I'm having the same exact issue with my pavilion ze4500 with windows XP (Computer powers on, loads HP black startup screen (where it says to press ESC to change boot order, F2 for setup, etc.) then changes to a black screen where this text appears “Initializing MBA press ctrl +alt+B” after that it goes to another black screen with the “PXE-XXX media test failure, check cable” error (among other text, something about “Argon Pre-boot Bios….”) and after striking a key it comes to a black screen with only the words “Operating system Not Found” on it, with no options.
These are the events leading up to the above; It all started when I tried to upgrade to Windows 7. I needed to do a fresh install (had some weird malware preventing me from being able to set a wallpaper) so I deleted both existing partitions and created the new before proceeding with the install. After the install, windows 7 had a terrible time loading (all the graphics were distorted and system moved very slow, couldn’t see the task bar or hardly anything for that matter, as if all drivers were missing or something) and after it finally appeared to be loaded, none of my hardware was recognized when I checked system info. At that point I couldn’t think of anything else to do so I took my XP startup CD and did a clean install of that (deleted existing partitions and created one new one) XP had to reformat my HD in order to do this, so I let it. I got all the way done with the XP setup and windows booted normally, but for whatever reason the accounts I “set up” (all I did was put a name in the field for the account name) were asking for a password, which I never set up. So I was stuck once again, this time at the log in screen with no ability to log in. I decided that maybe I missed something during set up and inadvertently set up a password, so I tried doing yet another clean install, however this time when I rebooted to do the install, the above started happening, the computer booted to the HP startup screen, but never asked to boot from CD, just went right to this Initializing MBA screen and so on. No matter what settings I choose in my bios setup, this is the result. It appears that bios recognizes my hard drive, so I’m thinking that it should be just fine, but I’ve read a lot of comments about the HD being bad as a possible cause to this error. (Among many other possibilities!)
This is what I’ve tried doing so far;
Reset bios setup options to default,
Tried various ways of using the “reset” button on the bottom of the laptop to reset the bios,
Changing boot order through setup/esc key, no matter what the order is it still goes to the error screen, (I can’t figure out how to “remove” one of the options from the boot order, I read some suggestions that stated to remove the boot to lan option from this, not sure how to.
Off of the HP website (Specifically the ze4500 model troubleshooting section) it said when receiving the “operating system not found” error you need to test the HD, to do this it says to hold F10 while powering on the PC, then to let go once text appears, this did absolutely nothing whatsoever! To get to the bios setup you have to use F2, not F10, so I don’t know what they are trying to pull there. When I press F10 at start up it does say “Starting diagnostic” but then ends up going to the same damn error screen above after a short pause.
Physically removing hard drive & battery to check connections, pins are fine, connections seem fine (didn’t take anything else apart)
Booting from the OS startup disk and the “recovery” disks provided to me from the manufacturer, for some reason the drive lights up and spins, but the system never asks me to boot from CD, nor does it boot from CD on its own.
It sounds from this post that my CMOS battery may need replaced? After looking at the procedure, it’s not something I really want to just “try” doing without being sure it will correct the problem. So anyone have any advice for me?
