot have is the near recent BIOS, then download and endeavour to reinstall that BIOS, following all Acer directions for doing so.

What y'all describe is constitute too often in Acer computers... simply commonly tin be worked out equally above. If the BIOS will not install over itself, use <SAFE MODE> and attempt again.

If you take to curve the laptop and thus the motherboard to go it work, you either have a brusk or an open circuit. It would seem y'all would accept to replace or repair the mobo. Maybe the instance is warped slightly and is bending the motherboard. You could effort loosening the mobo mounting screws to relieve the tension and meet what happens. If that happens to fix it, yous could use newspaper washers to human action every bit spacers with the applicable screws to become the mobo to lay flat without tension. Just a idea.

Acer Aspire Bios not recognize hard drive or dvd

Thanks all for the replies.
Triztan.. This is a laptop, so there are no cablevision connections.
Tmagic & Raybay... Your suggestion looks like a good Idea, and I volition try that tomorrow, and mail service a reply.
Mailpup, your reply seems to exist the right one ( I REALLY HOPE SO,,) I volition try to open up all the screws belongings the MOBO to place. The laptop in general seems to exist straight and not bent, but maybe loosening it upwards will help.
Looks like this is a common problem with this Acer as I have seen a few of the aforementioned model sells for fleck on e-bay with exactly the same problem..
Simply wondering if Acer screwed this one up...

Well... Just opened up the whole lesser of it, and released the screws... looked at everything, and could not see annihilation wrong... Noticed that the cmos bombardment was replaced at some point in fourth dimension ( weldings are not factory fabricated) and decided to place some strong hold on information technology, and what da ya know.... It worked... Laptop is at present fully operational and starts and works just fine.
Looks like in that location was a lightly loose connection on that cmos battery, and when I bented the mobo it made a good connectedness on it..

Cheers all for your input. I hope other people with the same problem get it done.
