Hello: I have this weird problem where my thinkpad t61 screen, for no apparent reason, slowly dims almost to complete darkness, then immediately brightens up as if nothing happened. The entire process can take between 10 to 30 seconds, and I have not seen any pattern or reason why this might occur. Any suggestions to eliminate this problem would be appreciated.

The issue could be with the inverter board.
Kindly update the latest BIOS and update video driver and power manager software, check if it resolve the issue else get it check with Lenovo authorized service center
