What do I do when there are vertical lines on my laptop screen?

Why am i getting lines on my laptop screen? and how to fix it?

• i have a Compaq one. the lines look like static you get on a t.v. screen. they just appear then disappear. it started happening when i would close and open my laptop without shutting down or logging off. the first few times i did this nothing was wrong though. but recently it's causing problems. now i stopped doing that & started shutting down first, but today when i turned the laptop on the lines came back. it happens at random what can i do to fix this? i'm only 15 btw so i don't know much about how it works... is there a non-expensive way to fix this? what happens if i do nothing?

• Answer:

  First of all, try connect your laptop VGA port to an external LCD monitor screen to see if your Compaq laptop backlight is defective. Boot in "safe mode". As it starts up keep tapping F8. Highlight "safe mode" and press enter. See if your Compaq laptop works normal. If it runs normal now, do the following maintenance and tune up: Scan with a antivirus program & spyware/malware program to see if there is any unwanted programs. Remove the unnecessary programs and applications. DEFRAG C: & CHKDSK C: ; use external harddrive for all future downloads. Clean up registry problems using Reginout registry manager. If problem persists, as a last resort you might need to fdisk, reformat your Compaq laptop hard disk clean and reinstall OS. But before doing so, try the steps above first. Also, try remove the battery and charger/ac adapter/power cord from your Compaq laptop, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. This clears your RAM and is like a hardware reset. Replace the battery and charger/ac adapter/power cord and turn your laptop on. Check if it's something to do with your laptop power cord or power source problem. Insufficient power might cause some of those issues as well. Take the battery out and power on your Compaq laptop with the charger only. ---Make sure your laptop power jack and charger plug tip are securely connected. If power jack is loose you can find laptop power jack on ebay. However, fixing and soldering the power jack requires professional skill. --Always, the green/blue LED on charger needs to be constantly on. If not, replace the defective charger. Since battery/ ac adapter has its own lifespan and does not last forever, to help you save up some, you can consider getting a Compaq charger under lifetime warranty from store like topmic.com Wish the Best.
