When you see this warning please also check the time, when this event was happened. Can you remember, if your machine was running on battery power at this time? If so, this is the answer. At least in my case, every time I get this event id 37 warning, I was running on battery.
Got this error on my M1530 running Windows 7 x64. I could tell the system was running hot and I could hear the fans working really hard on occasions. So, I opened it up and used a can of air to clean out all the dust. Put it back together and the error has not reappeared. Seems to me the CPU got too hot and the fans could not keep the heat under control so the BIOS down-clocked it for safety.
Several posts on support forums suggested that the first step in troubleshooting this error would be to update the motherboard firmware.
