CMOS battery replacement

[Looplondon]

Hi,

I’m 99% sure my CMOS battery is dying - I consistently get time drift - as in the clock stops at the time when my laptop is shutdown. When it’s asleep it doesn’t seem to drift at all until I guess it runs out of power if I leave it unplugged.

No boot issues yet but that could maybe start to happen.

I spoke to PC specialist and they sent me the attached image of where the battery is to replace it.

Does anyone have a guide on how to do this? I’d like to maybe do it myself as it’s a cheap part to get off Amazon from what I can see.

Thanks!

The actual battery would look like this on a laptop

They only cost about £4 or 5 on Amazon or somewhere, not expensive to replace.

From the video, my guess is the battery is running off that red and black cable in the yellow circle that then hides behind stuff. Normally they wouldn't be reliant on having to dismantle anything, so I'd start there. It may just need that white ribbon cable temporarily detaching which is simply a case of lifting a little catch on the cable housing which will free the ribbon.

But the battery itself just plugs into a little 2 / 3 pin connector where the red and black cable terminates on the left, it's not a big job

No video just that photo unfortunately - I was hoping for a video guide but haven’t managed to find one on how to do it.

Do you need any specialist tools? (Bar a screwdriver)

Sorry, meant photo, no idea why I said video.

Should only need a micro screwdriver.

If you want a link to a battery, this is the kind of thing:

It would probably be best to remove the current one and be sure on the pinouts before ordering one as sometimes they can be different for different models

If you want to be 100% sure, contact PCS and ask them to send you a link to one they know is suitable.
