P72 0271 2102 Errors

[u/Boring_Penalty_1134]

Hello,

My P72 is having the following issues:

1. 0271: Check date and time settings

2. 2102 Detection error on HDDO (Main HDD)

Press Esc to continue .....

After pressing the Esc key, the laptop runs perfectly (boots from the M.2 SSD).

I’ve done some reading and suspect the RTC circuit. The socket where the CMOS battery is connected is supplying 1 volt. Can anyone comment on this? Replacing the CMOS battery didn’t make a difference either. Is the P72 still salvageable, or is it not worth the effort?
