My laptop are having an issue which is there are green and pink colours vertical lines on my laptop screen. When i pressed on the screen, the lines WONT be affected.
I've tried some ways from online to figure it out what's the problem, i've tried enter to BIOS mode, and the lines still there. Did that means it was Hardware issue instead of LCD ? How to fix it?

Hello Tzion. Welcome to TSG!!

It looks like the LCD itself is going south. There's really no easy, economical way to repair t he screen. You'd need to replace it. It's up to you to decide if it is worth it to you to do so. If you are somewhat technically and mechanically competent, you can most likely repair it yourself.

YouTube will have videos to demonstrate the disassembly of either your model, or one similar enough to show you how to replace it. You can search for a replacement screen for a price estimate. I'd wait until you can read the numbers on the back of the LCD before ordering a replacement.

To echo what has been mentioned, the most likely cause is a defective LCD screen.

Hardware Maintenance Manual - ThinkPad T450 - Here is the manual. It looks like the LCD comes in a unit and the procedure does not look too difficult to replace.

FRU is 04X5914. You are looking anywhere from $75.00 to $100 USD depending on where you go. You will need to look for that FRU in your country.

You can look up the parts of the computer by going to the Lenovo Service Parts Lookup page. By providing the serial of your machine (in your case: PC0AGC2Q), you can find all the part numbers. Whether you go to Lenovo or a 3rd party, that is your call. Going to the manufacturer would be preferable as you know you are going to get the correct and quality part, but generally more expensive.
