    My Travelmate (info in my sig below - a TMP-645MG Windows 7/64 Prof system) has been throwing Event ID 37 errors, saying something like this for processors 1-4:

    The speed of processor 1 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.
    ​
    I've been all over Google trying to find answers but I think I've hit on it, and it seems to be pointing to Acer's 2.13 BIOS update that was released in February. I notice that the error timestamp is always at boot, even if I do not log into Windows for several minutes, so I started to suspect the BIOS. When I looked back into the history of these errors, they started immediately after I upgraded to 2.13 (the date I downloaded that BIOS was precisely the same date as the first Error 37 in my event viewer).

    I am about to upgrade to BIOS 2.14 - and if that fails to resolve, I may downgrade back to 2.09, which is what I had before. But I was wondering if others here are seeing similar errors in their event viewers.

    Same problem with 2.14 - four Event ID 37 errors at boot-up. And now I find that the BIOS utility balks at downgrades. So it's either fix 2.14 or find an avenue for the downgrade. I would prefer the latter....

    And now I'm getting a ton of network errors - 1014 and 1001. Resetting the connection yields page loads that take about four minutes, so too slow for much use. I'm about to give up and tear everything down and rebuild via the partition disk. Will that bring me back to the original BIOS?

    So I tore down everything and restored the system to factory settings. The BIOS did not roll back - remaining at 2.14. I rebuilt the system, which pretty much has taken a day and a half to do so far. Unfortunately, the Error 37 still occurs, and I get network drop-outs or slow-downs without any effect on the desktop - which is also tied to the modem. SO I'm really scratching my head on this - reluctant to try to roll back to the previous BIOS, but I think that the newer versions are turkeys.
