Question about Acer Aspire 5551 Notebook

1 Answer

My laptop has a loose screw or something?

My wife was using my Acer Apsire 5551 laptop earlier today, she told me she tilted it and the fan made a grinding noise. She turned it off and now there seems to be something really small rolling around in the fan or something, I shook it, but nothing came out. Does anyone have a clue what it might be and how I could fix it?

You need to tear down it into pieces to remove that object. Consult a technician

I guess I can assume that you have it plugged into the ac power, so you know its not a power problem. We also know its not a problem with the power switch since the light turns on. So that leaves, motherboard, cpu, and ram possible problems. Ram would unlikely cause such a hault. Even with no ram, I believe the computer would make horrible beeping noises. So if its a problem with the motherboard or cpu, its pretty much trash, unless you want to waste the money on ebay or some place for another cpu to try to swap.

reinstall os from shutting down in that manner he was probably in the middle of something and didnt close the program resulting in missing sys32 files which is why it wont start.this type of thing happens often and not only for that reason.
do you get anything at all on screen .
can u enter setup(bios)
try removing memory ,make sure free from dust and replace.
no screen is either missing memory,fault with hd(bad sectors)
fault with bios(hardly ever),damaged or dislodged graphics card or damaged cpu(processor)

Hello dj50551,
This may help.
Give this a try.
Turn the computer completely off, hook up the external monitor, and reboot. After bootup(and still not seeing the other monitor) right click in the middle of your LAPTOP screen, select Properties, this will bring up the Display Properties window. Go to the Settings tab(far right). Please ensure that there are two monitors that appear. You should see a number 1 and number 2. Click on #1, this is your laptop screen, and ensure that there are tick marks next to:
Use this Device as the primary monitor. And Extend my Windows desktop onto this monitor.

Then Click on #2 and ensure that there IS NOT a tick mark in the first box but that there IS one in the second.
Please reply if you require further assistance. It may be that that monitor is not compatible with your laptop. I would also suggest that you visit the manufacturers site of the laptop ond make sure you have all the latest video and chipset drivers.

It’s a very common BIOS error on the AspireOne series and it is called "Black Death" or "Sudden Death".

This worked for me, but it might not for you, so do this at your own risk.

You need:

Download all the files to an easy to find location.
Steps to prepare the USB drive:
  • Format the USB drive using the FAT file system, not FAT32.
  • Start UNetbootin and choose FreeDOS as the distribution.
  • Unzip the BIOS files and copy them to the USB drive
  • Make a copy of the BIOS file and rename it as ZG5IA32.FD (this appears to be very important)
Reflash the BIOS:
  • Make sure the AspireOne is turned off, the battery is attached and the power adaptor is plugged in.
  • Insert the USB drive
  • Press and hold FN + ESC and press the power button to turn it on. Release the Fn & ESC keys. The LED in the power button will flash.
  • Press the power button again once and wait. Mine took ~3 minutes, but I’d advise that you let it sit there for at least 5 minutes just in case your’s takes longer.
When the reflashing is done, the AAO will reboot and, hopefully, you’ll be back to normal.

If it doesn’t work, try reflashing again. The keypress sequence is very important.

Acer laptop 5551 wont charge

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

Kevin, it seems like the keyboard is bad on your laptop. If it has an extended warranty you should take it in for repair.

Did something spill on it recently or did it fall? Sometimes bumps or falls can cause connections to become loose and malfunction.

To gain access to your computer you can try a usb keyboard.

I dropped my acer aspire 5742z and now the fan is noisy and it keeps turning itself off

Fan is noisy because it is probably broken. Laptop turns off, because fan isn't working at the full capability that it should.

When a Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature built in to keep the Processor from burning up.
(Sometimes Literally!)

{The Processor is the 'Brain' of a computer. No Processor operating, no computer }

Suggest you start by replacing the fan.
(Also while you're in there clean the cooling system, and the rest of the inside of the laptop. Use Q-tips, a soft small brush, {Makeup brush?}, and a can, or two of compressed air for computers )

The cooling fan is incorporated inside a Fan Assembly.
Fan and outer shroud. (Cage)

The Fan Assembly is mounted to the Bottom of the motherboard.
This means the entire laptop has to be disassembled, and motherboard removed.

Do I think you can do it? Yes.

1) Remove ALL power. Remove the AC adapter (Charger) and Battery.

2) I suggest laying a clean, static free towel on a table, and work on that. (Prevents scratching the laptop, and the table)

3) FOLLOW Anti-Static Precautions.
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Buy, and wear an ESD wrist strap. (Electro Static Discharge)
Average cost is around $3 to $6. This is one example of an ESD wrist strap,

Connect it's alligator clip to a good ground source.

(I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
Not everyone has one of these babies laying around.

If the table you are working on has metal legs, connect to an unpainted surface of one of them.
Or use a large metallic object, and place it on the table.
Perhaps a large metal serving tray, or large metal knickknack. (Unpainted ]

4) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.

If no multi-compartment container is available, substitute with a clean egg carton. Label each egg holder. (Or even a piece of double-sided sticky tape. Make an outline, and label each area)

SOME screws look VERY similar to other screws.
DO NOT mix them up.

5) Make a record as you disassemble. Make notes, and drawings, (Legible) Perhaps also use a digital camera, or video camera. Use good lighting.

It's nice to have a Service Manual, but even nicer to have a personal record you created, along with it. Something to refer back to in case you are interrupted.

Acer Aspire 5542Z Service Manual link, (Free),

Drop down to the 'paragraph' that starts with Aspire 1200. (1200 in blue)
Go down to the 10th line in the paragraph. (5739 in blue)
Scroll across, and click on 5742G.

This model is VERY close to the 5742Z.

Also view this pictorial disassembly guide for an Aspire 5521/5551G/5551,

Gives you a hands on look at what you are about to perform.
I would also like you to scroll down to the Steps 8 through 13.
This shows more in-depth info, on how to disconnect the Keyboard Cable.

Pay special attention to the photos in Steps 11 and 12.
The Locking Tab MUST not be completely removed!
Doing so will break it, and may be a cause for motherboard replacement.

The Locking Tab only moves about 2mm, or a little more than 1/16th of an inch. (That is about the distance of this letter L, is tall )

WHEN you get to the Thermal Module;
(Thermal Module is the Fan Assembly, copper curved Cooling Tube, and finned Heatsink attached to the Cooling Tube, (and on one side of the Fan Assembly)

I Do Not believe the entire Thermal Module has to be removed, in order to replace the Fan Assembly.
The Fan Assembly is mounted to the motherboard with two screws, and should remove just by itself. (Without removing the Cooling Tube/Heatsink)

Here for any additional questions you may have. Post in a Comment.

If the installed OS of windows is not done after formatting of the drive earlier the OS may not have been installed correctly.
Secondly the drivers for the installed OS must be checked.
