My Dell's ac-adaptor sort of died on me. The laptop now gives warnings every time I boot it and:
*Warnings: "The power adaptor you are using cannot be recognized. Please use only authentic Dell adaptors with Dell laptops. Your battery will not charge and the computer will operate at the lowest possible speed. Contact Dell support for more detail.
The Battery won't charge anymore.
The CPU speed is locked at 800 MiHz with a 6.x multiplier... Instead of 1.73 GHz
Now, I don't use the battery that much (it's a 17" laptop) but I can't live with the CPU's new 800 speed...
I found some advice for overriding this on Ubunutu (a kernel trick I can't find the link for) and Win XP (prog: Switch XP); but I need something for win7. Maybe a software over-clocker or real-time freq. controller...
What do you think?
Found a fix. Manual, annoying, temporary... but it works!
