Your motherboard was manufactured in late 2009. The green LED on the MB supplies DC power to the BIOS. This is known as standby. This is a relay is built into the MB maintaining the required 3 volt. When you power up the MB the power supply maintains the
3 volt DC to the BIOS. So the relay is not working. Suggest you contact Asus. All Asus MB's carry a three year warranty. Your board will need to be replaced by Asus. Call Asus at; 1-812-282-2787. (Asus Tech IL EST) M-F 8:00 to 5:00PM) There is a sticker on the LPT printer port. Write down the serial number, you'll need this when you make the call.

Good luck!
Mike

HTC increase Desire battery life.


<span>Preparing...<br />With the phone in the on position.<br /><br />Fully charge the battery with the phone on... (until the led turns green.)<br /><br />Once the led turns green, unplug the charger until the led goes off. <br /><br />After the led goes off, plug the charger back in. When the led turns green , power off the phone.<br /><br />now.... with the phone fully powered off...<br /><br />1. Unplug the charger. <br /><br />2. Wait until led goes off. <br /><br />3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.<br /><br />4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.<br /><br /><br />DO NOT DRAIN THE BATTERY. The goal is not to empty the battery and recharge like ni-cads (those have memory, these don't). These are lithiums, so we need to do the opposite...</span>

Mitshubishi plasma tv ws65869 wont start green led on in a sec off


Not a Plasma by the model number listed.

When green power light comes on and goes off a few seconds later:

Press and hold on the front of the set both the Menu and Input (source) buttons at same time for at least five seconds and let both go.

Power light will blink a two digit error code like: 2 blinks, 2 blinks and a pause and repeat it several times.

If set has been unplugged it clears the errors and you must turn on and when power light goes out repeat.

Let me know error code found and I will help

I turn it on and it comes on for a second then the goes black


You need to open it up and inspect the capacitors (look for bulging top/seal), burnt inverter transformers, resistors, etc. in the power supply/Inverter board first, post back what you find so we can guide you further.

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

Good day, seanhanna;

Hitachi has LED’s, green ‘lights’ and a red light to determine what circuit may be the problem; after removing the back of TV, bottom only, plug TV back in and observe which LED’s come on …..BUT most important which LED’s don’t come on; locate and note number, EG; DP37 and etc.

Good luck, big IRISH. Ps let me know.
