Unit wont boot/power up

My unit won't power up. I got up one morning try to boot the system up and nothing. I purchased the unit in October of 2004, never had any issues with it, the unit is used mainly for music production; with a keyboard, and an interface unit. I have Pro tools, and Logic installed, with an occassional external drive added.

When you state it wont power up do you not get any lights at all when ya press power button?? If you get the white light when ya press power button???? If you are getting a lite from power button then you may need to just reset the PMU on the system board IF you are not getting a light then you will need to replace the power supply.

It could also be a bad power supply. Mine went out a year after I purchased it, and I found that this was a known issue with some Power Macs. I had to ship it off for repair, but it was recovered under warranty (minus shipping).

Is this a G5 2.7, dual 2.5 with a multicore processor using a liquid cooling system? If so open the case and check to see if any liquid is actually leaking. See xlr8yourmac.com for a whole bunch of postings on the issue.

The TPMS has to be reprogrammed to see the new unit in the tire. There is a special tool that does that and KIA is a car brand that has a proprietary system. Take it to a dealer and have it done and no it is not free. Take the bill for that to the tire company and see if they will pay you back.

System unit or power supply?


The computer power supply may have failed. Do you get the "post beep"?

If not- remove the BIOS battery, move the jumper to "Clear BIOS" . Insert BIOS battery, and try to boot. Put jumper back to normal position and try boot again. If you do not get the post beep, swap power supply for a known good one, and try boot again. If it still does not boot and give you a post beep, look to see if there is a removable BIOS chip- pop it out and put it back in.place, this will clean the terminals. Go through and reset BIOS, as above, and try boot. If the system is functional, it should now boot up, but prompt for you to run the setup program.

If it does not boot, the problem is relating to motherboard/processor.

Hello,
For your system to boot up properly, you need an identical power supply for your system. Most likely the reason why your system won't boot up right now is because you purchased a different power supply and it is lacking something(which is the other pin).

If you just purchased and it won't turn ON, don't waste time trying to fix the unit. Return it to the place of purchase for a replacement unit or a refund.

Unit is switching to battery power for now reason.


Any UPS monitors the incoming AC level to determine if it is needed or not.  I think the APC unit doesn't know any more when it is needed; it's sick.

GPS V plus. Screen goes blank except for one thin horizontal line. Unit becomes unresponsive. Have to pull the batteries. After that the unit restarts and resumes working as if nothing had happened.


According to Garmin Tech:
01) Power unit ON
02) Press ENTER until you get past all the warning screens
03) Press MENU twice
04) Go to SETUP
05) Under the SYSTEM tab, goto lower right box labeled WAAS
06) Disable the WAAS

Hope this helps!!!
