Replacing the CMOS battery in this model?

Hello, I actually own the 3542 not the 3541 that I selected but it was the only option and plus they seem nearly identical.

Whenever I boot up the laptop I get five beeps. I looked up the beep codes and apparently that means the CMOS Battery is failing. Was just curious if anyone had a guide? Instructions? Or anything. Even where to buy a quality replacement battery.

Just curious if this solution works. I also have the 5 beeps on startup and shutdown but am a bit intimidated by the disassembly process, have never done it before.

Here is a link to a video which shows how to remove the motherboard in your laptop so that you can access the CMOS battery.

At 2:56 minutes into the video the battery is visible.

I have highlighted the battery location in the image below.

The battery looks to be a standard lithium coin cell type battery. The type number will be stamped on the battery. They are most probably available in supermarkets etc.

Hopefully this is of some help.

Hi @john666 ,

Given that it is the Chosen Solution to the question with 4 upvotes I'd say that it must have resolved the problem for some people. 4 people at least, (you can only upvote once per answer) or perhaps 3, as the OP can upvote as well if they wish. The OP is also the only person (besides the moderators) who can accept the Answer. I am not a moderator ;-)

If you wish to try doing it yourself, my advice is that as long as you take your time, that if you do strike problems to stop and think it through before proceeding with the repair and to treat the equipment with care then you should be OK

You will also gain the immense satisfaction of having done it yourself.

However, if you feel that it is a bit too much for you, contact a reputable, professional laptop repair service and ask for a quote for the repair.
