Question about Computers & Internet

1 Answer

I am working on an emachine Pentium 4 system for a client that shuts down about 45 seconds after powerup. There is no messages, in fact, there is no video or sound and the three lights on the keyboard stay lighted instead of blinking off just after power up. I have replaced the cpu cooling fan that was slow and have replaced the power supply, but nothing has made this situation any better. I also am not sure the hard drive is working because I cannot feel any vibration or heat when I handle the unit. I have removed and reseated the memory card and the video card numerous times, but still get no video or other activity. I would appreciate any help I may receive from you. My client is being very patient, but I'm sure he wwould like his pc back tomorrow. Thanks, Reg Hill

El1210-09 won't shutdown


Step 1:
Most people who own an eMachine computer will find that they will need to reset the computer at some point. It is a fact that PCs are more prone to viruses and malware than Macintosh computers. Sometimes the only way to restore an eMachine is to simply reset it. Fortunately, it is not a difficult process to reset an eMachine computer.

Turn off the computer. If the computer is in a state that it can be properly shut down, follow the normal shutdown process. On the other hand, if the computer is not reacting to anything, simply pull the cord from the wall. Restart the computer. Plug the computer back into the wall and press the Power button. Wait for the eMachine to reach the screen that reads "Press F11 to start recovery." Once this screen appears, press the F11 key on the keyboard multiple times to make sure that it registers. If the recovery screen does not come up, you will need to turn the computer off and back on again and attempt to press the F11 button again when the prompt appears. Select the proper option. After the recovery screen appears, there will be a list of recovery options. Scroll to the option that says "Full System Restore (with Backup)." Choosing this option will copy all of the contents of the hard disk to the c:\\My Backup directory. This will ensure that important files that have been created on the computer will not be deleted. However, the applications on the computer will need to be reinstalled. Allow the system restore to run its course. Depending on the age and effectiveness of the eMachine computer, it is possible this process could take up to 45 minutes. When the system restore is complete, the computer will restart itself. Reinstall applications. Any of the files created on the computer should be saved. However, the applications that created them need to be reinstalled.

Powerup problems


you should not leave PC on for more than a couple days.

It may have gone into Hibernate and if there is a bad sector, (i.e. read errors,) when that is loaded into RAM, then that can cause many symptoms. Try to boot into Safe Mode, then if that works, Restart and use Normal mode.

Bios update for t5226... intel update will not work.. some people say it is locked by emachines. i am trying to put an e8400 in it, but i don't think that the processor is supported by the older bios...


It isn't the fact of the BIOS, it's the motherboard chipset.
The eMachines T5226 uses an Intel 945G.

This chipset only supports processors with up to a 1066MHz FSB.

Supporting Data:

1) eMachines T5226 specifications;

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T5226

2) List of Intel Chipsets, and more specifically the Pentium 4/Pentium D/Pentium EE chipsets,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_Chipsets

The Intel 945G is the 12th one down, or last in the list.
Looking across to the right, you can see the Intel processors supported, and the maximum FSB support.
(533/800/1066)

The motherboard's BIOS also won't let you overclock the FSB.

The Intel Core 2 8400 has a 1330MHz FSB,

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#.22Wolfdale.22_.2845_nm.29

The Intel 945G also won't support Intel processors with the Wolfdale Core.

Lights come on but no fans or powerup


Hello,

Please follow the steps below.

1. Please removed the battery and unplugged the power supply.
2. Held down the power button for 45 seconds.
3. After 45 seconds reinstalled the battery and the power supply and pushed the power button and if it works then you don't need to replace your motherboard.
4. Else try it couple of times or up to five times before it worked if worst comes to worst.

Thanks

Compressor runs 45 seconds off for 2 minutes cycles like this no voltage change


In order to accurately determine and diagnose the problem, a more detailed description of the problem needs to be communicated as opposed to normal operation of the system so a repair person can determine that there is in fact a problem. There's a big difference between solving a problem via text as opposed to seeing what is wrong in the field. They rarely are the same.

Goodman condenser sequence of operation on a matched system. Call for cool, condenser starts, 15-30 seconds later blower motor starts, cool satisfied, condenser shuts down, 15-45 seconds later blower motor shuts down. House heats ups and a call for cool via the thermostat starts another cycle.

Based on normal operation it is impossible to determine whats wrong with the information given. There are perhaps 5 voltage measurements in the system that you could be referring to.

My Processor is switched off after switch on the machine


The CPU cooler may be stopped up-- not working. That causes the processor to shut down se-f-protecting against excess heat. Check the cooling fan first.
