My loptop won’t turn on when i press the power button, only a blue light light on and a black screen
Hi, Can you hear the or feel (place hand near exhaust vent on the underside of the laptop) if the fan is running at all? If the fan is running try connecting an external monitor to the laptop’s HDMI port and check if there is a display showing on it at all. Press Fn + F5 together to toggle through the display options of laptop only, external screen only and both on together. Note: A TV can be used as an external monitor as long as it has HDMI inputs and that you have the appropriate HDMI cable to connect the laptop to the TV. If the fan is not running try a power refresh and see if that resolves the problem: Disconnect the charger from the laptop (if it is connected). Remove the battery from the laptop . Here’s a link to the ifixit Packard Bell EasyNote TJ65-CU-030GE Battery Replacement guide that shows how to remove the battery. Press and hold the laptop’s Power button for 30 seconds and then release the button. Reconnect and switch on the charger to the laptop (leave the battery out at this stage) Try to turn on the laptop. If it turns on and there is a display allow the laptop to boot all the way to the Windows desktop. Allow the HDD activity to settle and then turn off the laptop in the normal manner. When the laptop has completely shutdown, switch off the charger and disconnect it from the laptop. Reinsert the battery into the laptop. Reconnect and switch on the charger to the laptop. Try to turn on the laptop. If it turns on and there is a display allow the laptop to boot all the way to the Windows desktop. Allow the HDD activity to settle and the check the charge status of the battery. If it is charging, allow it to fully charge before switching of and disconnecting the charger from the laptop.
Hi @Peter Bailey Bit confused. Which PC now failed? The original or the new one? Why did you swap HDDs? Did the new PC work with its’ HDD? If it did but not with the your original one there may be a software problem. What OS is installed? Can you start the PC without the HDD connected? Have you tried a power refresh? Most motherboards have a CMOS battery (usually coin cell but maybe in your case, not cannot even find a user manual for your model) See the procedure in the Most Helpful Answer above.
A dead laptop is hard to diagnose but still, you can perform a series of test before you consider a service centre visit.
