Verify the power source

If your laptop is not switching on even when its power is being put on, you need to check if the power indicator light on the adapter is on. If the light is not showing, unplug the AC power adapter and plug it in another outlet. This may turn on your laptop.

Check your laptop’s brightness

There may be a possibility that your laptop’s brightness is turned down completely. Here you need to check your laptop’s keyboard. Use the key showing a ‘SUN’ symbol on the keyboard to fix your laptop’s screen’s brightness settings.

Detect the battery’s status

If there is no indicator on the laptop which shows if the battery is connected to the laptop, you need to replace the battery.

Connect your laptop with an external monitor

Look for a VGA connector to link your laptop with another monitor. If the external monitor lights up, the blank screen of your laptop is due to video subset problem which can be fixed by changing the LCD screen of your laptop.


You have successfully fixed the blank screen of your Lenovo ThinkPad T510 laptop, with iYogi’s assistance. Now you can fix the blank screen of your laptop, all by yourself. However, we recommend you to replace your laptop’s batteries to enhance its power backup time.
