Question about Computers & Internet

PC seems powerless except.....

One of our PC's will not turn on. So far I have opened the box up and have noticed there is a green LED light lit up on a circuit board but that is about all that occurs. When I unplug and plug back in the power cord one of the fans rotates several times and then stops. Any suggestions on where to start troubleshooting next would be appreciated.

This sounds like a short of some kind or bad power supply or motherboard.

  1. Take any components that are not necessary to boot the computer. Try turning it on again
  2. Try taking all parts (motherboard, power supply) out of the case and then put them back in (I know that sounds weird, but it has worked twice for me before).
  3. If you get to this step, either the motherboard of power supply is shot. The easiest to try would be a power supply. Replace it if you have one laying around or borrow one out of another machine for troubleshooting purposes. This is assuming they are standard ATX power supplies.

You should start with Rotary switch on "Maintenance Bypass" position and Qf1 open.
Turn Rotary Sw to "Test" position and wait for self test to execute and UPS to turn on.
Once you get the Yellow lamp lit, it is asking for QF1 to close
Once closng QF1, if green LED is lit, turn UPS off by pressing gray button until it ask for confirmation, select Yes and press Return.
Turn Rotary Sw to Normal position, press On button and the green LED will illuminate.
If, after closing QF1, the green LED didn`t lit, turn Rotary Sw to Normal, press On button and wait for green LED to lit.

Thats`it...
if anything is not working well.. please let me know.

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.

Green LED on Dell Inspiron Desktop 530 - all OK?


Yes, on most desk top the green light in the back tells you that you have power to the cpu. Even though the unit is off it is telling you that the current supply is still there. This is a good feature if you move your unit as soon as you plug it in you know if the outlet is on or not.
