Hello everyone,

Recently my X17 R1 started behaving oddly.

After shutting the laptop down (by pressing the Windows icon -> Shut Down), it drains battery by itself over the span of 1-2 days. (I have hibernation turned off permamently so I know it's not running in the background). If the charge was 100% when shutting down, after booting it up again the next day it often hovers around 10% or won't turn on at all until I plug it in. This wasn't the original behavior of this laptop.

The other problem I have is when it's running. All of a sudden, the battery doesn't hold charge anymore (when normally, in power saving mode, with advanced optimus on, setting the screen to 60hz it lasted 5-6 hours browsing youtube etc). Now, at 100% charge I'll get maybe an hour of work and the battery shows 50%. After that, after just a couple of minutes, the battery INSTANTLY (like in 10 seconds) drops to 3% and the laptop turns off.

Is the battery dead, or the board is damaged? How do I diagnose it?
