If it ONLY happens when it's unplugged, it's either the GPU doesn't get enough power (somehow), or the batteries going bad. Try messing with performance settings and changing them from power saving to test the former, and if that doesn't change anything try ordering a new battery

If you can do get another battery to test with.

Many laptop backlights don't work off the battery directly but will increase the voltage (sometimes actually quite a bit higher). This is one of the things that can die and make screens stop working. Signs of impending failure of that can be this sort of flickering.

Other options include if you are moving the screen to take the power out (common for one of those back powered ones) then the moving it can tweak the ribbon and cause this, or said power lead adds that little bit of stress to the motherboard (in most laptops with back power or side power at the back it is but a few mm from the screen ribbons) to have the connection come good. If you turn it off, or pull it if your sockets don't have switches, at the wall that can also help diagnose this one.

If power decreasing modes (on the flip side what happens if you stress the CPU in this mode) lessen it then it is more likely to be the battery struggles to put out enough current or voltage for the inverter section.

this laptop really is a ticking timebomb but im gonna try to make it last

the other day i have my lappy plugged into my tv and had the lappy screen turned off.... i ran it on battery and it held a charge quite well... but when i switched them back i could not even see the screen at all on the lappy untill i plugged it in

UPDATE: I got the battery and installed it... I'm letting it charge overnight but it is the same thing.... I really don't know what to do next.... Ould it be a display issue? Or is it somthing worse than death... I'm really stuck and don't want to say oh well to my main rig
