Preliminary inspection

The battery is a bit worn out and has swollen.
I need to get it replaced ASAP.

Comparison: old vs. new. The one on top is thicker because it’s swollen, which almost damaged the screen.

Putting some fresh thermal paste on the processor to replace the old stuff.

Screen glued with T-7000.
And while we’re at it, we’ll put on a new screen protector.
