Device fails to power on due to insufficient charge.
Device fails to power on due to insufficient charge.
Hello, I'm trying to understand what's happening. I had my laptop dual-booted with Linux, but storage was getting low. I removed the Linux partition and merged it with my regular drive. Then I switched to using an external hard drive for Linux, which worked without problems—just a slower boot time because of the external drive.
But when I switched back to Windows, my laptop wouldn't charge properly even though it was plugged in. After some time, the charging indicator appeared. Over time, I noticed that despite being connected, the battery was actually decreasing instead of increasing. This was unusual since before I could charge and use the laptop simultaneously. I changed the charging cable, but the problem persisted.
I looked online and saw suggestions to open Device Manager, update or uninstall battery drivers, and restart the laptop—tried all that without fixing it. When I shut down Windows (not just closing the lid), the battery would charge again.
I'm a HP Pavilion DV0xxx model (¯\_(ツ)_/¯) and this is really confusing. It seems like the battery issue is happening even though it's plugged in, which is strange because before it worked fine. I don't want to reinstall Windows.
This outcome is also present on Linux, the charging symbol shows up yet the device doesn't power up.
It might be A: a faulty charger or one that deteriorates, or B: a defective or deteriorating battery. Try removing the battery and test if the computer runs fine using only mains power, excluding the external drive. After turning it off, reinsert the drive and perform a cold restart. If performance drops, the charger is probably the issue. Doing this twice suggests the external drive could be the culprit if problems occur solely with it connected. As an extra check, leave the battery fully drained and powered off for the night, then charge it overnight without the drive. If it doesn’t reach full capacity, the battery is likely bad or failing. This approach is being taken just to be sure.
