IMPORTANT !!!
Obtained the correct BIOS file, HP seem to provide many different BIOS's.
For instance the BIOS for CQ45-107AU is not the same as CQ45-107TX.

For the CQ45-107TX I used the Insyde BIOS version F.04 file 30F7F04.FD then

  • Renamed the file 30F7F04.FD to 30F7.BIN and placed it on a USB thumb drive.

    Disconnected the AC adapter from the notebook.

    Removed the battery from the notebook.

    Inserted the USB thumb drive into one of the USB ports on the notebook.
    Didn't seem to matter which one.

    Held down the 'Windows' Key and the 'B' key.

    Connected the AC adapter.

    Pressed the 'Power' button on the notebook.

    When the LEDs came on, let go of power button and the two keys held down earlier.
    On the CQ45-107TX the touch pad LED came on as amber (disabled) instead of the normal white (enabled).

    After about 10 seconds the notebook started reading the USB thumb drive.
    While searching for the file the notebook beeped once a second.
    The number of beeps varied, depending on how big the thumb drive was and
    the number of files on the thumb drive, from just one beep to many.
    If the file was not found, the notebook would reset itself and try again.

    If the file was found then it took about 12 seconds for the notebook to load it.
    No beeping sounds heard during the loading time.

    When loaded the notebook started flashing, indicated by beeps every 2 seconds.
    This took about 32 seconds.

    About 5 seconds after the beeping had stopped the notebook shutdown.
    BIOS worked normally thereafter.
***Note: i'm doing this for the Envy 15-1050nr

What do you mean by cooling fan problem? Is it overheating & shutting down? Is the fan running all the time due to the heat? Be more specific & I will try to give you appropriate advice.

    Never heard of a system not starting because of a fan problem. Fan really does not become an issue until overheating occurs. Are you able to access the bios? How were you able to apply the bios update if you are not able to start? Or, does your hardware start to load Windows, but never complete the boot cycle?

Sounds like the fan might have dust build up on it. If that is the case the best thing to do is get a new fan. You will have to take the computer apart and check the fan to see if the dust has built up. If not then the barrings maybe shot. In which case you will need a new fan.

Hope this helps.

HP dv6 overheats, fan runs but little air comes out. Warranty just ran out, of course. On start up sometimes error message is "operating system can not be found"


Overheating is undoubtedly caused by obstruction to air flow in between the fan and the vent. The heat absorbed by the heatsink is driven out by the fan and when some obstruction(usually lumps of dust comes in between, this overheating problem appears. You will have to open it up and clean the path of the airflow to resolve this problem. As for the OS not found option, it is most likely to be due to a HDD crash. See if BIOS detects it. If it does it is not a malfunction and is definitely a crash. I am afraid you will have to re-install windows to resolve this problem.

I have a Hp Pavillion a6650F. Recently the top fan in the back sometimes whirres. Is there anyway I can adjust it or lube it> Or what should I do to fix this?


There are multiple things that can cause this, I'll briefly describe them and solutions.
  • It could be having issues spinning, causing a forced spinning whirring sound. This is most often caused by dust and can be fixed by buying some compressed air computer duster.
  • It could be overheating, many laptops have this issue. When a computer heats up, the BIOS tells the computer to increase fan power, causing a more noticeable fan whirr. This can be changed in BIOS settings, but I do not suggest it, or you can buy an under the laptop fan to help cool down the laptop.
  • It could be breaking, in which case buy an under the laptop fan to prolong your laptops life, however if this is the case your laptop may only have a year or two left and I suggest you start making regular backups of important files.
