Bad Component in System A possible reason the ThinkPad will not turn on is a bad component. Do this only if the previous two steps did not yield results. Remove these components of the ThinkPad after disconnecting the AC adapter: - Battery Pack - Memory Module (DIMM) / RAM sticks - Any replaceable cards externally inserted - CD-ROM, CD-RW, or DVD drive if it’s replaceable - Hard drive Wait 30 seconds, then reinstall only the memory DIMM and functioning battery pack (or plug the power cord in). Reinstall devices one at a time in the reverse order.When reinstalling the hard drive, disconnect power and battery pack first, then plug back in after reinstallation.
This process will help you identify which component is malfunctioning. Backlight If the back light isn't working several parts may be bad. The inverter, the inverter cables, the display, or the logic board. If the backlight works intermittently and fails when the display is moved around, the problem is with the inverter cables. If its not the inverter cables it is necessary to replace parts one by one to seek out the damaged part.
First, replace the display inverter. If that doesn't work, replace the assembly. If that doesn't solve.If that still doesn't solve the problem, a new logic board is needed.
