Question about Compaq PC Laptops
I have plugged in my laptop in an outlet (an
electric fan is also plugged in another one). Suddenly, it shut off at the same
time as the fan. However, my laptop can’t be turned on anymore while the fan
was just working again when I turned the switch on. The display light for power
status is also broken but the light showing the status of power from the power
cord is still working. I guess the power board inside the laptop is broken due
to the electricity exceeds the limit. Do you think so? Or do you have any other
If I just replace the power board, will it become working again?
Does it damage any other parts beside the power board?
Thank you so much!
The most likely problem that you are experiencing is is the power supply has failed. The best way of checking it is with a voltage meter and verifying that the output at the small connector matches or is slightly above what is listed on the power supply block. Usually it is a good sign that the power LED is lit on the power block but it does not always mean that it is working!
Replacing the power board inside the notebook /laptop is not something most users can do so it would then be advisable if the power supply does check out ok to bring it to a repair shop for repair.
