I have an Asus F9Dc-A1 that I bought in 2007 with a Turion 64 X2 TL-56 (dual 1.8Ghz @ 31w TDP). The battery life on it has always sucked, even after I got a larger 5800mAh battery.
I'm attached to the little guy though so I started thinking about buying a 6600mAh 9 cell battery for it but decided that I should look into other options first, like maybe a lower power CPU...
After some research I've settled on the Athlon 64 X2 TK-42 (dual 1.6Ghz @ 20w TDP) or the Athlon X2 L310 (dual 1.2Ghz @ 13w TDP, still 64bit) as parts that should fit in my socket S1G1 platform.
My BIOS is from 12/12/08 which I think is after the TK-42 and before the L310 came out... I don't have a problem running it as an unidentified CPU but I don't want to wreck it either if the mobo doesn't know what to do with it...
So what do you think? Should I go for it? I haven't upgraded a laptop CPU before but it looks simple enough from a physical standpoint... Do you think it will help my battery life much? Which one of the two options would you go for? Thanks for any insight or advice.
