Yes, your system has two different GPU’s one thats part of the CPU chip (IG) and the second the dedicated GPU chip (DG). When you start your system the IG is whats used until it gets to POST at which point the dedicated GPU will engage (you’ll see the grey screen change color a bit).
In your case I don’t think your DG has failed, I suspect your battery is in trouble. Lets first get a better idea on the batteries condition install this gem of an app [https://www.coconut-flavour.com/coconutbattery/|CoconutBattery] take a snapshot of the main window and post it here for us to see [guide|21499]. If you can’t get the app to install directly you’ll need to try using Target Disk Mode. Using a second Mac system connected to yours (in TDM) by pressing the '''T''' key, The other system will need to be restarted using the '''Option (⌥)''' key to get to the Startup Manager and selecting your Mac’s drive as its boot drive, then once installed restart your system so you can get the CoconutBattery output.
If you can, see if you can run the built in diagnostics directly did you get any errors?

Well as I suspected your battery is in desperate need of replacement!
Your battery only has about 50% (fair) of its performance which is an an approximation.
-The real data point is the cycle count. Your battery has 2,358 !! Which is over 1 1/2 times over the true life span of 1,000 cycles.
