Question about Acer Aspire L100 PC Desktop

Acer Aspire L100 will turns on but never boots to windows

Hello, I have a Acer Aspire L100. This past week it decide to shut off - no blue screen - just powers down. I can get it to turn on but never boot into Windows. I was able to get into safe mode at one point and back everything up. Now when I turn it on it goes into startup repair mode. Which it told me that it was not able to repair and was most likely a hardware or software issue. I tried using a restore point but no luck. So since I had backed-up my data, I tried using the Acer Recovery CD. Still hangs up and never makes it into windows. Could it be a problem with the power supply? Please, any ideas? Thank you in advance for any quidance.

Suggest you start with a basic diagnosis first, jrrjma.

1) Is the computer dirty inside? Computer unplugged from power, open the Side Panel.

[Facing the front of the computer the Left Side Panel removes. Facing the back of the computer, you will see a tab formed out of the Side Panel. There is a thumbscrew which is loosened, then the Side Panel is slid back, and up, and out ]

Is the Processor's Heatsink full of dust, etc.?

[CAUTION! Do NOT reach inside until you have followed Anti-Static Precautions!

Anti-Static Precautions:

Your body carries Static electricity. Static WILL fry out (Short circuit), the delicate hardware components inside a computer. {i.e., Processor, Ram Memory, motherboard chipset, and so on}

Computer Unplugged from power, working on a table, and computer case open; TOUCH the metal frame of the open computer case.

Make sure it is an unpainted surface.
Should you get up in the middle of working on your computer, and walk away, upon your return be SURE to Touch the metal frame again ]

Heatsink: Basic construction is a flat plate of metal, that has tall, thin fins protruding from it.
The flat metal plate absorbs heat from whatever object it is placed against, (In this case a Processor), and the tall fins absorb heat from the metal plate.

The fins radiate the heat away. With a fan used in conjunction with a Heatsink, the air flow carries heat away from the fins.

I don't know if the Acer Aspire L100 series uses a computer case fan, to push air through a plastic tuned port, onto the Processor, or there is an actual fan sitting on top of the Heatsink.

This is a basic example of a fan sitting on top of a Heatsink,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3451342&CatId=493

If the fan, (Computer case fan, OR fan on top of a Heatsink), is clogged with 'gunk', the cooling capacity will drop tremendously.

If the area in-between the fins of the Heatsink, is clogged with 'gunk', (Dirt, dust, hair, etc.), the cooling capacity will drop tremendously.

When a Processor surpasses it's thermal limit, (Becomes too hot), it turns off. (BIOS turns it off)
This is a Fail safe feature, designed to keep the Processor from burning up.

According to specifications listed for the Acer Aspire L100 series, the Processor is an AMD model. AMD's run hot as a rule, and will burn up in seconds without the proper cooling. (Around less than 30 seconds)

If the computer is dirty inside, use a can of compressed air for computers, attach the plastic straw to the nozzle, and clean the computer out.
Also clean out the inside of the Power Supply, the best you can.

[The Power Supply's case has ventilation holes in it. The plastic straw is used. Advise hold onto the plastic straw with one hand, and the can of air with the other hand. The straw can shoot off, and wind up inside the Power Supply]

Your theory of a bad Power Supply, (Weak voltage power rail), does hold some looking into, however.

{Bad Power Supply, could also have been caused by the inside of the computer, and inside of the Power Supply being dirty, too.

The cooling components for an SMPS (Switched-Mode Power Supply), are it's fan, and Heatsink/s used inside.

Once the fan, and Heatsink/s are clogged with gunk, the cooling capacity drops tremendously.

Heat = Wasted Energy

The Power Supply strains to keep up with the call for power, and eventually components inside fail, causing the Power Supply to fail }

You press the Power On button. This in turn presses against a Power On switch.

The Power On switch is connected to the 5 Volt Standby circuit. {When a Power Supply is plugged into power, there is 5 Volts present inside the Power Supply. 5 Volt Standby power}

Pressing the Power On switch closes the switch momentarily.
This directs the 5 Volt Standby power through a circuit, which excites the Power Supply, and turns it on. (No pun intended)

The first chip to receive power is the BIOS chip.

[Chip and Chipset are slang terms for I.C. Integrated Circuit. BIOS stands for Basic Input/Output System]

BIOS looks to see what devices are installed, does a Ram Memory count, Turns the Processor on, and hands the computer over to the Operating System.
{Windows XP is one example of an O/S}

In the meantime other devices are receiving power. The harddrive, optical drive/s, graphics chip on the motherboard, (Integrated Graphics), or a dedicated graphics card, and the Ram Memory modules, ('Sticks')

If the Power Supply has a weak voltage power rail, the other devices draw away the power needed to turn the Processor on.

[1) ALL the LED lights use less than 1 Watt of power

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can draw 51 to 125 Watts. Depends on what Processor it is ]

Processor draws power. Too much overload for the weak Power Supply, and the Power Supply turns off.

Either test the Power Supply voltages, or replace the Power Supply.

The latter doesn't seem like a good alternative, given the price of replacing, granted. If you wish to know how to test the Power Supply voltages, post in a Comment.

