Does the fan run (CPU and power supply)? if so check your RAM. This is the usual cause of your symptom. It only needs one stick to fail to cause this.

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.


Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

Cpu doesnt work


Dear Zalrashdi20,
When you say that the CPU doesn't work, what happens exactly? Does it not power on OR There are beep sounds heard OR there is an error on screen that you would like to share? OR ...

Assuming that the machine is not powering on at all .. here are few checks that you would like to perform...
  1. There is a toggle switch (Voltage selector) at the back of the computer on the power supply unit, just besides where you connect the power cable .. make sure that appropriate voltage is selected.
  2. Try connecting the computer to a different wall socket.
  3. If computer is connected through the Surge protector or UPS then try connecting it directly to the wall socket.
  4. Try using a spare power cable if available.
  5. Remove all other connections apart from Power supply, keyboard, mouse and monitor and see if that makes any difference.
  6. Remove the power supply cord from the back of the computer and press and hold the power button for few seconds .. this would drain the accumulated power from the CPU components .. now reconnect the power supply and see if that makes any difference..
  7. Open the chassis and see that couple of wires run from behind the power button on the CPU to the big circuit board (Motherboard) .. make sure that the wires are properly secured.
Perform these basic checks and let me know and I would glad to assist you further.

Regards,
Srinivas

Computer will not charge or power up is their some type of reset button? The unit Model NBQ115-TS05/TS09


tried to remove battery and ac for a little while?

if that doesnt work, remove battery and ac-power.
remove the ram
put ac-power back and try to boot without ram
(do you get a beep/error?)
remove the ac again
insert the ram
insert battery
insert ac
try to boot up again.

if that doesnt work its probably a mainboard error and you need to take the computer to repair.

If that is the case your system need to check the battery for fault and does it happen with the power source too i fthe same problem check your processor fan if its bad when you on the system and is not blowing that might have cause the processor itself to get bad you will have to change this ones and then your system will be ok right rate this solution.

Power supply doesnt turn on


There are several solutions

1. Plugs should be placed correctly
2. The should be power comming into the sockets
3. The voltage switcher should be on the correct voltage... it may be on 220 V while your power in your country would be 110 V so check it

4. Fuse may be blown out

if the 3 dont work contact me again if the fuse may be blown out,, it may be a greater problem
