For Online Computer Support, Ask a Computer Technician
Hi Alan and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model number of the ThinkPad; perhaps a T430u rather than T4300?
And would a LINK to an online seller for a replacement LCD screen serve your need please?
On "...How can I get a replacement screen for a think Pad?..."
