Yep battery remains good after power removed when ONIt's clear that there is a problem when it's on the battery. Does the machine work and show normal drainage when you disconnect the battery? Or does it shut down quickly?
in command prompt (you may need to be in command prompt admin mode for this) type powercfg /batteryreport and press enter. It should make a file. Then go to the location shown and open it. Please copy/paste it here.
I remember looking in the bios for something similar but it was rather basic. Will have another look.You are looking at either the lcd or the board not supplying the power to the LCD... or a simple case of the settings set to low. Can you go into the BIOS and look for anything that says LCD brightness on battery?
If that is a fail, then search for and open the Intel HD Graphics Control Panel. If you have that try Power-->On Battery-->Disable Power Saving Technology. Move the slider to Maximum Quality
