My friends netbook has been acting up since Wednesday night. He booted it up and the whole screen was malfunctioning before there was nothing on the screen and no backlighting. By malfunctioning he means a portion of the screen is copied and fills up the whole screen. I'm guessing its the LCD screen but I'm not really sure. I have already reseated the ram and hard drive. Take it apart and replug in the screen cable but still no luck. Tried 2 different hard drives and that still didn't work. Also i tried to connect it to a external monitor but no image. Any solutions?

Update: I got the screen to show a image 3 times but they all went weird.

To me that has to be faulty video RAM. Does that model have dedicated video memory, or does it use system RAM? Harder to test dedicated memory - if the video is grabbing some system RAM, and there is more than one DIMM, try swapping DIMM slots. If the RAM is faulty, you should then find the video works normally, but Windows will probably crash as it will get the faulty memory locations.

The indication that it's RAM is on the low resolution startup screen, there are only a few aberrations, and they are wide (5 across the screen). In the higher resolution graphic mode, they are much narrower (10 or more across the screen), this appears to be the row and column addresses of the RAM which occupy more of the screen at low resolutions, and proportionally less at higher resolutions. Seems those memory locations have stuck values, so just display bars instead of accepting the image data.

For some reason with a few bangs on the screen and it works now. But since this is a netbook, i can't install windows. I have made a USB windows installation but everytime i press F12 to change the boot order it doesn't let me into it but when the USB is not plugged in, it let's me into the boot order.

That seems a bit odd. I wonder if there's a security setting somewhere in the BIOS that can be set to prevent booting from USB?

My friend forgot the BIOS password, so i can't access the BIOS. The only option left for me to use is F12 boot menu. I am currently creating the USB windows again on a different USB.

There is a way to clear the BIOS password, I most likely can not post the procedure here, but I can however PM you a link to another web site that explains how to do this.


As for the problem with this laptop, it is sounded to me like a possible intermittent connection, caused by a loose electrical connection or possible oxidation corrosion.

This can be cleared up by physically opening the laptop and carefully checking all ZIF connections.
ZIF connectors are those ones that have flat ribbon wires going to them, they have a plastic flip lever that locks the ribbon wires into the connectors.

You have to be extremely careful not to break off those flip levers or you'll brick the motherboard, those are impossible to replace once they are broken off.

So please be very careful when trying to check for faulty or loose connections!

Bruce.

I have already taken it apart and reseated ZIF connections which leads to the screen. As for the BIOS password, that link is only for desktop but it did link me to a laptop one but every less info. I have found generic password for BIOS which i will try after windows update.

I decided it was best to remove that link because it most likely goes against the forum rules and following the rules are one of the most important part of being with the Bleepingcomputer staff. :thumbup2:

If you are having issues with both the laptop monitor and an external monitor it means there is an issue on the motherboard, if it is not a loose connection, then it is most likely a failing video processor chip, some laptops had faulty Nvidia chips built into them, they were recalled, so I am not sure if this laptop brand was included or not, might want to look into that possibility.

It's a Intel video processor chip not a Nvidia. What's interesting is when the screen is just blank the hard drive light flashes for a second but when there is a image on the screen the hard drive light flashes normally. I have already reseated the hard drive.

What you really need to do for the most part is find a legal way of clearing that BIOS password and gain access to the laptops BIOS settings.

If there is a setting that has been previously set that does not do a default reset during such an error, it can prevent normal operation of the laptop.

Because laptops are portable and often used for Government and business, employees often leave them in automobiles and are stolen by thieves. Because of this, they often contain passwords to help protect the data on the system hard drive.
The only legal way of clearing that password would be through contact with the laptop manufacturer, in this case it is Lenovo, prove that you legally own the laptop and they should be able to supply information on how to clear or reset that password.

I do not believe the only answer is to replace the motherboard, there is a way, it is just a matter of proving you own the laptop and it clears any possible theft possibilities.

Has anyone contacted Lenovo for product support?

Bruce.

Maybe there is a CMOS battery somewhere under there but i it's working fine now at the moment and hopefully it doesn't go blank again. My friend has already picked it up 2 days ago, he has hasn't said anything to me yet about it.
