Toshiba Qosmio x775

[LAMC07]

I'm having a problems with my toshiba. It loses a charge and then refuses to charge while I play a game on it, such as cities skylines or even the Sims 4. It will also eventually turn itself off. Anyone have any ideas what it could be? It's a Toshiba Qosmio X775 - 3DV80. Thanks in advance!

Sounds like you need a new battery to me.
