I checked all the connectors, changed 2 ics near the battery and it
became much better.
when i turn on the unit the first 20-30 minutes everything works fine,
but when the p6 has completely warmed up, everything sounds total wierd...
are there any temperature sensitive parts that I should consider to
change? maybe the power supply..??
btw: when I don't close the lid, everything is ok.
thanks for your help.
