Problem: Laptop (HP Pavillion DV2700) has an intermittent fan. Fan goes on for a second and then stops, goes on again, stops. While this may be OK for the hardware (but who knows) it drives the user nuts.
Cause: Laptop bios upgraded to F.2E (latest)
My Fix: Downloaded and installed F.25 (older version) and this stopped the intermittent fan. I hope that this does not lead to overheating problems, I should monitor CPU temps.

I can confirm this issue. I just updated the BIOS today to F.2E and immediately got the fan problem you mentioned. HP did a 'Fix' in BIOS version F.2B that allowed the fan to function at low speed when starting the laptop. This fix doesn't seem to work properly on the dv2742 laptop.
ReplyDeleteMy original BIOS was F.26, but I noticed that on HP only F.25 is available for download. So now I'm obliged to go back to a BIOS one version before the one that originally came with my laptop. Unless there is some way to use the BIOS flash software to restore my previous BIOS?
