Helping people with computers... one answer at a time.
Power settings in a laptop will be in the Control Panel and also in the BIOS. Changing them requires checking both areas.
Hi, I've noticed my old laptop when connected to the internet runs slower when using the battery compared with AC power. Most noticeably when watching videos, YouTube etc. I've tried googling for a solution and have changed some settings in power management to try to compensate, but to no avail. I even downloaded a program called 'Speedswitchxp' which claims to solve this problem but it hasn't. As soon as I pull the AC power from the laptop, the screen noticeably dims, even when battery is fully charged (brand new battery, by the way). It's an old Dell Inspiron 1000, running Windows XP.
In this excerpt from Answercast #37, I look at the reason for power settings in a laptop and how to reconfigure them for more power.
The short answer is, "I'm not at all surprised."
Many laptops will intentionally cut down their power usage when they are not plugged into AC power.
Normally, there are power management settings you can control in Windows, in the Control Panel under Power Management. Sometimes, there are additional power management settings that are not actually available through Windows, but are part of the system BIOS instead.
What I would recommend you do – if you are certain that you're willing to trade off a shorter battery life for more processing power when you're not connected to power – is:
Go into your computer's BIOS and look specifically for Power management or APC (Advanced Power Management Control, I think it is) settings that may allow you to tune exactly how the computer reacts to a lack of landline power: of AC power.
The battery will need to be recharged more frequently, in that case. It won't last as long, but it should give you the power. It should give you the processing power you're looking for.
Between the two of those, you should be able to tell the computer to go
ahead and use as much as power as it needs – whether it's plugged in or
