Envy 14 i7-720QM CPU Performance Issues? Advice appreciated

Hi Guys!
Over the past couple of days i've been trying to get a feel for my new Envy 14 preconfigured with an i7-720QM. The computer benchmarks fantastically but the experience isn't really what I hoped for.
While idling, the processor is @~60°C and the fan noise never really steps up or down. This isn't really an issue for me, BUT whenever I begin cranking up my performance requirements (gaming and during stress tests), the i7 automatically clocks itself down to ~500Mhz when temperatures reach ~75°C instead of kicking the fan up a notch. This introduces major drops in performance and games choke from what was previously 40fps to a measly 4fps.
The lagging happens until the temperatures return to the low 70s (which means this whole process cycles every couple of minutes as the CPU heats up again!)
Before posting a new thread on this, I tried a couple of things. Running on the Power Saver profile limits the processor to ~1Ghz, which prevents heat up and delivers just enough processing power to get by on most games.
Let my tell you guys that the link between performance and temperature seems credible (as all the data from speedfan and cpu-z indicate) but it doesn't mean that it's the source of my problem, merely a side effect. Another theory of mine is that the power supply isn't providing enough juice. Whenever plugged in the following message pops up:

I've got the stock 90W adapter. Is anyone else facing this issue?

I know I've found a workaround but this sort of thing isn't really acceptable, should I contact HP? Getting a replacement would be MEGA hard since I imported it from Germany to where I live now, Bangladesh.

Or is there a way to fix it? Is it my CPU? my fan? my power adapter? me?
I would be grateful if someone could point me in the right direction.
Thanks,

see if you can:

reapply TIM
disable HyperThreading. <-- saves a bit of power, and create less heat if done

 

I have BIOS version F.23 (dated 15 Dec 2010) but I don't seem to be able to find a way to toggle Hyperthreading through it. Is there an alternative method?

By TIM, i'm assuming you're talking about the thermal compound? I'll go ahead and try it but i'm new to tinkering with hardware...not really comfortable with it. Will it void my warranty?
I guess it's time to study those teardown youtube vids!

 

Well, my experience with recent HP laptops is they don't have those wierd warranty stickers preventing you from openinn up your laptop. Check the manuals section of your HP Support page for your laptop. It *should* have a guide on how to open it up.


Though, in my experience, that guide has none of the screws correctly listed.

 

I am getting the exact same message about the AC adapter since day one (computer is in my sig), still haven't found a solution, but don't have any of the throttling problems you've described. Mine works very nicely with lots of stuff open, with many games (well, what I've had time to try in a week), etc. It only won't go to 2.8GHz when I stress only one core. I've been testing with Prime95 and CPU-Z up and it maxxes out at 1.75 GHz with all cores / all threads stressed (this is more or less normal), and about 2.4GHz with just one core stressed (it should go to 2.8GHz). I'm ready to live without those 400MHz since nowadays almost any piece of software has proper multi-core support, but I'd also like to find a solution. BTW I've also tried a universal 90w Kensington brick and the problem remains (so that's not it).

 

I had the i7-720 for about a week and I had no stuttering / throttling issue.
I had the stock 90W adapter as well but had no issues really. You may have a faulty build, if you are still within the 21 days, i would consider returning it.


(I finally returned it when the radiance came back, now waiting for i5, as the i7's battery was too short and didnt need the +20% power)).
