WONT BOOT UP

a1340n,windows what?
this pc Desktop is now retired at HP, no support. 12 years old now.
that depend on 2 things what is wrong.? (hdd or OS dead)
came new with XP the dead OS>.

if you have the HP hot key f11 working
or of you have the HP install media kit for it.

i guess the screens ok, and BIOS is OK, hit the bios key yet? power on hit what the screen tell you, at power on.
if that works and the OS fails to boot?
that means the startup files are bad on hdd
or HDD is bad
or the OS is corrupted.

what I do is boot to linux live cd/dvd or usb stick
if that works we know the HDD is the problem in 1min flat.
the we, hit f11 at power on and pick restore, and pick

the 2005 is us on the cusp of having F11 working or not
F11 is the key that has the full XP install on the HDD.
we run a linux (knoppix 7) DVD there and do the DISK test there.
if that fails the HDD is bad.
see it run here, this live DVD OS is the best test disk around.
and 100% free. if you can burn it or burn to USBSTICK mem.

running knoppix tells me pc is ok
and at same time the HDD is good or bad.

if the F11 key works, then if lucky you can do repair restore.
or a start up file fix.
F11 runs the HP restore partitions,
id read you service Guide for you and look but HP deleted it.

U use your keyboard during the boot process to get into the Cmos menu. Varies by company - could be the delete key that you have to hit, F2, F11 - like I said it varies and you will have to experiment unless you can get the info from the mo bo site.

While your system is still booting from start, keep hitting F11 to get past that point then proceed with the system recovery.

You could have deleted the keyboard in the device manager. If so, rebooting your computer and it will find it.
Are all the keys not working or just some? Take a look at this hint and see if it fits.

I do this for fun & feedback not $$$

During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
or
During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer
hope this helps

do you have a recovery cd or a copy of windows xp, try pressing f12 to get to a boot menu or f8, to get to a safe boot option or a last previes known good option, or some thing like this. press these options on off on off just before it goes to load the windows. try that hope it helps

Open a notepad using mouse and then check if u can type in notepad.
Shut down and reboot the system and boot in bios by hitting F2 or F10 or Delete key on keyboard. If u are able to boot in bios ,reset bios.If unable then disconnect keyboard and try different port to connect.If issue persist replaced keyboard.

¿Did you try hitting ESC at boot time? If it doesn't work try turning off the unit, remove the battery for 10 seconds, put the battery in its place again and boot again.

This feature is turned on and off in the system BIOS.

During startup, hit either the DEL or the F2 key to enter the setup.

Read through the items found there until you find the keyboard options.

good luck.

ok fair enough.... boot the computer and watch the screen.... you need to watch for the key to enter setup.... delete key seems to be the most popular but i've had computers use f1 and f2, f11 and f12.... if it goes to fast hit pause as it gets to the point where it tells you the key to hit to enter setup.... after you are in change the boot sequence to boot to cdrom..... hit f10 and save the changes... reboot to the cd and continue with your install
