Will not turn on. Green light blinking on back panel

Hi Bill,

The green light indicates that you are getting power to the system board, but the system itself will not start. Grab a iron or otherwise metal pot, keep it near you so you can touch it and stay grounded, and open the computer case. You will need to remove one component at a time (except the motherboard and CPU) to see if it is a faulty part that is causing your system not to boot. If you remove a part and it boots, replace that part.

Good luck!

IBMx3650 amber light appears , error indicates CPU

Most probably this would be Motherboard issue. Rare cases for processor fault. Easy to find out if server works on dual processor

Trouble shooting:
1: Perform Power Cycle (Turn off server, remove power cord from server and wait 15 min)
2: Try with minimum configuration (1 cpu, 2 ram )
(swap CPU if have dual)
3: Perform IMM update

If issue remains, replace motherboard and see if it solves issue.

I cant start my computer! when i press the power button my monitors light turns orange(from yellow) and my keyboard's light starts blinking...there comes a beep sound three times,my CPU power light remains...

This means there is some issue with your computers RAM sticks, Open the CPU and refix the RAM sticks .If you have multiple RAMs in system try to fix one and start computer.Still not working remove that RAM and fix another one. even its not working you will have to change RAMs.

The last led light blinks green and sometimes it turns solid red

red light is stands for hardware boot and the green one is stands for system boot and disc boot. when red light remains solid it means your system is in 0% cpu usage and nothing doing, stop working

There are no dashboard lights. Radio light works, dome works. nothing on dashboard except when you first start car.

when the car is first started the car will go through a light test then the lights will turn off unless there is a probem with any of the systems on the car then the light for that system will turn on otherwise the lights should remain off

Dell deminsion 3000, fans run, hard drive light on, no boot up.

Very possibly you can unhook the hard drive and cd dvd drivers then boot system see if it goes to post try and get to setup if that does not work then you system board problems or cpu problems.

No light is on but fans on

I would bet your system has been overheating - that's why it kept shutting off. Now it may have overheated and killed your CPU or mainboard. These laptops require quite a bit of disassembly to get at the CPU. You will probably have to take it to a repair shop for further work.
