Same problem - green "power" LED on the MB but no activity
I'm having the exact same issue. Just to make certain the power supply was replaced. The front panel jumpers have been removed so I am trying to locate a diagram for the MB to show the jumper locations (PWR SW, HDD LED, PWR LED) next to the BIOS chip. Tested the RTC batt - 3v good.
Any other suggestions or ideas other than dump the MB and put in one that works?

Re: same problem - green "power" LED on the MB but no...
This series of machines is known for this issue. You can get a replacement motherboard for your pc from a website at www.barebonekit.com they boards run from $35 to about $65 plus shipping. This is much cheaper than you can get them most other places. We order from them on a regular basis and have had no problems. I hope this helps, if so please rate the solution.

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.
your power supply must be exact and both power connections to the motherboard must be connected. the green light will come on if voltage is supplied but will turn on a low voltage alarm which is a buzzing sound. or it just wont do anything
Steady Amber Power LED generally indicative of a failed MB. Remove all Memory, Expansion Cards, peripheral items, if still same, replace the motherboard. If you get a Green LED with jusr RAM in system, then an expansion card or peripheral might be the issue. 95% sure it is mothebroard
The UDS has the following LEDs, which help you diagnose problems. Power LED (green) Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb) Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex) Diagnostic (red) Status (green) Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status LED blinks between its pauses. The following table explains the LED functions:
If you remove all the RAM fro the system and power it on, you should hear "Memory Error Beeps" if not, then it is usually Motherboard or CPU, for around $30.00 you can purchase a PCI POST code reader to try to pin the problem down further.
I am assuming from the post that all PCI cards (dial up modem especially) have been removed. Sounds like a bad MB or CPU, but if the video is integrated,( built on the motherboard, and not a seperate card, the memory is responsible for video also, and it maybe defective.
Hi Franceso, plz specify Is it powering ON ? Which LED is glowing? These leds are there on the front panel :
1 Power On/Standby button 2 System power LED Green = Power on Amber = System shut down, but power still applied Off = No power
3 Internal health LED (Wave sign in BOX) Green = Normal Amber = System degraded. To identify the component in a degraded state, refer to system board LEDs. Red = System critical. To identify the component in a critical state, refer to system board LEDs. Off = Normal (when in standby mode)
4 External health LED (power supply) Green = Normal Amber = Power redundancy failure Red = Critical power supply failure 5 NIC 1 activity LED Green = Network link Flashing = Network link and activity Off = No link to network. 6 UID LED Blue = Activated Flashing = System remotely managed Off = Deactivated 7 UID button
If it is Internal health led then any internal h/w issue is suspected. If it is external health led then any power supply or power source related issue is suspected. Also

Logs) in ilo (Integrated Lights Out ) if it is configured. (2nd RJ45
