Hi, I'm unable to find the motherboard number (PPID number) or the board view for this old laptop. My laptop won't start, and when I enter the serial number on the Dell website, it says the number is invalid. The sticker on the bottom is unreadable because it has faded over time. Unfortunately, I'm unable to start the laptop to use the power cell or explore other options.I needed the CMOS Cell & it also seems the Laptop will not start now because of the power switch issue, which is yet to be detected.07-19-2025, 01:56 AM -

The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
