If it has fan power than all is well. The newer models can handle a zip verywell. What cannot handle it is RAM.
Most new power supplies have their own switch and it often times has a power off..

Power surges, such as those caused during lightning storms, can often cause power supplies in electronics to fail. Sometimes, if you're lucky, the manufacturer will have placed a protection fuse in the power supply which can be replaced after a surge. If there is no such fuse, the power supply typically will need to be replaced for the equipment to regain function.

It is VERY IMPORTANT to use SURGE PROTECTORS on all electronics, especially if you live in an area where thunderstorms are commonplace. This will protect your electronics from most (not all) surges that would otherwise zap them into failure.

Blacked out screen


Hi,

If the power light is blinking amber – The computer is receiving electrical power, but an internal power problem might exist.

Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).

Ensure that the processor power cable is securely connected to the system board (see page 73).

flip off the surge protector and then flip it back on.

Most surge protectors only protect up to a certain limit. If you had a large surge, then i would say the power board in your printer has been zapped. I would suggest you purchase a new or second hand printer to replace yours, unless your willing to pay more than the printer is worth to fix it.
Another thought is that the problem could be the actual power point it was plugged into. Try plugging it in to another power outlet that you know is working.

Last night I turned-off my PC througg Windows and when I pushed the power button this morning nothing hapened. There is no sign of "life" from the PC.


Check the power source to the computer (both ends of the cord), if a surge protector is in line with the power , remove it and plug the computer straight into the wall. also check the wall plug with a lamp or something to ensure power there. make sure the switch on the power supply hasnt been changed to the 220v side.
If no power at the wall- check your breaker box in the house
If it works plugged straight into the wall- check the surge protector
If power at the wall and plugged straight into the computer (no surge protector) and nothing lights up when you turn it on- have your power supply checked.

Computer power won't turn on


First thing to do is try to plug the pc in another wall socket to see if it goes on, If not, the MB could have gotten fried, even though the other plugs seem to work. Hopfully you just need another surge protector as that could have gotten damaged.
