Windows 7: game performance drops when unplugged

From that very same article:

Quote:
Removing the battery from the laptop when running on fixed power protects the battery from heat. With the concern of the battery overheating and causing fire, a spokesperson for the U.S. Consumer Product Safety Commission advises to eject the battery of affected laptops and to run the machines on a power cord. It should be noted that on a power outage, unsaved works will be lost.
Furthermore,
Quote:
The question is often asked, should the laptop be disconnected from the main when not in use? Under normal circumstances, it should not matter with lithium-ion. Once the battery is fully charged, no further charge is applied. However, there is always the concern is malfunction of the AC adapter, the laptop or the battery.
If no further charge is applied when not in use, then no further charge should be applied when in use either.

The problem with heat, again, will be challenged more via the use of proper (and enhanced, if possible) ventilation.

The laptop itself doesn't have to be overheating for the battery to get hot enough to sustain damage. When you're gaming on nearly any laptop, but especially most HPs, the battery itself will get hot enough to take damage if it's fully charged, even when the laptop itself is not overheated. It's a function of battery voltage and heat, not the just the fact that it's being charged, even at a trickle.

I understand what madtown is saying, and if you read that article he linked to, he has some merrit to what he's saying, though I would take some as suggestions (removing the battery) more than gospel as I still believe adequate ventilation trumps that one. But if it's an easy step, well...

BTW that's a good informative article in general. Bookmarked

That's not my only source of information on lithium ion batteries... just the most convenient and easily understandable article to pass on

How do you know? Have you looked at how your CPU is running at idle?

At idle, your CPU should be running at full throttle on "Performance" setting under Power Management.

See this post for an example... https://www.sevenforums.com/crashes-d...ml#post1014795

Or this... Wrong clock speed!

What's probably happing is your graphics card is reducing the clock speed of the gpu on battery power. If there is no setting to adjust power management in the ATI CCC, then it's been removed by HP because the battery can't produce enough power to keep it at full speed by itself.. that's not an uncommon situation, and there's nothing else you can do

Hmmm....where is that under CCC becuse I don't see it in mines either (desktop) or is it specific to notebooks only?

So are you saying that the battery will get hotter while plugged in and gaming vs being on battery power and gaming?

Just about every time. Laptop batteries generate their own heat when kept fully charged if it's external temperature gets high enough... and a chill mat is usually not going to make enough of a difference to stop it from happening.
If you've ever left a cell phone plugged into the charger too long and noticed the battery is warm even when it has been sitting idle for hours, that's an example of a battery breaking down due to overcharge, and is caused by current inside the battery itself. The same thing happens with laptop batteries, but usually only when left plugged into the charger after the battery reaches a full charge, while the laptop is in use.
The other reason, is because some machines are designed from the factory to run at a reduced level of performance while on battery power. A 4 or 6 cell lithium ion battery can't sustain enough wattage to run every component at full power for very long if you have a machine with a core i series, discrete graphics, and a large display.. more wattage means more heat from the laptop. More heat= less internal resistance in the battery.. The manufacturers warn against leaving a laptop plugged in all the time for a good reason.
