Envy 15 @931mhz

Hii,

It seems i've some problems with my new envy 15

CPU I7 720QM, which should run at 1.6 Ghz (which is not)

- Now, first my results on battery:
There seems to be no turbo boost at all. The worst part is that it idles @ 931mhz (multiplier 7) but when I run Prime (heavy app) it still runs at the same speed. So basicly there isn't any difference between idle and load cpu speed :s

I read somewhere that it don't use on battery but they have higher speeds (1.2ghz at least)


- When plugged in:
I use a 90W adapter (120W is standard), seems I haven't turbo boost here too. Clocks seems a bit higher (1.46ghz max) but that's it. I have never reached any higher numbers.

This is really a VERY BIG issue, because every app that use less then 4 threads is quite slow. (Gaming is impossable if it's not a multithreaded game)

I hope someone has a solution???

 

For the battery limitation it's a known throttling issue that exists only on the envy 15, and there was no fix whatsoever if I remember, correct me if I'm wrong.

 

The CPU throttling applies to AC power as well, but ONLY when using an adapter that is <120 W. If you use your 120W adapter, the CPU should run at its maximum speed and turbo boost should work (unless it's manually disabled).

 

The throttling issue is a safety precaution due to the chemical make-up of the battery. It's either that or risk having your battery blow up.

 

Yea, change the adaptater for your when plugged in issue.
