I have a Razer blade 15 and whenever it's unplugged it turns off. BATTERY IS NOT SHOT!

So I had my laptop outside with me yesterday playing music, so I know my battery isn’t shot, I turn it on this afternoon and unplug my laptop and suddenly it just turns off, as if the battery is shot but it’s not… I just used it the day prior just fine. I power it back on and the battery says it’s still fully charged… I thought it might be a driver issue so I updated everything including the drivers, didn’t work, the moment I unplug my razerblade 15, no matter what I do it just instantly powers off does anyone know how to fix this issue?
