Question about Computers & Internet

1 Answer

I have an 2008 HP laptop that boots but does not have any output to the screen.Since I'm not able to check the bios by interupting the boot cycle,I thought perhaps I could perform a hardware reset on the BIOS chip and then maybe the display output would return.I know there are a lot of problems with the "black screen" so I thought I would try the easiest fix initially.The OS is Vista.Do you think this sounds reasonable and if so would the reset entail a simple unplug then plugin type procedure?

With the HP series of laptops, I doubt that resetting the bios chip would have any effect and you would not be able to see what is happening, what you describe ( a bios flash) is not the easiest solution.

Try it on an external monitor, if the problem persists, then you have the usual failed Nvidia graphics chip problem, all too common with HP laptops as they overheat and need to be "reballed"

If you can get an external picture, issue is likely to be with the inverter, the screen, or maybe just a loose cable or in extreme circumstances, a damaged vga cable

How to change setting in bios to boot from cd drive"?"


you usually dont have to change the boot order to boot from a cd. the bios should check the cd rom before booting from the hdd. However, if that isnt the case, you can always change the boot order.

go to the bios settings while u turn your laptop on. (It should be "esc" for HP. a message will be displayed at the bottom of the screen indicating the key. if not, try esc, f10, f11, f12. either one of them should work).

go to the boot order settings (May have a different name- boot settings/ boot priority settings/ advance boot options etc.).

Hp pavilion dv9000 takes a long time to get past the bios screen. It won't boot of dvd either??


Check BIOS boot options and assign local hard drive as first for faster boot. This is also where you set CD\DVD as first to boot from disc. Look for F Key press on start up. It will be shown on screen. These can vary.

Many HP machines also have a boot menu option during boot. Again an F key and may vary.

How do I fix or repair my HP mini 1000 Netbook with it being stuck in a boot loop? I am getting the "unmountable_boot_volume screen. My netbook does not have a CD ROM drive.


Check your bios to ensure its first boot option is set to the hard drive instead of CD drive or USB drive. If you have a thumb drive plugged in, unplug the USB and try again. On your boot screen there should be an option to hit a key to enter bios (Usually Esc, F2 or Del). Hit whichever key it requests and enter Bios. Once in Bios look for Boot Order and check to see where the Hard Drive is in the order. If it is not set to #1 then do as it says to set it to the first option. Once done hit F10 to save and Exit and return to boot.

Dv6000 will not startup ,Black screen , hd isnit being accessed


When you first turn the laptop on is there a HP splash screen? Can you enter the BIOS (normally by tapping F2 or Del key). If so then it would seem the BIOS updated OK. If when you turn it on there is nothing the BIOS flash probably went wrong and the machine will need a new BIOS flash chip installed.
If you can access BIOS then it may be a simple problem that the new BIOS reverted to default values. The most common issue would be the boot mode of the HDD. Look through the BIOS menus and there should be an option for boot which will say AHCI/IDE/Compatibility. Try changing it to another option, save and exit BIOS and see if that helps. Try this for each option.
Alternatively tap F8 continuously when you turn the laptop on and see if the advanced boot menu appears, if it does try selecting Safe mode with networking.
Finally to test if the HDD is actually working, try downloading Hiren's BootCD and boot to it. Then run some HDD diagnostics to see if the HDD is operating correctly.
Hope this helps,

Opened my lap top HP dv9000 black screen sounded like it was running, I shut down then tried to reboot,starts to reboot then cuts off then tries to reboot and continues this cycle


Try starting the laptop in safe mode.
This is done by pressing F8 while the computer is starting. You will be presented with an option screen and should in the first instance choose safe mode. If the laptop boots you can then check the hardware for faults. If you are not getting past the initial bios boot screen it would be worthwhile downloading the latest bios firmware from the HP web site and installing this.
