Laptop weirdness

Here's one for you. My laptop at work does something weird. If I've
had it unplugged from power for a while, it runs quite slow when I put
it back in the dock while on line power.

It's running windows 8.1 (I know, that's probably half the problem),
has 8GB of RAM and an ssd in it.

If it's fully charged and on ac power, it runs fine, or when it's
running on battery it's fine, just gets sluggish when it's charging the
battery up from a charge lower than 100%.

Any ideas?

Hi
BIOS charge settings? What hardware is it? Battery getting old, if it's
a HP you can press F2 and run a battery check.

If it's an intel CPU, perhaps speed step not working? What
performance stats are reported in Task manager?

Batteries can heat up when they are charged. Perhaps the CPU is being run at a lower clock frequency to minimize the heat build up.

Of course this is just speculation considering the little information you provided, 😉

Re: Laptop weirdness

Does your laptop have different power states? I did a google search
and found someone who was experiencing the same thing with an AMD
processor. Here's what he said:

"I had to change the P0....P7 states, the power states, of the amd cpu.
The problem was, the CPU started to slow down to 1.1 ghz when plugged
in. So i changed the power states from P7 - P3 to 1.9 ghz. So there is
no other power state, which would bring the cpu to 1.1 ghz.
And thats how the problem was solved "

If that's not it, download CoreTemp and see if your processor is
overheading while the laptop is being charged.

Just a couple of ideas FWIW.