The Voltage going into a Power Supply is enough to give you a bad shock, or a Fatal one. ]
You will not be addressing this part of the Power Supply. You will be addressing the low DC voltages coming out of the Power Supply.

(A Power Supply converts AC electricity, into DC electricity. Depends on what country you are in, as to what the AC voltage coming in is.

120 Volts for the USA, 220 for Europe, 100 for Japan, are a few AC voltages used.

The voltage coming out is DC as stated.

Three main DC voltages.
A) 3.3 Volts (3 point 3)
B) 5 Volts
C) 12 Volts

Two D cell flashlight batteries produce 3 Volts DC.

(EDIT:
Always so much fun when I accidentally post a Solution as a Clarification!)

    I did clean out a lot of the dust already but I will try getting the air can today and try doing that also to get the hard to reach places.

    There are two fans with the heatsink but nothing with the power supply. This is one of those mini desktops - the plug is like a laptop one that has the big rectangular box - inside the computer behind where it plugs in is a little 1/2 inch box. Can you tell me how to check the power supply?

    The computer just never gets into windows. At one point when it was giving messages about the software I decided to just start from scratch and use the recovery CD. It will run the entire 30 minutes through that CD and never shut off but when it comes time to restart so that it can finish the process in windows it never will go into windows.

    Any suggestions?

  • jrrjma Aug 03, 2010

    checked power supply with Ohm meter - 27V

    27 Volts DC, huh?
    Hmmm,

    Okay, (Picking self up from floor), let's go on.
    Recovery Cd disk that came with this Acer?
    Did you do a Repair, (Non-Destructive Recovery), or a Full Install? (Destructive Recovery)

  • jrrjma Aug 04, 2010

    There wasn't an option on the Recovery CD - so Full Install - since it said everything would be wiped out.

I reset my surge protector and the computer wont power up. i think i need a new power supply. the power cord is working fine. Please let me know where i can find a power supply for the aspire...


The Acer Aspire L100 is a desktop computer powered by a special DC adapter and power cable. The computer's motherboard incorporates a fuse designed to prevent any power surges from damaging the computer. If the fuse burns out due to a power surge or for any other reason, the computer will no longer function. You can check the motherboard fuse for damage yourself, then take it to a trained technician for replacement if needed

Shut down the Acer Aspire L100 and turn the tower around.

Press the "On/Off" button on the front of the tower. If the computer will not boot and the fan does not turn on, the fuse may be burned out.

Unplug the power cord from the rear of the tower

Turn the tower on its side and remove the Phillips-head screws connecting the back panel to the Aspire L100's cabinet.

Pull out the motherboard assembly gently from the back of the cabinet. The internal fuse is located on the motherboard behind the DC power jack, which is to the right of the monitor jack

Let me know if this helped..

    Hi...i'm trying to boot my comp however it doesnt seem to want to get past the microsoft corporation loading screen....d2d doesnt seem to work either


    Follow the steps below,

    Step 1: Shut down your PC completely.
    Step 2: Turn on the Power button.
    Step 3: As soon as you turn it on start hitting the F8 key on your keyboard until you get to a black screen called "Windows Advanced option". (If you don't get to that that screen but you end up reaching the blue screen than that means you have delayed in hitting the F8 key. start again from step 1.)
    Step 4: As soon as you reach "Windows Advanced option" use your down arrow keys to choose an option called "Last know good configuration".
    Step 5: Select that and HIT ENTER.
    Step 6: your PC will boot to the windows.

    I have an Acer Aspire 6530 running Windows Vista and today it started shutting off at random. When it shuts off the bottom 2/3 of the screen has blue stripes across it, and on the blue is text I cannot...


    Good question.

    Does the computer feel hot when it shuts off?

    Does it always happen at the same exact time?

    Can you try booting the computer into Safe Mode? (What Happens?)

    First thing I'd try is uninstalling the video adapter driver under device manager and restart the computer.

    Let me know what happens!

    you have to restore it, I'm sorry but I haven't done it so I'm not sure how exactly to do it. You might have shut it off when it wasn't supposed to be or something. I'm really sorry I wasn't a big help. But if you can find a way to restore it, the whole thing, then you will lose everything like downloaded games, music, add ons like java and adobe. Im so sorry though. That's all I can tell you.

    Black screen after turn on


    That "Blue Screen" is also known as "Blue screen of Death".

    The problem is due driver compatibilty or unstablity.

    Try to boot your system to "Safe Boot" by pressing F8 during startup.
    Select "Last know good Configuration that works"
    Check if it can take you to desktop.
    Unstalled the wi-fi driver and reboot.

    If the above procedure fails, again
    Try to boot your system to "Safe Boot" by pressing F8 during startup.
    Select "Safe boot"
    Check if it can take you to desktop.
    Unstalled the wi-fi driver and reboot.

    Now create a restore point  and download the lastest version of your WI-Fi driver and installed.

    This should work fine.

    Otherwise Backup all your important data from your hard drive (mainly opearting system file installed drive usually C:\) and go for a new Installation.
