Acer 5552g corrupted bios

[Razeh]

Hello.

Excuse me if I'm posting in the wrong section but I'm in need of help and I'm not sure what to do anymore.

My Acer 5552g laptop died yesterday. It doesn't show anything on the screen and only one led is lighting up: the one that has a little lightbulb icon above. The cooling fan starts for a few seconds but then it goes into idle. I haven't done anything special with the laptop prior to it malfunctioning. I've just shut it down (it told me that some background software needs to be closed first but I was in a hurry and clicked the force shutdown button) and the next day, when I tried to turn it on it started behaving like I mentioned.

I suspect it might be a corrupted BIOS problem even tho I haven't tried installing a new version of BIOS on it. I have tried the recovery mode technique which involves pressing FN and Esc and then powering it on while having a BIOS.fd file on an USB stick but that didn't work. Today I have disassembled it in order to find and take out the CMOS battery but I am not able to locate it.

I have attached some pictures of the motherboard. Maybe you can help me find the CMOS battery. Or suggest a solution.

Thank you very much!

So if my laptop behaved the same when I removed the HDD, is there really a point in trying to boot it up with... let's say... a linux dvd? Not sure if I can find one today.

I am, however still thinking about doing that reset CMOS thing but I'm not quite sure how could I short up those two contacts and in what conditions. Should the laptop be plugged in, powered on, does it matter if the CMOS battery is there etc.

You've already seen the CMOS reset procedure use for the BIOS password reset. It does reset the CMOS in addition to clearing any password. At this point I see no harm in using it.

 

[Razeh]

Yes but that procedure involves removing the CMOS battery. Won't it harm the battery if I leave it on the motherboard? What do you think my problem could be? Hardware failure?

 

[WR2]

That procedure did NOT involve removing the CMOS battery.

 

[Razeh]

Isn't the RTC battery the same thing as the CMOS battery? Check No. 2

 

[WR2]

It's the only battery.
(RTC battery = CMOS battery)

 

[Razeh]

Yes and it says in step 2 to remove the RTC battery.

 

[WR2]

Where do you see that? I see "Disconnect the RTC battery cable"

 

[Razeh]

Isn't that the same thing? Don't want to be rude or.anything. I just want.to make sure it won't catch on fire.

 

[WR2]

You have more info than I do - you can look at your motherboard figure stuff out that I can only guess at.

 

[Razeh]

Well the thing is...it says to disconnect the battery's cable and I think it's for a reason. And since mine is soldered I don't think it's the best idea to do it. Yet again, I have no experience whatsoever with mobo's and stuff like this.

 

[Razeh]

Ok so I tried that procedure and nothing happened. Oh well.

Sadly, no. I tried various stuff, even took it to a laptop repair shop. They managed to make it work for a few days but it broke again.
