better battery life out of a laptop

<< < (2/6) > >>

Ath:
Sound like the cpu and mainboard are the next biggest power consumers, after the screen and hdd, so changing only 1 factor is pobably not going to gain very much.

mouser:
How can such a modern laptop not support ssd drives?
Reading comments it seems like it does support ssd.

It has SATA 2.0, which has only very crude NCQ support, and no TRIM feature, meaning any SSD I put into the thing would not work fast, and also would wear out much more quickly than otherwise :(

Wasting limited write cycles to non-optimized writes...

I have this huge laptop with a smallish battery and a not-so-mobile cpu. Therefore I get 2-3 hours of use on a single charge. So I'm trying to be creative with increasing battery life with it. ...

What is the laptop description and model please? Otherwise, you rather leave us in the dark.
As a long-term laptop user who has had to face up to similar challenges over the years, I might be able to offer some assistance/suggestions, but it always helps to know about the laptop one is dealing with first.

@eleman,
1) I know I *hate* to lose even 15 mins of work, so I would think about the amount of work-time that you could live with losing, and make sure your work gets saved somewhere within every x amount of minutes.

2) Is the battery easily removed? Consider getting a second one?

3) Look at the software on the machine, and what uses up the most CPU and/or RAM -- see can you stop/uninstall some of that.
