Laptop shuts down after 20 minutes. Replaced fan. Now what?
Laptop shuts down after 20mins. Is there anything else to do to try and fix this issue besides replacing the fan?
Before you replace a fan, you should be sure the problem is related to that. Check and log the temps with smt like cputemp, update your bios, check for bad connections between battery and mobo, dc jack and mobo, etc.
Did you clean the radiator when you replaced the fan?
