How to replace the CMOS battery in a Samsung QX411?

[okrobie]

I can't get the case open for this unit. Is there a trick? Thanks, Jim

is it a laptop?

if so look for any covers on the bottom that can be removed--sometimes the cmos battery is under those so you dont have to take it all apart to replace it

Thanks mcnumpty23, unfortunately in this case the CMOS battery is not under that cover, just the HDD and memory. This is a model of Samsung that has a sealed main battery and I think the difficulty in removing the case cover is related to that. I have removed every screw that I see, and the ODD, but at this point, the bottom cover is not even becoming loose.

The cmos battery seems to be next to cpu cooler, not quite accessible without removing back cover.

sometimes theres a couple of hidden screws--in the battery compartment--though wont be if that has a sealed battery

or under the rubber pads on the bottom--which is a bit stupid as you will have to glue them on again

or under some labels on the bottom usually can check that by running your finger over the labels and seeing if it leaves a circular depression

edit -- and have had a couple where you had to take the keyboard out then under that were screws that went right through to hold the base part

Thanks little_me, those You-Tube videos did the trick. I was being too gentle.
