I'm helping a friend troubleshoot their older HP laptop (model HP 17-by1061st) that recently started acting up. The issue began when the laptop wouldn't run unless plugged into the charger, so we decided to replace the battery with a new one. However, after the battery replacement, the laptop won't boot past a few error screens. Here’s the sequence of what happens when I try to start it:
Here are my questions:
- First, I get a BIOS error 502 (BIOS checksum invalid).
- Then it shows error 601 (Battery capacity reduced).
- After that, it displays a "Critical Resource Unavailable" message and restarts.
Here are my questions:
- What pins should I check on the battery or charger to verify if the voltage is up to spec?
- Is there any other method or troubleshooting step I should take to resolve this issue?
