Hi everyone, so this is a weird problem I've never seen before and I could use some help.
I have a HP Elitebook 8760w and I mostly run it off AC power. I was using it a couple weeks ago, it was plugged in and I got a warning the battery was about to die. I tried fiddling with the connector but Windows would not recognize it was plugged in.
I tested the power adapter with a multimeter and got 19.8v on the connector so that works.
I shut it down and popped the battery out and tried to boot just off the AC and it would not power up. I put the battery back in. Still would not power up.
I took out the battery and the AC and did a power drain. I then booted it just off the AC and it came up fine.
I took out the AC and put the battery back and it's stone dead. Did a power drain. Still stone dead.
I took both out, did a power drain and I put the battery and AC in and it booted from the battery, both the BIOS and Windows don't recognize it's plugged in.
I thought the battery might be bad so I ordered another one and it does the exact same thing.
Has anyone seen this before? I fear the charging IC on the motherboard might be bad.
Any help would be much appreciated. I'm thoroughly confused.
