    Can a 19v power adapter be used in a 20v computer?

    Thanks makkem The original power adapter which came with my laptop was 90W, 2.25A, 20V. Lenovo replaced it with the same 90W, 2.25A, 20V power adapter. I'm now considering another power adapter that is 90W, 4.6A, 19V. I'm trying to make sure that it is safe to use. Louis has some concerns.

    Can a 19v power adapter be used in a 20v computer?

    My Lenovo Thinkpad Helix 36984SU comes with an output 90W, 2.25A, 20V Power Adapter. I can connect a spare Power Adapter with an output that is 90W, 4.6A, 19V. Is it safe to use or can it damage the unit? Will it effect any of the functioning of the computer?
