Acer Extensa 670CDT Where's the repair manual (not just a user's manual)?

Sorry for posting again, but it has been three weeks, and only two
suggestions to fix this nonbooting notebook. One suggestion was to take it
in for servicing, and the other to disable the mouse in the BIOS setup.

Does this notebook require a good batter even though it is plugged into the
wall outlet with an ac adapter? I'm thinking that maybe this brand won't
boot without a good battery, which this one is dead, but plugged in anyway.

   Acer's support page for this notebook (They bought Texas Instruments

    The Acer technical articles (all three of them) don't help me boot this

    I've already got the user's manual and specifications notes, but these
stop short of explaining what to do with a non-booting machine, other than
"take it to a service person". I don't mind disassembling the notebook, if
that is required to
fix it. Maybe a loose wire or component? The note book does access the
floppy, CDROM drive, and hard drive, when setting any of those first in the

Here's my boot screen:

I'm not sure which error the owner's manual startup errors best describes my
boot error. The last message to display says "Press <F2> to enter SETUP",
but pressing F2 does not allow entry into the BIOS. To do that I must reboot
and hold down the F2 button. The clock battery keep time. Today it says
04/12/2001, and the notebook hasn't been plugged in for about thee weeks.
The BIOS is not locked, so I have tried these senarios:

Set BIOS to boot CDROM first--but that didn't work with either Win98 or
Set BIOS to boot floppy first--that didn't work either with Startup or Linux
boot disks.
Set BIOS to boot the hard drive--put in a working Linux/Win98 dual boot 6
gig drive.
    (The BIOS recognized the drive, accessing it also on boot, but still
hangs at
    the same spot above).

Here's the official Startup Error Messages from the  user manual:
Disk drive A error

Failing Bits: nnnn Fixed Disk 0 Failure

None of the above error display on the screen. The CD drive is spinning up
now with the bios set to boot CDROM first. Seems to spin for about 60
seconds then stops.

Any help is appreciated!

Acer Extensa 670CDT Where's the repair manual (not just a user's manual)?

New question!

Okay, after the keyboard and static shield it appeared to be a loose
touchpad cable ribbon attached to the motherboard.  Snapped the cable snug
and it boots! I guess I was wrong about that technical article. Now that the
notebook boots I've got to reset the hybernation with pfdisk, or lpfdisk.

Can I upgrade this Extensa 670CDT with a faster Pentium than this 166 MHz? I
see jumper settings for the CPU and it is removeable. What's the fastest
this thing can run? Can I pop in  a mobile K2, or  PII?

1. Motif Programming Manual and Motif Reference Manual by O'Reilly now free

IST is pleased to announce that Volumes 6A and 6B of the O'Reilly
Associates 'Definitive Guides to the X Window System' series of books
are now available for free, direct download in various formats and
contents from IST's web site.

Volume 6A is the Motif Programming Manual.
Volume 6B is the Motif Reference Manual.

The versions that can be downloaded from IST's web site are later
versions than those made available by O'Reilly themselves. In
particular, Volume 6A from IST is for Motif 2.1, whereas from O'Reilly
it is for Motif 1.2.

Antony Fountain and Jeremy Huxtable of IST have completely overhauled
Volume 6A, Motif Programming Manual, for Motif 2.1. This online
edition is the first publication of the Third Edition, dated December
2001, and is the authoritative 'how-to' work on Motif 2.1. A printed
edition will be available from IST in due course.

Volume 6B, Motif Reference Manual is also available in updated form
online. This is the Second Edition of 6B, dated February 2000, for
Motif 2.1, as revised and updated by Antony Fountain. The online
edition has been augmented with a number of patches and the sections
on UIL have been re-instated since the last paper publication of the
volume. Volume 6B is the standard reference work on Motif 2.1.

The versions available from IST are available as both PDF files and
source files for UNIX FrameMaker 5.5. Those available from O'Reilly
are in troff format, and exactly match the last paper publications.
