Drop down to the 'paragraph' that starts with - Travelmate 200.
(200 in Blue)
Go down to the 7th line (5730 in Blue), scroll across, and click on -
6493 in Blue.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (6493) it may take up to 30 seconds, before the first page comes up.
The file is downloading in the background.

The CMOS Battery, or also known as the RTC Battery, (Real Time Clock), is on the BOTTOM of the motherboard.

Scroll down a little to the two Large views of the motherboard;
1) The first view shown is the Bottom side of the motherboard.
Has the blue -
For Acer Travelmate 6942 6942G notebook motherboard MBTLN0B001 and tested+ree, above it.

Yes. TravelMate 6492, not TravelMate 6493. The RTC Battery is still in the same place.

Above the pink processor socket......see the Yellow round object?
It actually has wires coming from it, that end in a small white connector.
Not the same color, not the same series, but gives you a better look at this type of RTC Battery setup,

http://www.ebay.co.uk/itm/ACER-TRAVELMATE-6292-SERIES-6292-812G25Mn-CMOS-BIOS-BATTERY-/230795196555?pt=UK_Computing_Other_Computing_Networking&hash=item35bc77388b

There is a little round watch type battery in that Yellow, and that Black plastic 'bag'.

Losing date, and time? Replace CMOS/RTC Battery.
Need to reset, or wipe out a BIOS password, or HDD password?
(HarDDrive)
Not THAT way.

Go to Page 53. (Adobe Reader page number box at top)

Page 168 - Bottom View of motherboard - Number 13 in the chart -
CLRP2 - CMOS clear
(Clear CMOS jumper)

Instructions on Page 169

The Service Manual doesn't show the location of the CMOS battery.
DOES state it in Troubleshooting / Random Loss of BIOS Settings Page 148 at the Bottom.

Just an average laptop disassembly video I found. Skip to 3:40 or so to start.
You SHOULD wear an ESD wrist strap, and have it's aligator clip attached to a good ground source.
He is AT least working on a wood table top.

Perhaps some of these Acer pictorial guides will also help,

Could I be wrong about the CMOS Battery location?

Moi?

Yes.

Look down in the Battery Compartment for the CMOS Battery, or in a small hidden panel down in the Battery Compartment.
Also look on the top of the motherboard, once the Palm Rest Cover (Top Cover) is removed.


For additional questions please post in a Comment.
