Razer Blade 15 2019 Shut down

Hello, I removed my battery due to swelling and I'm planning on replacing it. However now my laptop shuts down as soon as I play games for longer than 5 minutes. I reset the nvidia settings to default and the synapse as well. Also I set the laptop to balance power usage as I'm assuming it's the cause is undervoltage. Could you tell me what the potential issue is and how can I fix it until I get a new battery? Thank you!
