Thanks a lot!
I am not going to edit BIOS then, but will update to F.59 cause “Improves the performance of the SD card reader” as said in HP site.

I have read in another forum that reducing the “max power state” in “processor power management” to 70% may help. so i will stick to that and try.

Yours

Thank you Naser for reporting the new BIOS!
As far as I know there is no easy way to manually control the fan speed whatsoever.
Between versions F.45 and F.51 there has been a change in the internal fan policy as I described above, however not even upgrading to latest F.59 would enable you to tweak its speed.
To be honest there actually is a way to tweak the fan speed, but involves editing the BIOS image and is tremendously unsafe…

Thanks for the great page!
I am using a HP dv6799ea, with F.58 A BIOS already. Have been trying to find a way to control my fan speed via different programs such as speedfan lately but wasn’t able to do so. I want to know if it is possible to do that any way with changing BIOS to even older versions; or trying to it manually via direct access to ACPI which is a little risky as I
Will updating to latest F.59 BIOS release help or not?
BTW, here is the links for F.59:

Thanks for your consideration in advance.

Paul & Aldeby

Thanks !!
You were right.
The thing is I have never tried to get into bios setup with USB drive inserted. If it is not you cannot see any options related to USB (in my BIOS).
My only justification is that firsty I wanted to know if sth is possible…now I can see how wrong I was

Taras, as Paul kindly pointed out I’m 100% sure you actually can boot from a USB pen drive or even USB external hard drive.
There actually is an option in the BIOS but it does not say “boot from USB”. You can find it under the Boot Sequence menu. By default you should have DVD -> Hard Disk -> other external devices -> network. You could set it to first look at external devices.

I actually would suggest you to rather follow Paul’s advice: keep pressed F9 key during bootup (I mean since the computer leds get switched on!) with the USB disk inserted. It then should prompt you with a menu in which external USB disk is an option.

For the USB disk to be bootable you have to first make it bootable, of course. This can be accomplished with several tools: the most popular being Ubuntu’s usb-creator and unetbootin (available for both linux and windows).

As a reference check this thread: http://ubuntuforums.org/showthread.php?t=811397

once (year ago) I talked to HP support but they answered me that USB drive is not recognized by HP as ‘bootable drive’ (?)
Probably it meant that it is not implemented in my bios.
so I resigned from idea. Now I’ve found this forum and list of updates for my bios. Seems that nothing has changed.

I see, sorry for the confusion. Even in the boot options under system configuration? That’s weird, most newer models have them already. In that case you might be in a stump hehe. Any luck talking to an HP rep about it?

thx for reply.
to be clear.
In my BIOS there is no such option as ‘boot from usb’

@Taras
I’ve booted from a USB drive running Ubuntu, you just need to set up the boot order of your laptop.

I have an HP DV2725TX and just press F9 when the BIOS screen opens. By default, the BIOS screen “timeout” is 0 seconds so you might not be able to see the instructions. You can just keep on hitting F9 as soon as you turn on your PC.
