Just curious about what can be done to improve battery life (time between charges) in a laptop.
I recently purchased an HP dm4 notebook. Most people and Consumer Reports get up to five hours on a charge. Me? I'm getting maybe three.
Perhaps the fact that the machine is only 10 days old and I use a wireless mouse are factors? I know about power management settings. I left the sleep mode on default to see how it goes.
I can usually squeeze an extra hour out of my laptop by turning down the screen brightness all the way. Also, not sure if HP has this, but Dell has power management settings to turn down the performance of the laptop and get extra battery life.
You could always purchase a 9-cell battery if you want extra juice. I bought an off-brand one for my laptop and it has lasted longer than the OEM Dell battery.
What is your brightness on? You may have the highest brightness which will drain the battery quickly. What "tasks" are you doing? They may be just doing plain internet research. Are you playing games?
you can run a laptop on ac until you pull the ac cord from the outlet
^ Tee hee! (But that is the correct answer.)
OP, you might do just as well to get a bigger battery. I have some Toshiba Satellites sold in 2009-2010. I have a 9 cell in one and 12 cell in the others. Much better than a 6 cell. I never could achieve the touted 3 hours battery life with the original 6 cell battery, ever. Not even close. Not even if I throttled back everything and kept the screen so dim that I could barely see it.
