I recently noticed that when I use my laptop on battery power, I get 4 instances of "Kernel-Processor-Power" in Event Viewer every time I turn on my laptop (ID 37 (7): The speed of processor 0 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report). This never happened before. When I'm at home, I usually take the battery out and run the laptop on AC power, in which case I do not get these errors. This makes me think that my battery may be faulty.

Additional notes: My ASUS laptop is only 4 months old running Windows 7 and Intel processor. I Googled this error and I have made sure that my BIOS is up-to-date, that the power settings are consistent, and that my battery and laptop connection is dust-free. It was also suggested that I look into BIOS settings and although I don't remember exactly what I was looking for, I know that I did not have such settings (I think it was Intel EIST). I don't know when exactly I started getting these errors, but I know for a fact that they did not exist awhile back. Is this anything I should be worried about? Thanks.

You should discuss this issue with Asus if the computer is under warranty. From the info in link below you have
a 2 year or 3 year warranty depending on model.

Thanks for your response, but I managed to fix it. When I was adjusting the power settings, I only changed the "maximum and minimum processor states" to be the same for both AC and battery. This was done through Windows 7 built-in power management. However, I use Power4Gear (power management software for ASUS) and I overlooked "processor control", which was set to moderate battery saving.
