Power indicator is on but not boot - IBM ThinkCentre M52 8113 - P4 551 3.4 GHz (811342U) PC Desktop

CHECK ANOTHER WORKING HARD DISK

It seems that your first boot was on cd or dvd, or may be your hard drive did not detect, to check both of them go to BIOS set up by pressing F2 or Delete on your keyboard to enter set up. When you are in set up mode go to Boot menu (if you can not see boot menu go to advance). In a boot menu select HDD as a first boot and Cd or DVD as a second boot, if you can not find your HDD it means that your HDD did not detect, and you need to replace it with a new one.
Hope it gives you a solution

Yes,if have no power indicaton no where in the computer at all.U have power to the PC and indication of LED power light on?Yes,mean the PC have power in the system just not booting through "OS" operating system software.Try put in the original WINDOW program disc of ur Verision into the DVD drive turn computer off/on again for computer to going through the recovering bad or damages booting up sectors of the hard drive datas.

Try to go to the BIOS.If you can go there then restart and press F8 while boot and choose "last known good configuration..."

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

u may need to source a main board..and change it..hope it's still under warranty ...

If you have changed the power unit and the computer is still not powering up, then it is quite likely there is a motherboard fault - probably in the power management circuitry, which expects the power_good signal from the power unit at a precise moment in the boot up process. A fault in the power management circuitry would prevent the computer from beginning its boot-up process.

Do the fans in the power unit come on when the computer is switched on? If they don't - this suggests a power unit problem. If the power unit fans do start working but the computer still doesn't boot, this suggests either a faulty or 'dry' connection (easy checked) or a motherboard fault.

If your computer 'works' but nothing is displayed, try pressing Control+Alt+Delete. If it then boots up it suggests a power unit problem. If not .. we come back to the motherboard again.

A low wattage power unit can cause the problem you describe. Every 128 Mb of Ram needs 4 watts of power. Add more for the motherboard (up to 30 watts..) then the floppy/hard drive/dvd etc .. If the power unit can't supply the necessary wattage, it won't boot. The older 250-300 watt power units aren't suitable for modern computers with XP/Vista. Ideally, you should be looking at 400 watts plus -it will tell you on the power unit.

Though to be honest, it does sound like a motherboard fault.

The only other thing that can cause a computer not to boot up (though it will begin the boot up process) are other faults ... When you switch on does it actually display anything on the screen .. and are there any 'beeps'? 1 beep indicates everything is ok .. 3 short beeps and 1 long beep indicate a memory problem (and the computer won't boot..). 8 beeps indicate a video problem (and nothing will be dislayed on your screen). Same with 9 beeps .. which indicates a bios fault - and the computer won't continue the boot process.

If you have nothing .. no power whatsover ... it comes back to the power unit/mainboard. If you're happy that the new power unit you have put in is ok ... suspect the motherboard. If you have access to any unwanted or 2nd hand motherboard ... connect that. If your computer boots up ... its the original motherboard at fault.

Alternatively, rather than replace bits and pieces at random to cure the fault, take your computer along to a computer shop. It will take them minutes to test it for you and identify the fault.

Generally, this is an indication of a motherboard failure. Remove any items connected externally and and expansion cards intenally and see if the Power LED indication changes. if not changes, then replace the motherboard

Yes, and it may have some power problems, so check the power,battery,etc
