Gateway laptop vertical dotted lines across the screen

My Gateway laptop is having the following symptoms:
1) BIOS "welcom" screen: Vertical dotted/dashed lines ONLY found in the left side of the screen.
2) Before windows boots: Random characters everywhere glitching and warping characters.
3) Windows XP welcome screen: Dotted vertical lines distributed everywhere.
4) Windows Desktop: Some icons (escpecially white ones) look corrupted; Dotted vertical lines everywhere. Right click menu window leaves a "ghostly shadow" of more distinguished dotted vertical lines.
5) At times there will be a static signal flicker: Dots changes color or randomly disappears. This static happens if there is no physical movements or if it is just idling.
6) Sometimes it fixes itself but it still leaves a matrix of dots. Pressing F5 (Refresh) or resizing windows or taskbar cleans the matrix.
7) Physically smacking the laptop sometimes reproduces symptoms 5 and 6, eg. smacking it fixes the vertical lines.
8) If the laptop is displaying normaly (ie, no dotted lines), opening 3d games or application often reproduces symptoms 4-7, and either disappears at reboot or reproduces all the symptoms.

This problem has happened 3 times already. Laptop has been service by the warranty and they say they replaced the MoBo. I could conclude that this symptoms can be a defective mobo memory or a loose connection. I want to know how to locate such problem in the laptop so i could fix this myself after my warranty expires.

Re: Gateway laptop vertical dotted lines across the...

Sounds like a problem with the LCD assembly or cable. You may want to reseat the LCD cable at the LCD end. It could be a loose internal connector in the LCD assembly.

Dotted lines on laptop screen

This not good, hook a spare monitor to the video output usually on the back, if picture okay! the LCD panel on the laptop will need to be replaced. But if both show the same symptom the video graphics card is bad normally built into the motherboard.

My dell lcd screen some lines vertical problem

We might be having issues with the video card or the LCD
For us to isolate where the problem is coming from
1. Tried accessing the BIOS see if the vertical lines are present
2. If there are vertical lines on BIOS definitely the problem is LCD and we to replace it
3. So if we see vertical lines inside Windows we might have issues with Video Card itself or Video Card driver
4. Try uninstalling the video driver and install a fresh copy of video driver. Else we need to replace the video card
5. Usually laptops have integrated video. So we need to replace Motherboard

If you can see the vertical lines during POST, try to check the vertical lines in BIOS. If the vertical lines are there in BIOS, the only thing you can do is to replace your LCD screen.

White line across my laptop screen vertical

Do a hard reset to the system take the battery out and unplug the power cable, make sure to unplug the acadapter from the system so there should be no power on the system, after that you have to keep the power botton pressed on the laptop for 50 seconds and then release it. connect the battery only and turn on the laptop and go to the bios screen. if the line is present in the bios too than its a pixcel problem which cannot be repaired if under warranty get the screen replaced in case its on the windows screen then you have to reload the video driver.

Vertical lines in my laptop screen

My understanding is that you have 2 laptops with the same problem, if that is the case, you need to replace the lcd. When you have lines on lcd's, that is a sign of a bad lcd.

Vertical Dotted Lines on my Toshiba Tecra


My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue related to vertical line across the screen . I would like to provide my suggestions on the issue.
I hope that this should work for you and will resolve the issue.

Well, this issue could happen due to below causes:

1. corrupted Display Adapter drivers in PC
2. If the OS gets corrupted.
3. If there is an issue with BIOS

To isolate the issue, I recommend you to try below solutions.

1. Try to work on System Restore if you are using Windows XP or Vista. Sometimes this could resolve the issue.

2.  Then try to load the PC in to BIOS, I mean get into BIOS screen and check if there is any vertical line across the BIOS screen. if you do not see such line while in BIOS, then it confirms that this is an issue with Software related and not  a Hardware related.

3. If  found that this is an issue with Software, then load the pc in normal Mode and then try to uninstall and reinstall the Display Adapter Drivers in your PC. This should resolve the issue. If the issue still persists then go ahead with Reinstall of Operating system. This is only ultimate solution for the issue.

4. If  found issue with Hardware related, I mean if you see a vertical line in BIOS screen, try to Flash the BIOS once. It means Update the BIOS. OR load the Latest BIOS that is available for your PC model.

For your convenience, I made alot of search and found a link for BIOS update.

Link is :

Once if you open the link, please select the correct Product type as : "Portables" and then Family as " Tecra" and then select correct model number of your PC and click Ok.

This opens a new web page, try to locate the updated BIOS driver. If you find there is new updated version of BIOS, then please download and install it. This should resolve the issue.

However, if the issue still persists then it confirms that this is an issue with Hardware Malfunction of PC. Then you need to contact Manufacturer on thes issue further.

This should resolve the issue for you.

 If you need any further assistance on the issue, you can mail me at . I'll be glad to help you.
