    a message came on the screen saying usb powersurge. Then the computer froze. I haven't had a power surge otherwize that I am aware of. As for the power supply fan, yes it is still working.

    Thanks for the advise, I tried that and still nothing. The computer seems to turn on, however; still a black screen.

    How did the computer show a USB powersurge? Are you aware of a power surge otherwise? Is the power supply fan (in the back of the computer) working?

    The symptoms sound like a surge damage the power supply, it's connectors, or to the motherboard. I saw the same symptoms 2 weeks ago. I replaced the video card and it seemed to work. The next day the screen kept blanking out. I pulled the power supply and replaced it. When I looked at the motherboard connectors on the old power supply 3 pins were burned. So far things are OK with the new power supply.

I had the same problem. I heard a sparking noise, then that message popped up and the computer froze. I havent been able to get it working since then. When i plug in the power source (everything else is unplugged) the power light in front as well as the LED power light on the back just blink on and off, no sounds or fan. I have tried replacing the power box, to no avail. I have also inspected the logic board for any burning or anything else that might be causing it. Please Help!!

P.S. I also have a compaq presario

I doubt if it's the monitor, but if you have a spare you should try it. Failing that, it might be time to go inside the computer. First step would be to pull the connectors going from the power supply to the motherboard. Examine them for scorch marks. If there are any, replace the power supply. Try installing another video card, if you have one. This can get expensive so you may want to shop around for a local tech with reasonable rates.

A usb power surge occurs when a usb device is drawing or providing too much power to a port. I would recommend replacement of such device before continueing. To trouble shoot what it is unplug all usb devices, start the computer, then plug devices in one by one.

It's possible that your computer froze during sleep. First, unplug the power cord, (with the cord removed) press the power button for 10-20 seconds. PS: You will lose any unsaved data prior to sleep mode. Let me know if this doesn't resolve your problem, might be something major.

When plugging my hard drive in my computor tells me that there is a powersurge and the usb port cannot deal with it ? how do I get around this ?

If you get an error message"Insufficient power to operate USB device" when you plug a USB deviceinto the computer's USB port, then this device is drawing excessive currentthat the USB port cannot supply. In case such as this, youneed to purchased a powered USB hub and connect this hub into the computer'sUSB port and then connect the USB device into this powered USB hub.

Your coin battery that powers the memory system of your camera may be failing. This battery keeps your settings and powers your on board computer. Do not confuse this with your picture battery, as that only powers the lens and picture taking ability. The coin battery holds the program. See page 38 of your manual "Replacing the Date/Time battery."

Power surge on usb hub port in compaq nc 6120

Yeah--I've seen that before and perhaps you can check it out by unplugging all USB devices and restarting the computer. If you still get that message, go into your control panel and under device manager remove all the USB devices. Restart the computer and let it find the devices again. If the problem persists, you have a motherboard issue. Might be OK, but if you can isolate the particular hub that is giving you the problem, avoid using it.

Disconnect the monitor from the tower and then turn on the monitor.
If u get a msg like no input signal or check video cable then the monitor is fine. If this is the case, it could be a problem with the tower or the cable.

Power outage last night. Deleted all saved voicemail messages. when turned on - machine says "no massages" How do I retrieve lost messages?

I'm sorry there isn't. Answering machines like this have very little ROM memory. After a powersurge and outage like last night, it wiped the whole memory chip. You can try there support page. It's actually pretty good.
