I am working on a laptop problem, its an HP Pavillion DV5000 (DV5244eu)
First Problem: When switching on all of the blue LEDs illuminate (apart from mute button) but the screen was black, I have sussed out that although the screen was black the laptop was in fact on its just the the LCD back light was not working.
After trawling for a fix I found a fix ref pressing the power button for 60 secs with no battery or AC power, this did not work. Some more investigation revealed that this could be the screen inverter? but after reading further it could also be the magnetic lid closed switch.
The easiest of these to investigate was the magnetic switch so I took the top cover off to expose the lid close magnetic switch and blew around, replaced the battery but no AC power and switched on the laptop and low and behold the screen worked.
However now when connecting the AC power the screen does not work again!!!
When connected to a monitor to check that the laptop worked it gets passed the windows loading screen but stops at a BSOD (STOP ERROR 0x0000007E)
It will not boot into any other options, so it looks like a repair install or re-install of Windows XP Home.
I would in the first instance like to use HP's built in recovery and found this link:
Performing an HP System Recovery in Windows XP HP Pavilion 542x Desktop PC (US/CAN) - HP Customer Care (United States - English)
But hitting F10 after the HP Advent splash screen does not give any recovery options only the standard Safe Mode, Last Known Good Config etc. It makes no mention of recovery CDs being required but the user has none anyway!!
Will F10 only work when booting from CD?
F8 - Advanced boot options (Disable Auto Re-Start and Enable VGA Mode plus a couple of others, but no recovery mode.
F10 - Standard boot options
F11 - Standard boot options
Apart from using another copy of Windows Home and doing a Repair Install or Fresh Install any ideas??
I do have a 2.5 IDE to USB adaptor so I could access the HDD and try to recover the users documents before re-installing the OS.
