Where is the cmos battery?

So, if it is not working i need to replace the main battery in this case? I replaced the main battery about 6 months ago and it did work for at least 5 months. The main abttery also seems to be fully charged and when using the Lenovo support site and making a check of the battery status it says that the battery is working

It stopped working after it has not been used for about a week

Try a power refresh and check if that works by disconnecting the main battery cable from the motherboard and then press and hold the laptop's Power button for a full 30 seconds then release it

See Step.4 of the ifixit battery replacement guide

Then reconnect the battery, reassemble the laptop, connect the charger and check.

If it starts OK after this when you said "....making a check of the battery status..." do you mean you created a battery report?

If not create the report and then compare the Design Capacity value verses the Full Charge capacity value in the report.

For a good new battery they should nearly be the same.

If the Full Charge value is <50% of the Design Capacity value the battery may be faulty. A good battery should hold its charge for more than 1 week

Thanks, I will try this an report back,.

I got this report from Leonvo: (Framgång == Success)
