BIOS Password Acer Aspire 5610Z

I dont remember to have set a password on my BIOS on my Acer Aspire 5610Z. But I clearly have some time. I need to reset it. How can I?

I am having problems with the laptop rebooting every now and then. How often it reboots and when is very random. But it seems to react to vibrations/movement(not always). Even tapping on the keyboard of the laptops seems to make it reboot some times. Other times it cant get through the boot process, always rebooting. But it never reboots before it starts to load the OS from the disk. I can shake it every way I want as long as it is standing in BIOS, or waiting on a prompt for safemode or not.

So I am guessing there is something wrong with the harddrive, orthe OS is somehow damaged and the shaking is not the real problem.

Any advice? If I want to reinstall the OS, I have to change the boot sequence in BIOS. Need to reset the password to get there.

Like you said, if you removed the RAM(all of it0 and then started the laptop, and it made no sound , I can bet you have a bad motherboard. Final.
 
No more TS required.

Normally when you forgot your Bios password simply remove your bios battery for 5 seconds and plug it in again. This can be done quite easily on a desktop. But for a laptop if you are not familiar with computer then i recommend you go to acer service center and they will do it for you just in 5 minutes. If you want to do it yourself, Well if i remember correctly on the acer's the bios battery is accessible under the keyboard.

On the back of the laptop remove the battery and any screws under it, if you look just above the keyboard there's a seperate piece of plastic now remove any screws on the back that could potentially screw into it and remove it (Normally there are clips as well and sometimes you have to slide it either left or right first). Then there's normally a screw holding the keyboard in normally located in the center and 'sunk-in' deeper than the rest of them remove that and the keyboard should lift up, careful its still attached via a zif connector, remove this by pulling up the little tags at the edges of the connector pulling it out (should come out easily) then you looking for either a single cell battery or a black thing in the shape of a battery with a black and a red wire coming out of it.

Thats how you get to the battery.

I would recommend trying standard passwords and see if it helps before screwing:

One example is:

but you'll find many more using google and the words 'default bios password'. Because I can not try it with your computer, I can not give you the right one.

I have opened the laptop and I am looking for the battery. It does not seem to be under the keyboard. Take a look at the picture. There is something that might be a battery under the laptop(not taling about the big battery that is normally accessible). But that "thing" looks like it is stuck.

I would suggest taking it to the service / give a call to your dealer. He had set a bios pwd on my laptop which he later provided to me.

If you can provide proof of purchase (or if you are really good a cajoling people), call Acer Tech Support and ask them for help.

I will habe to take the laptop apart again, can do that tomorrow. Starting to think the hardduive is not the problem. Now the laptop is rebooting on random anywhere in the boot process.

well, it could be a million things. starting from compound on the CPU to your RAM or even the OS; even the temperature since it doesn't reboot on bios and only after booting process.
when you said tapping on the keyboard makes it restart sounds like a hardware problem anything than the HDD. did you talk to acer?

To solve your BIOS password poblem jsut simply update the BIOS from the below mentioned link;
http://support.acer-euro.com/drivers/notebook/as_5610z.html 
Now the question is qhat is making your laptop re-boot/restart?
Ans: remove all the memory from laptop, and listen if you can hear beep codes/sounds. If no, simply replace the MOBO. If yes, Then place the memory one by one and see if one is causing this issue.
Remove the Bluethooth card, wireless card, as well, if possible reseat, CPU once. Check if this is happning in SAFE MODE as well. Try formating and re-installing the OS once, still the same issue. I recommend you go and replace something (HDD, MEMORY or any card, this cannot happen if MOBO is bad, as it wont, past POST.

The link at http://support.acer-euro.com/drivers/notebook/as_5610z.html to the bios update is broken. Also I guess I have to boot from a cd or a diskette station to update the bios. I do not have a diskette station and I cant change the boot sequence, since I cant access trhe bios. I also cant install a new OS because of this.

Replacing laptop motherboards are no issue? Easy to get? I guess I have to have the right model. I will try the elimination method on the hardware as you suggest. In the mean time, here are some pictures of the back of the laptop. I guess it will be hard to see, but there looks to be a battery thingy there under some plastic. But it looks like it is solded stuck or something. Maybe not a battery.

Could not reach any support here in this part of the world yesterday.

:) did you take that shot with your phone? :)
can't see a damn thing :)
try taking a better on pls.
btw, next to the battery there should be a jumper; you don't need to take out the battery; just short circuit with the jumper for 5 secs and it will reset the bios.

Have not seen any jumper anywhere. I took out all the RAM and started the laptop. It didnt make a sound. Tried to fit the RAM sticks one by one, there was no difference between trhem. The laptop reboots any time anyway.

Pictures are very unclear ....
Usually internal battery is located directly under the keyboard.
On some laptops, the main battery is also used as the CMOS battery. Try removing the battery while the machine is not plugged in to AC. Wait about 15 minutes or so. Put the battery back.

Also for some laptops, the battery is under the main battery. Take out the main battery and you should see a small round battery,with most probably a yellow plastic around it.....

I would love to use http://www.cgsecurity.org/wiki/CmosPwd but cant boot my laptop :) or anything else since I cant get into the BIOS.

The shop that sold me the laptop 2.5 years ago adverticed it as:
ACER AS5613ZWLMi/Core Duo T2080 15.4"CB 2048MB(2*1024) 160GB DVD-SM WL 0.3MP Orbicam/VHP

I guess ut is a T2080 socket? Maube I can reuse it somewhere?
On the other hand, it seems as if the issue is either the motherboard or the harddrive,.The OS cant be the problem when the reboots sometimes happen before the loading of the OS.

Did you try what I suggested - taing the main battery out ?
Also a question: Do these reboots happen when you are connected to AC or on battery ?
+ take out the ram and clean the metal parts (that you stick in) with alcohol.

itniflAuthor Commented:
The reboots happen no matter if the power comes from the battery or from AC with the battery out. The main battery is always out when it is not recharging and I am using the AC(no need for it and having it in when there is no need just weares it out).  

I can try to clean all the connectors with alcohol. But later. I have spent 2 hours on this today already :)

Yes. It wouldn't surprise me if it was the motherboard. Where can I get motherboards for laptops, or with the socket required in my case(not sure what is the socket type for ACER AS5613ZWLMi/Core Duo T2080 15.4"CB 2048MB(2*1024) 160GB DVD-SM WL 0.3MP Orbicam/VHP, I guess it is some kind og custom mobile laptop type of socket).

What do you mean by socket, are you mentioning about Processor socket? No machine now comes with Slot in, if you can get the serial no# of the MOBO then you can have the exact spification as well, I hope Acer Support can give you the exact information. Or may be the site itself.
