Hi there,

This problem bothers me and i can't figure it out, i have an acer predator 17 laptop i7-6700hq with gtx 970m.
What i've had to do is limit the cpu to 90% maximum processor state and use better performance power mode,
just so it does not shut off. I don't have a battery that could be a problem, temps never hit above 60c.
Is there something that i could do to fix this problem?

Isn't this the second time this discussion came up?

Edit: I guess you are a new user? I thought there was a Marko (or something similar) who had a very similar thread a month or two ago.

I'm not familiar with that specific laptop, but with certain laptop and power-brick combos, a laptop can sometimes use more power than it's power brick can actually supply. When that happens, the battery would typically fill the gap. If this happens while you don't have a battery, then your laptop will shut off.

I work with a lot of Dell laptops and I see this frequently. Most Dell laptops use a universal power plug. Sometimes a laptop might come with a 240w primary power brick, and a secondary smaller "travel" power brick that is in the 65w-180w range. The smaller brick is convenient for traveling but will cause the laptop to dip into the battery sometimes even while plugged in. I also see this when people are using their USB-C docking station to charge/use their laptop, since it won't always deliver as much power over USB-C as it gets when a high-wattage power-brick is directly attached.

So I would either get a new battery, or see if you can find a compatible power brick with higher wattage (same connector, same volts, more amps).

I was thinking temps or too much power demand from parts myself.

I bought a new power brick 240w, I think the old one was 180w.
