Question about PC Desktops

Acer 4062LCi Laptop (I'm a Systems Engineer) Fails to boot! Was working earlier today. POST returns 8 flashes on the amber LED battery indicator. Have been doing Windows XP updates. Task Manager shows near to 100% CPU usage with no identifiable program that I can 'End Task' that reduces it. Prior to carking it, was getting these persistently on very slow shutdown: End Program - EXPLORER.EXE End Program - HiddenFaxWindow Also with: ProcMon v1.25 02-Oct-2007 - Process Monitor Usage This program reports high CPU usage with 80% DPC's (Deferred Procedure Calls). I have a feeling these problems have something to do with the battery or with some hardware that is sending massive amounts of IRQ's.

    Acer 4062LCi Laptop Fails to boot at all! Serious Alzheimers has set in.

    After depressing the Power button, POST returns 8 flashes on the amber LED battery indicator, then goes brain dead.

    I've found various Acer BIOS Post Error codes, but none that relate to the Amber LED battery indicator.

    No point in talking about HiJackThis, as it's not getting past POST.

    Problem Solved - Battery requires replacement:

    I had that feeling something was wrong with the battery, and I was right!

    Once or twice in the recent past, I removed the battery and attempted to turn the laptop on without the battery, but it wouldn't start, so never re-attempted to try again.

    Well, it got the better of me, so I removed the battery once more, and voila! the laptop sprung back to life, what's more, the high CPU Usage I was getting while the 'dud' battery was in, has now disappeared and everything seems mnormal, so it's off to purchase a replacement battery pack.

As a systems engineer I daresay you did not use any hardware updates from the Microsoft Update page? If so roll back the drivers you downloaded

Alternatively if you identify processes that do not belong use the following program to terminate them
It is a straight-forward program called hijackthis it makes a log of the currently running processes and allows you to terminate ANY of them hence care is advised

I sincerely hope this helped

Aux power led light is amber on dimension E521

I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

Below are links and info I found from Dell's Website based on your model.

Controls and Lights Front of computer:

Power button - push button

Power light
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).

Diagnostic lights
four lights on the front panel (see Diagnostic Lights.)

Standby power light
AUX_PWR_LED on the system board

Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.

LAN indicator light

green light - Solid green indicates that a LAN (local area network) connection is established.

I am having a problem with my computer starting up. it just makes a loud humming sound when i try to start it up. the fans work but nothing else will start up.

Hmmmmmmmmmmmmmm. (sorry 'bout that--couldn't resist!)
You haven't said what model the computer is, but I'm thinking that you are talking about a desktop. I can't think of anything in a laptop that would do that.
Here's what I would do: Open the case and take a look at what fans are turning and what may not be turning. You'll have a power supply fan, a case fan (which in the Dell systems usually has a shroud that enables it to cool the CPU, too. It is possible if you have a fancy video card that it, too, will have a fan. Unfortunately, these fans are subject to early failure.
If the fans are OK, disconnect the hard drive and CD/DVD. You should get something on the display--even an error message. If you do, then plug in the hard drive and test to see if it will start.

Dell dimension 2400 diagnostic led lights abc=off,d=amber, please help
Since that isn't one of the listed codes, it is important to see what the POWER LED indicates.
If it is Flashing Amber, most likely a bad power supply
If power LED is solid amber, then either the motherboard, or a expansion card in the motherboard has failed. Remove any expansion cards, (Modem, sound or video card) try booting again.
If no Change then a motherboard

When I turn on my desktop the power button stays yellow and computer doesn't boot up.

A flashing Amber power button indicates a bad power supply. A solid amber means a motherboard failure or a failed component attached to the motherboard preventing post.

Tower power button flashes amber but will not start

Dell dimension 2350 won't boot, the psu fan comes on and the fan for the heatsink, the hard drive makes so noise what so ever and the disk drives won't open at all.

Depending on the Power and Diagnostic LED indications the system appears to be in a no post state. If the power LED is flashing Amber, the power supply is suspect. Solid Amber, indicates a motherboard problem. The Diagnostic LEDs on the back marked ABCD can give more specific POST error details.

My Dell Dimension 3100 will not boot up after I had opened the side cover to clean the interior of dirt using a brush and a vacuum cleaner. The only light I get now is an amber light on the ON/OFF button...

The first thing that i would do, would be to unplug the power cable and network cable from the back of your computer.
let it sit for about 15 minutes.

plug power and network back in. Amber usually indicates a power fault condition, hopefully you will see green now when you try to turn it on, and also see the hidden diagnostics numbers lighting up as well. (the green numbers 1-4 right above where the power button is)

If not, then with the power and network cables unplugged, give all the power connections going to your motherboard a good look over for any that may appear to be not quite seated. Gently pushing down with finger and thumb with a top down pressure (not really hard, it doesnt take much to reseat these if they are loose.
There is a wide flat gray cable that carries all the connections from the front of your computer to *********** board. this is located very very close to the power supply. try gently pushing down on that to see if it was loose. if it was removed when you cleaned it, i would pull it out again and check for any bent pins in the connector on the motherboard.

Also checking your drive cables going to the motherboard, and again applying very gentle pressure, top down.

Reseating the memory may also help but this doesnt sound like a memory related problem.

plug power cord and network cable back in.
If still no boot,
unplug power cable and net cable. then one last thing to try is removing the CMOS battery, and letting your system sit for at least 6-8 hrs. there is a jumper method of doing this but unless you are familiar with setting a jumper i don't recommend it.

reinstall your CMOS battery, plug power cable and net cable back in.
Try to power up

If you still have the problem, much as i hate to say it there is a high risk that there was ESD (Electrostatic discharge, static electricity) that does destroy sensitive computer components.

If your vaccum has a plastic nozzle, even just a split second contact on the motherboard in the wrong spot is enough to do the damage. im only putting this in as a last resort, but ive seen this type of thing quite a few times. 
If this is the worst case scenario then it would require replacing the motherboard.
hopefully this helps, and if i have helped you please dont forget to rate

Screen will not come on hard drive light no light checked power supply is ok

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

Diagnostic Indicator

Beep codes and power LED status are pre-post errors. Usually beep codes indicate a problem with a memory module. Power LED is solid green for normal operation. Solid or blinking Amber color power LED indicates a power distribution problem.
