Hello,

My Lenovo ThinkPad screen won't turn on. Fn key light is illuminated as is the red dot above the i. I've tried taking out the battery and draining the power, but it is still not coming on. When I press and hold the power button it continually beeps until it shuts down. Any ideas?

Thanks.
 
Hi,

Please do try these troubleshooting steps that I suggested to others who had the same concern with their laptop.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.

Thanks laptop need. I had this issue today and your troubleshooting tips helped. the power adapted being loose resulted in laptop screen but turning on. Wierd as the laptop CPU turned on but just not the screen. Connected the adaptor tightly and the screen turned on. I should also mention my laptop battery is dead and completely reliant on the power cable.
