FIXING A LENOVO THINKPAD T450S WITH NO DISPLAY

Fixing a Lenovo ThinkPad with No Display – Step-by-Step Logic Board Repair Problem Diagnosis The laptop powers up—fans spin, LEDs flash—but there's no display output at all. After ruling out common culprits like RAM issues and display cable problems, we zero in on the logic board, where a blown fuse is silently sabotaging video functionality. 🛠️ Tools Used To carry out this repair, we used the following essentials: Screwdriver: To safely open the chassis and access the internal logic board Multimeter: To locate and test the faulty fuse suspected of causing the problem Heat Gun: For precisely removing the damaged fuse without harming nearby components Soldering Iron: Used to bridge the faulty fuse with a wire replacement, restoring the electrical path Isopropyl Alcohol: For cleaning up the work area after soldering, removing flux residue and keeping the board pristine ⚡The Repair Process After carefully disassembling the Lenovo ThinkPad, we identify the blown fuse using the multimeter. Then, using a heat gun, we delicately remove the damaged component. A thin wire is soldered across the pads to bypass the fuse, restoring connectivity. To finish up, we clean the board with isopropyl alcohol to ensure there's no leftover flux or debris.
