I have a compaq presario500 when I plug in the power cord the power light automatically starts flashing rapidly. Then when i press the power button it flashes several times and shuts off with nothing previously starting up like the fan or the hard drive.I removed the battery along with the power cord and pressed the power button down for more than 20 seconds. Also moved the ram around. What can posibly be wrong?

switch off you printer. pull out power cord from source, wait for 5 minutes then plug in back the power cord to the source and switch back ON your printer

unlikely as it seems to use blootooth technology but doesnt expose the passcode for the connection. see below.

How do I pair my headset to its USB adapter?

Procedure

Your headset and adapter are already factory pre-paired, and should automatically connect with each other. Should your headset and adapter become unpaired, you can initiate pairing manually. To Pair Your Headset and Adapter:

1. Start with your headset powered off. Press and hold the power button for about 4 seconds, until the status light rapidly flashes blue. Release the button and set the headset aside.
2. While the USB adapter is plugged into the computer, pinch the connect/pair button for about 4 seconds, until the status light rapidly flashes blue. Release the button.
3. The headset and adapter will automatically attempt to pair. If the pairing is successful the status lights will glow solid blue; if unsuccessful, both headset and adapter will stay in pairing mode.

If the pairing was unsuccessful and you want to try to pair again, you must first take your headset and adapter out of pairing mode:

1. Turn your headset off.
2. Single press the connect/pair button on the adapter.
3. Repeat the "To Pair Your Headset and Adapter" procedure, above.

If your headset and adapter are separated and lose their connection after being successfully paired, they will automatically reconnect when they come back into range of each other. If they remain out of range for more than 30 seconds, the headset will go into sleep mode, but will reconnect automatically with the adapter once it is back in range. If the headset is out of range for more than 15 minutes, it automatically shuts off.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.


Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

I'm afraid you need a new Power Supplies Unit. Just try an old trick first. Remove power cord from the back of PC. Press power button and keep it pressed for good 30 seconds. Then reconnect power cord and try to start as normal. If this don't work I'm afraid your PSU is dead. Good Luck

This sounds like a battery problem. The best way to test this is to remove the battery and then power the laptop up with just the power cord plugged in but no battery. If the computer boots then the battery is bad you will need a replacement. Also try letting the battery charge for a day. Be sure that the charging light is coming on when you have it plugged in.

Press the Start button for five minutes automatically the system will turn off..
Or else u can can restart the system..

Hello! Try this:
1. Unplug the power cord

2. While pressing the ON button, plug the power cord back in.
The power light should flash an orange/yellow color.
Continue pressing the ON button, and press the RESUME button 4 times. The light changes every time you press it.

3. Release both buttons, and restart the printer.

The printer should now stop blinking and operate as usual.
I hope this works for you. OMS
