Gateway laptop shuts off while rebooting


Mar 20, 2016
Hello folks,

I hope someone could share some knowledge to fix this issue. I tried to service my gateway laptop by cleaning the fan. I had to basically disassemble the entire thing. Cleaned the fan, replace the thermal compound and reassembled the laptop. When I turn it on, it came on and ran the scripts but when the OS (Windows Vista) the laptop just shuts off. I haven't tried the ram memory method yet and not sure it could be CMOS battery could be it.
Any help will be greatly appreciated

Please do try these troubleshooting guide that I suggested to others who had the same concern.
- Start by removing the battery and boot it up with just the AC adapter connected and see if it will boot up normally.
- Next is to test the AC adapter if it's supplying enough voltage or try a different AC adapter that has the same voltage.
- If it doesn't work proceed with reseating the RAM's, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still shut down after doing all these steps you may need to open the laptop again and make sure everything inside was properly connected into each port.
- Also do make sure that the heat sink of the CPU is well placed on top of the CPU because it can also be that it's not properly seated and overheating.
