Here are the possible reasons for ProBook 6545b to shut down suddenly:
- Power supply
- Overheating problems
- Virus attacks
If your ProBook 6545b suddenly shuts down, it could be because of a break in the power supply. If the laptop is plugged into an outlet for power, check to see if the plug was pulled from the socket and make sure that the cord is suitably connected to the computer. If the laptop is running on battery power, then it is possible that the battery is drained and no longer has enough power to run the laptop. A simple recharge of the laptop battery should fix the trouble.
Computers often shut down because they are overheated and this could be a result of several underlying problems. A malfunctioning fan could be the cause for the processor's excess heat and if the fan is turning too slowly or not at all, it might not take long for the temperature inside the computer to reach a point that would cause it to stop working and shut down. In these cases, a fan motor might need to be replaced, which could be done on your own or by taking it in to a computer repair technician.
Some computer viruses could also cause the sudden shutdown of a computer. These destructive programs could be picked up online from those websites that are not trustworthy or from downloading details contained in spam emails, among other sources. If you think that a virus might be the cause of your laptop's shutdown problem, run a virus scan on the system to find out if any exist.
