Jet A1,
Believe it or not, yes it does. A good rule of thump is:
A stick of PC 66/100 uses 7 Watts
Two sticks of PC 66/100 use 14 Watts
A stick of PC 133 uses 12 Watts
Two sticks of PC 133 use 24 Watts
A stick of DDR uses 10 Watts
Two sticks of DDR use 20 Watts
A Pair of RAMBUS uses 10 Watts
Two Pairs of RAMBUS use 20 Watts
I do not think it would use that much to make it not wise to up your RAM. If you are running WinXP, 512Mb of RAM is optimal, what are you planning on running on your notebook that needs 1Gb of RAM?
Take Care,
Richard
