Default Laptop display blank on battery power

Hello all this is a strange problem and I have tired to fix it but can't seem to.

We have a HP EliteBoook 8440p that was working well and one day after a driver update to the intel internal graphics card( built into the cpu i5) all went bad.

With the intel driver installed the laptop screen works while hooked up to the dock or ac power but not when disconnected from the power, the screen is blank. It lights up but nothing displays. Hooked up to the dock it can do extended desktop on the other monitor no problem and even the laptop screen works. Disconnect it and it goes blank.

The only way we have found to get the internal screen to workon battery is to uninstall the intel driver and go to the stock one. Then the screen works but we can't do any external monitors or presentations.

Has anyone ever seen this before and have a fix for it?

I've come across a lot of problems when installing intel display drivers on various laptops,the best driver to install is the one from the manufacturers website which will be the latest stable driver which has been tested on your laptop.

That is the one we used and is the one that killed it.

This is the latest intel driver for Win7 64 bit. Not sure if you want to try it though.

we are running windows xp 32 bit on it. Reverting does not work. Strange this is that moving the hard drive to another computer just like it the problem does not happen. Does updating the driver somehow update the firmware of the gpu?

I never heard of the driver updating the firmware.

This is the intel download for 32bit. 14.51.4.5407 (6.14.10.5407)

http://downloadcenter.intel.com/Deta...onal*&lang=eng

You might want to try the Update Utility and see if detects an update for the graphics.

If you take it off of the dock, and hook up another monitor, does it still behave like it did when attached to the dock? If on AC or Battery, and the screen lights up, the inverter works, but most likely the cable to the lcd has deteriorated so, that the cable is no longer good.

Also, what happens if you attempt to boot with a Ubuntu LiveCD? Is the screen still blank? If it is, and you have ruled out everything you can, it is most likely that this machine is a good candidate for repair if less than two years old. Anything more than three, you are better off just replacing, since parts are sometimes hard to come by through regular distribution chains, but sometimes you can find parts on eBay or through places like http://www.sparepartswarehouse.com/ or http://www.partstore.com/

Hey guys sorry for the late display, we have not had a lot of time to work on it. We are back to it. We tested a live version of ubuntu and everything works fine. It looks like a corrupted driver in windows. Anyone know of a program that will let me search for drivers and remove them?

This will enable you to clean the video card driver that's where I'd start,often when you update the driver files with the same version will be left in place or malfunctioning settings will be left so I would try a clean install of the video card driver first.

First turn off automatic driver install

http://www.addictivetips.com/windows...windows-vista/

Quote:
Go to Start–>Search type in gpedit.msc
Click the file to open the Local Group Policy Editor and show Windows who is in control!!
You want to go here: Computer Configuration->Administrative Templates->System->Device Installation. Click on the subfolder Device Installation on the left and on the right side you will see the possible restrictions.
Right Click on Prevent Installation of Devices not described by other policy settings and edit this option, set it on ENABLED.
Restart your computer and boot into safe mode,now uninstall your video card driver and run this program to completely remove the driver.

http://majorgeeks.com/Driver_Sweeper_d6171.html

Restart your computer and open gpedit.msc again and revert the change to allow you to install the driver.

Install the latest driver.

Hey all back with an update, we ran the driver sweeper and found NVIDIA drivers on the system even though it has nothing from nvidia. It looks like the IT guy installed nvidia drivers on a system that has none. We removed the two display drivers but the system it still doing it. There are other nvidia drivers listed. We will remove them tomorrow but I was wondering is someone has a manual procedure to remove nvidia or a tool so that we can make sure to scrub the system of all left overs?

They all do the same thing as driver sweeper,remove registry keys,files from C: drive and files in the windows folder.

Read and follow this from Nvidia if you have no luck-
