It could be a couple of things. The first is that screen brightness automatically dims when you go on battery, which is to save power. The second is that the brightness setting got changed inadvertently.
There are two function keys at the top of your keyboard that control screen brightness...one turns it up, the other down (they generally have a small circle with rays coming out...one circle is empty, the other filled...sort of like a sun and a dark sun). Hold down the Fn key and press one or the other of those function keys and see if that makes a difference in your screen brightness.
If that doesn't help, you may have a faulty LCD screen.
they are right about the graphics being built in and it is a motherboard replacement. However check a few things first
Plug in an external monitor to see if the output is ok - if so the graphics chip is working and it is the monitor.
uninstall the graphics driver and let Microsoft find a replacement driver.
Make sure the ribbon cable is properly connected, you need to open the device to do this.
If none of these then it as a last report you could try a motherboard reflow solution. If it is broken anyway this can't make the situation worse but I have not tried it myself yet, just heard it works. Click here to see it in action. This still wont work if a component is fried.
What is happening to your laptop is the power line connecting a row of pixels is failing so only partial colors are showing up causing the vertical line. Usually screen replacement is the only answer to fix it. You can usually find replacement LCD on Ebay.
Your ROM BIOS is asking you where to find bootable media, and when you tell it the HDD (hard disk dive), the ROM BIOS can't find a bootable partition on it and just quits, leaving the screen blank.
So, either your HDD is no longer connected to the system bus (was the laptop dropped recently?), or someone (or something - aka virus/worm/trojan/malware/rootkit, etc.) has erased your bootable OS (operating system) from the hard drive.
Fix: boot from a "Recovery CD" and use the utilities thereon to repair your OS (or at least find what's left of it), and try to reboot. Failing that, run any/all diagnostics that your ROM BIOS has - especially memory tests and HDD diagnostics. Why? (a) bad/jarred loose memory (RAM cards) will prevent booting (b) an HDD that fails low-level diagnostics may never be salvageable and may have to be replaced - it actually may have had a head crash - which tends to happen when a ZD8000 notebook is dropped while the system is running - or a head can crash for no apparent reason.
If you can get the system to boot to SAFE mode - run sfc (system file check) as your first attempt to repair the operating system - its already in Widows, here's how to run it:
START > run > sfc
As soon as you can get beyond safe mode, update your favorite anti-virus package database and run one (or more ) deep scans, until the last scan that ran to completion found nothing.
It would be preferable to replace it, of course...but it isn't really required if you're just careful. You would need to contact HP direct in order to TRY to get the part...they generally won't sell repair parts to individuals, but only to authorized repair centers.
Hello everyone please if you have a solution for me I have a HP Pavilion zd8000 and I installed the ultimate win7 everything is ok but graphics can not find appropriate drivers for ATI Radeon X600 M24, which is in it for pre Win7 Thanks for your help
well there are many different types of speeds for ram, you can have a 1gb ram card but they all have different transfer speeds, so your problem could be that you replaced the ram with a card with a slower transfer speed than the original card had
try to switch the blue VGA cable that is connected from the laptop to the external monitor. You may also restart your laptop and set aside the external monitor to check if the laptop is still experiencing garbled display... If it still is, then it is a monitor issue and need to address to HP personnel by calling HP hotline. Otherwise your issue will be resolved by simply doing that..
