Battery life of DV6238ea

Hi,

I bought this laptop as-is. I'm finding the battery life to be about 75 minutes - and that is with the power settings on 'maximum life'. Does this stack up, or do I have a dud battery?

Thanks

 

You don't mention the battery size, but I would say 75 mins is too short for a regular 6-cell battery pack. My dv62xx has a 12-cell and lasts about 3.5 hours with wireless on and in a customized high performance power setting. It lasts up to 5 hours without wireless and in a lower power mode.

Cutting those numbers in half for a 6-cell gives you 1.75 to 2.5 hours (about 100 to 150 mins), so I'd say the battery pack is well used or just old.

 

Hi,
I have a DV6175ea with a 6 cell battery at get at most 80 minutes out of it. My battery's maximum charge is now at 51mWh. However, I have also just recently bought an Acer Aspire 5160 that has a batter charge of 44mWh. Amazingly this laptop will run on batteries for 3.5 hours, that is over 200 minutes!
The only differences between the two laptops are:
HP
Processor: T5500
Ram: 2GB
Video Card: Geforce go 7400

Acer
Processor T2050
Ram: 1GB
Video Card: Intel onboard.

My question is how is it possible that there is such a large disparity between the systems. I am no fool and know how to minimise power consumption on the laptops. Using battermon I can see the difference in the battery discharge rate. For the acer it is c.a. 17W and for the HP it is about 35W, this translates perfectly to the battery lifetime. I've undervolted the HP, turned the video card performance down using coolbits, even set the wireless card to least performance. The only thing I can think of is that the general motherboard used by HP is essentially crap eating up power here and there. It is the major flaw of the HP laptop, poor battery life.
Anybody else have numbers they can give about the battery life of their HP DV6000's?
