Hey guys, beginning to work on board level faults.
Machine is our stock, came in not charging batt. Battery is brand new, tested in another machine as not faulty. In Bios, originally it would say Battery: Health excellent, Charging: Idle, AC adaptor: Unknown
Using different genuine AC adaptors changed nothing.
Opening up showed liquid damage, PU1 was burnt out, and PR823 had rust on it.
Replaced PU1, no change. Replaced PR823, and the symptoms have changed.
Now battery shows as not installed, and AC adaptor : unknown.
I dont believe that either component is wrongly placed after staring at the board for however long.
What IC's are responsible for the detection of genuine chargers? I think thats my next port of call.
Thanks in advance.
