ram memory vs battery life

[tokelosh]

I just increased the ram on my T40 from 512 to 768 and am noticing quicker battery drain. Does this happen? More memory more juice required? If not I wonder what has changed!
Can anyone enlighten me on this?
Thanks.

Hmm, I didn't really notice any increased battery drain when I went from 512 MB to 1.25 GB. How much of an increase have you seen?

Not so you should notice. If anything it should decrease you power consumption if you hard drive is running more due to swap file.

The battery is now running down almost double pre ram increase.
My new ram card is a Transcend 512M DDR 333 SODIMM CL2.5.
Any one know if this is the cause of the change?

Something is wrong. I got 2gb of RAM in my 2373KXU and get 5 hours on a battery with power to spare.

Something is wrong! Try removing the ram and see if that helps. If it does it is not the RAM's fault but possibly a mother board problem.
