I think schematic available for this model. So you need to check RTC section thoroughly.

Now the next problem is after a few minutes the laptop shut's down. The automatic start problem has been solve by replacing a lowbat cmos battery

I've already remove the Nec/tokin capacitor and replaced with 4 pieces of 220 uf capacitor , measuring its voltage will give me 1.1v maybe the start-up chip is the problem?

I've ealredy clean the laptop

4 X 330uf is suggested instead of 220uf
