Enter servisan from counter neighbors again (hehehehe), blackberry 8520 with complaints
- The battery is only lasting half a day just a little over 6 hours of standby
- Bb not overheating conditions/short
- Installed new battery are OK still remains as it is.
Once dismantled, it turns out that there are parts that are scorched like the image below. Immediately replace parts from other machines, and back to normal.
The message: don't hesitate to pry the can cover the pcb, if I release the can cover the pcb by using blowers but with caution and concentration (don't look in my eyes) hehehe.
