Hi everyone!

 

Last year I bought a second hand macbook 4.1.

It had some obvious signs of missuse: The battery was swollen and the screen was broken. It also didn't had the original power adaptor.

I always found it strange that the fans never turned on even when both cores were at a 100% load for a long time and the temperature never went over 60C.

So yesterday I installed Coolbook and found out that the CPU never goes over 1.2Ghz. I tried to change the settings. but with no effect.

 

Does anyone know how can I "overclock" my Macbook 13?

The idea is of course restore it to it's factory settings.

Are you running the MacBook without the battery....on the AC adapter only?....if so that could be the issue..

There’s one problem with running your MacBook with the battery removed. MacBooks and MacBook Pros automatically reduce the processor speed by about half when the battery is removed.

You can get a new third party battery fairly cheap on eBay. Every MacBook from 2006 through Mid 2009 except the Late 2008 Aluminum Uni and the Late 2009 and 2010 White Unibodies use the same A1185 battery.
