Huawei Phone Not Turning on

May old Huawei phone ako, Nova series, na ginagamit sa light gaming, watching video and others. Yesterday biglang nawala volume. When I turn it off, hoping na a restart will fix the issue, ayaw na mag on. Even plugging the charger walang effect. Anyone experienced this? Any solution?

Tried pressing for few seconds the power button, power button+volume down and power button+volume up, nothing happens.

Any suggestions is appreciated. Thanks.
