What to do when a laptop turns ON but there is no display?

The table of voltage rails is available on the second or third page of most schematic files. This table is very valuable for repairmen because it shows the presence of different voltages on the motherboard in order of priority. Table of voltage rails can be very helpful for repairing.

Although we had already presented lots of interesting videos on the importance of voltage rails table, in this video, I repair Lenovo G50-70 laptop which turns ON but does not display image on the screen. I used the table of voltage rails during troubleshooting and repairing this laptop, and using the voltage rails table, I performed volt check on the ICs, found the damaged component and solved the problem.

Great video, excellent!!!
This is a very important topic for me and it was well explained. However, how should I proceed to check power voltage rails in
cases where there is no official voltage rails table on a schematic?

It's been two days that I took the 1 year package, a bit disappointed because it didn't match the information that the maximum download limit was 15 times, but only 4 video downloads after that it couldn't be helped with the information that the maximum limit was already.
