is there a way to make graphics card run on full power even on battery ??

[Elmehdi]

when playing video games or running other demanding software the power supply on my laptop keeps disconnecting and reconnecting which causes the the GPU and CPU to keep switching from full power to normal ,
the power supply is 19.5v 4.7A while the laptop demand is 19.5v 7.7A,
can this be causing the problem ?
if so why did it start just recently ??
since i've been using the laptop for about a year now ,
is there a way to make the GPU runs on full power even on battery ??
please help me find a solution to this and thank you

Looks like an underpowered adapter. The amperage of the adapter should be equal to (if not higher than) the requirement on the sticker on the bottom of the laptop.

do you think if i change the adapter it could fix the disconnecting and reconnecting power problem i'm having??

it might work as supposedly that laptop needs 150 watts but that adapter is only outputting 92 watts.

Most likely. And even if it doesn't, you still need an adapter with the correct output anyway.
