My laptop Sony vaio (VPCS111FM) recently started giving trouble in starting. when i press power button all the LEDs (power,num lock,caps lock,Scroll lock) will keep flashing at every 3 second interval for abut an hour and then laptop starts. some times this time may be less and some times it is even more. i have done the following things but still the problem continues.
1. Battery is one year old and in perfectly working condition ( 2 hours back up)
2. Power adapter is in perfect working condition ( checked by multi meter)
3. I have done power draining from mother board by holding the power button for a minute with both battery and power adapter removed.
4. Recently got thermal paste and stickers replaced by a certified technician ( after this problem got started)
5. checked with fully charged battery, only with power adapter ( without battery) and with both power adapter and the battery.
6. did factory reset of the laptop ( though i strongly believe the problem is not of software)
7. No hardware changes since the purchase
despite all the above my laptop still giving me trouble in starting.
