You're very welcome.

 

Glad the experiment worked and that your notebook is performing better.

 

Maxing out the memory will also help significantly.

Wow.

 

I didn't think that upgrading the processor would cause a drain on the battery like that.

 

I mean it wasn't that huge of an upgrade.

 

Your old processor and the new one have the same wattage and voltage specs too.

yes but.

 

t1600 uses 7.7w in sleep state and 56w under load.

t3400 uses 9.1w in speed state and 75w under load.

and to be fair the CPU fan is running a lot more so it may be running under load for some reason. it may calm down when i do a fresh install of the OS and all programs

 

one thing i know because of building my pc's is that the max TDP is a total scam as you can see there both 35w CPU's but both use will over that under load.

Very interesting.

 

You know more about this than I do.

 

Maybe the processor has to "burn in" some more, so the new thermal bond improves.

 

If so, the fan should kick on less.

hi,

 

i did a full reinstall of windows, dropped the display brightness to 60%, and dropped CPU usage to 50% when on battery and i have found a massive improvement in battery lift.

 

SSD makes the little old laptop kick ass..

 

ones again i would like to think you for your help with the cpu and ram info, you have been a star.
