I am trying to fix an Asus L50ij laptop.
Symptoms: lost all battery, wouldn’t turn on on power cable.
My first guess was the power jack, because the transformer was good. I opened it up but the power jack was OK. However, I found the b4 diode was blown. I got a new diode, replaced it and now the symptoms are:
- Won’t start on power cable only or with a discharged battery in.
- With a charged battery it starts.
If the battery is taken out it stays running. If a discharged battery is put in while on, the battery light blinks.
Any ideas on how to fix this?
