Different suppliers may qualify as power supply vendors. Always match replacement fuses to
original fuses.
Warning:
For protection against fire replace the fuse only with the same type
and rating of fuse.
Some power supplies have axial fuse holders. Place a
screwdriver on the metal portion of the fuse, and
gently lift the fuse from the socket.
Some power supplies have fuse holders with round
caps. These fuse holders are sealed with a silicon
RTV type adhesive. Break the silicon seal. Use a flat
bladed screwdriver to gently open the top of the fuse
holder, then remove the fuse. Apply a suitable
adhesive to the fuse holder cap upon re-assembly to
preserve the computer’s shock and vibration
specifications.
