This sounds like either your motherboard or power supply is shot, if it is still under warranty you can get HP to send you a new power supply or send your PC back to them and they should fix it for you.
You can check your warranty status online on HP's website here.
Hope this helps.

Hi,

This mainly happens due to power outages or surges in electricity current, but sometimes for no reason.

With the rear of the computer facing you, remove the power cord. Now remove the right hand side panel to expose the motherboard and make sure you have a strong light so you can see what you are doing.

Now look at the power supply, it will be above the motherboard with lots of wires coming from it. Follow the wires until you come to a large white 24 pin block connector that is plugged in to the motherboard and unplug the connector.

Follow the wire again for a white 4 pin connector that will near the CPU fan on the motherboard (the wires if they exposed will black and yellow) and unplug that, then press the on/off button to drain any residual power.

Please note some of these connectors can be yellow in colour.

All you have to do now is plug the connectors back into motherboard, return the power cord and turn the machine on.
If it boots up the let it boot into Windows and then shut it down and replace the side panel.
If it boots but doesn't recognize any devices, perform a forced shut down by holding in the on/off button until it shuts of and the just turn it on again.

I hope this helps but if you need anymore advice please post back.

Good luck.

WHAT LIGHTS ON LINKSYS ARE SUPPOSED TO BE BLINKING


Note that incoming traffic will cause the WAN (or Internet) light to blink even if it is 'probe' traffic trying to break in to your network. Such traffic is to be expected and is the reason you have firewall functionality in your gateway router.

On the inside, there is a bit of traffic on any LAN when the computers are turned on. Messages generated by the router itself are used to find computers and printers for a lot of different legitimate reasons.

Monitor was in safe mode turned computor off and removed and replace ram. Monitor now flashing RV370 P N 113 A62801 106 BIOS not sure what to do now. to get computor booted back up


Hi...sounds like your video card has died on you. Do you have another video card lying around to swap out with the old and try?

When the video card is sending power to the monitor, the light will be green - if the light never turns from amber to green when the computer is booting, this means that the video card is not sending a signal to the monitor, probably because its toast.

Charger faulty or Motherboard problem.
You can check the power supply of the charger by measuring the DC voltage at the DC jack with a multimeter set to DC volts (red probe on the inner of the jack, black probe on the outer of the jack, should measure 18-20 volts.

Also check the security of the jack in the DC port, make sure it is not loose

See if the Ac adaptor has a green led on it, flashing LED indicates power not being "used " by the laptop

Gut instinct with this being a compaq is that the fault lies in the motherboard

No wireless connection for laptop. Linksys router - model #wrt160n v2


you can run a direct line to that router and go to the cisco web site and get the information you need to run that router. its a pdf format and is 2.56 Meg. Try this

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It

lights up and will stay orange when the Router is powered on. The color orange indicates that

the Router is not using the SecureEasySetup feature, while the color white indicates that the

Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup

mode, the Cisco logo will turn white and start flashing. After the Router has generated

the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.

To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.

The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to

indicate a successful reset.NOTE: SecureEasySetup is a feature that makes

it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's

Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.

Power (Green) The Power LED lights up and will stay on while the Router is powered

on. When the Router goes through its selfdiagnostic mode during every boot-up, this

LED will flash. When the diagnostic is complete, the LED will be solidly lit.

DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will

remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when

the wireless feature is enabled. If the LED is flashing, the Router is actively sending or

receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.

Internet (Green) The Internet LED lights up when there is a connection made through the

Internet port. A flashing LED indicates network activity over the Internet port.

Good luck

the flashing Orange and Green LED is a terminal battery failure:

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional
