Step 1>>Try removing the battery, cmos battery and discharging. Re-install later and then test if it works.
Step 2>>Replace memory and test if the problem is solved.
Step 4>>Re-sit the processor and confirm if the problem is solved
Step 5>>If all of these steps fail, consider replacing the system board or having the laptop checked at a hp repair center.
