Where Can I find a screenshot of the motherboard on my netbook?

http://www.fixya.com/support/t17450538-bios

There it is!

Needed to know WHAT Netbook we're talking about here.....

Problem is the info only brings it down to,.....oh,.........about 7 different Acer Aspire One models, (At 8.9 inches)
That may be a low estimate.

Akin to, "I have a Ford Ranger, and need spark plugs for it."
Question that would come back is, "What engine size is in it?"

So my question is, "What is the Model Number of the Acer Aspire One? It's on the Bottom of the Netbook."
Otherwise you get generic information...........

As asked for;

1) http://www.ebay.com/itm/Acer-Aspire-One-ZG5-Motherboard-DA0ZG5MB8F0-Intel-Atom-1-6GHz-SLB73-Processor-/111058162715?pt=UK_Computing_LaptopMotherboards_CPUs_CA&hash=item19db95141b

CMOS Battery is also known as the RTC Battery.
Real Time Clock Battery.
For the above motherboard photo, it is to the upper Left, and near the white long plastic part, above it.

Right below it is a small round Black piezo style of buzzer.
Watch style type of battery, and is either a CR2032, or a smaller style.
Believe it to be on the Top of the motherboard, if memory serves.

2) http://www.ebay.com/itm/ACER-ASPIRE-ONE-A110-NOTEBOOK-MOTHERBOARD-MBS0706001-31ZG5MB0070-DA0ZG5MB8G0-/130895071455?pt=Motherboards&hash=item1e79f448df

Left side/Middle
Usual round watch style battery.

3) http://www.ebay.com/itm/Acer-Aspire-one-8-9-A150-Motherboard-DA0ZG5MB8G0-Test-/160422303501?pt=Motherboards&hash=item2559ea170d

In photo, top of motherboard slightly off center to the Right.
Next to what looks like a small black round Piezo style buzzer.


Indication CMOS battery needs to be replaced?
Message, or Time/Date changes?
Replace the CMOS (RTC) Battery.

Trying to circumvent a password, by removing CMOS battery for a short period of time?
Don't think so. Believe there is a Capacitor, or Capacitors; that hold a trickle charge INDEFINITELY.

Suggest use an ESD wrist strap when working inside the netbook.
Otherwise you will Static shock out the delicate hardware components inside the Netbook.

Just videos that may help your endeavor,

Low battery warning message on boot up

I'll give you the info for the cmos battery but afterwards observe any other issues with your notebook. Your notebook is not new anymore and may need other servicing besides a new cmos battery.

It should be housed driectly undeneath you notebook on a panel you can remove that houses the ram.

If you still cant find it, you may have to physicaly take apart the unit. I would search under the keyboard and all four corners of the motherboard and center. Just in case.

Let me know how it goes.

P.s: Be very careful If you are not use to opening up notebooks then I suggest taking unit to a professional for them to replace the cmos battery.

Low battery alert at start up. must always type

The only battery in a desktop PC is the CMOS battery. This is a 10c sized silver disc that is held in a plastic black clip on the Motherboard. It can be clipped out and easily replaced. they are 3.6v and somewhere like Radio Shack etc. will have them.

Low battery warning

That is because while a computer is in sleep mode, it is still using power to keep the memory. The battery is only used when the computer is turned off. You should replace the battery as soon as you can in order to keep your computer running properly.
