Was the PC running when the storm struck? In that case changing the power supply knows as SMPS which is inside the cabinet needs to be replaced provided your monitor when independently connected to a power outlet, gives a display or says 'no video signal'...................sodeep

    I hope you recieved my answer, if not, her it is again. PC was shuutdown normally but the power switches wre not switched off. That means power was available to the SMPS only. You are lucky to have only the SMPS damaged only. Also get the fuses checked for the UPS & spike board..sodeep

A450N needs new monitor - what monitor specs are required?


Any monitor will do unless you are trying to get one with the built in speakers that you have. Just make sure the monitor has the same type of connection that you currently have (VGA, DVI, HDMI, etc).

Well I think that the console might of had been damaged by lightning thats why when theres a thunder storm you should always unplug your consoles so they won't get hit by lightning I always unplug mine when theres a thunder storm. Well the sound module inside of the console is broken then so you could send it into console solutions then they repair old systems too.

We had a thunder storm a few days ago and that we lost power and that the pc shut down by it self so the next day we try to turn on the pc so it won't turn on please can you help us


Make sure that all the plugs are plugged in. Try a different outlet, if it's plugged into a surge protector make sure that it didn't trip. Or if is plugged into a regular power strip press the reset button on the side of the strip. If that doesn't work there usually is a fuse inside the PC that might have blown.

Turn the monitor off.
Unplug it from the AC power.
Reconnect it, turn it on, and see if it returns to "normal".

HP a450n stays in a loop after thunderstorm


Hi,
This often happens during a storm and usually is quite an easy fix.
Remove the power cord, from the back of the computer, with the back of the computer facing towards you, on the right hand side there should be 2 screws top and bottom, remove these screws and take off the side panel.
Inside the case, on the motherboard you will see a large battery, take that battery out and leave it out for 30 minutes.
Now, remove the system memory, the memory will look like this >>>>>

Just unclip the memory, get a clean, dry, soft paintbrush and clean the brass contacts on the memory with that.
If there is any dust on the slots that you took the memory out of clean them also.
Wait for 30 minutes, reinsert the memory making sure it clips into place properly, put back the battery, the side panel, the power cord and power the machine on.
When the system boots up you will get a CMOS error, don't worry about that just go into the BIOS and set the time and date, save the changes and exit the bios, the computer will restart and hopefully boot into Windows.
If you need anymore advice please post back.


Good luck.

THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF


If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.
