We are novices on computers. My son was gifted a ThinkPad Carbon Gen 8 and it needed a new battery so we ordered on and he replaced it. Since then the coloring is off and there are vertical lines on the screen. Can anyone give a recommendation on why and what we can do to fix it?
Esta é uma boa pergunta?

Hi @jennifers67012 ,
Can't see any obvious physical damage to the screen in the images you posted so try connecting the laptop to a TV using the laptop's HDMI connection and check what the images are like when viewed on the TV.
If the TV display is OK then there's a problem with the screen.
It could be either a loose LVDS (video) cable connection (at either end, motherboard or LCD panel) or a faulty panel.
If the TV display is also not good, then there's a motherboard problem and further testing using the schematics would be required.
Is the laptop's display OK when either entering BIOS on startup or starting the laptop in Windows safe mode?

Thank you! The screen is the same in safe mode. We have a friend in IT who is going to take a look at it for us.
Safe mode was only to check that the problem was due to a software problem i.e. if it was OK in safe mode it most likely would be a software problem and not a hardware problem
As it is still happening in safe mode it will be a hardware problem.
Is the external monitor display test OK, you never said?
