Sony vpcs1 laptop power on and off repeating - Sony Televison & Video

Can be your power supply over heating. It can damage your PC if that's the case. Also make sure you check your CPU fan and heat sink for dust which will cause over heating of the CPU.

If there is no pause, you may have a power supply problem. This would require an authorized sony servicer.

When you first power up, press F8 repeatedly and it should come up with a menu to select Safe Mode. I hope this helps.

It seems your DC socket is suspect, as sometimes it connects and powers on and at times it doesn't. replacing the DC socket on the motherboard should cure it.

Remove the power cord and remove the battery pack. Wait 20 minutes or so. Restore the power cord. Turn on the power and tap the F8 key repeatedly. Try booting into Safe Mode, then Restart normally.

The problem is your power supply charger, or the DC jack in the laptop, or bad battery. Remove the main battery and see if it will start up, if yes! the battery will need to be replaced, If no! plug charger in the computer and apply side-way pressure on the DC jack "not to hard" and press power repeatedly to see if you can start it, If yes! It is the DC jack that has broken free from the motherboard, If no! It is the power supply or motherboard. I suggest a computer tech

try to turn off the laptop. Remove cables and battery then press and hold the power button for 8 secs. Then reinsert the cables and battery on the laptop. Turn on the laptop. Check if the BIOS screen appears. If it is still wont boot to windows, try to restart the pc and repeatedly press F8 to Boot to safe mode. If unsuccessful, this might be a problem with the memory of your laptop. If you cannot tear down the laptop, consult a technician to tear it down and reseat the memory .. or better call your manufacturer to repair it...

that might be a motherboard problem. your computer requires service
