i would like to find a manual , how much and what part can i upgrade

Good evening,

Laptops, as I'm sure you're aware, are not nearly as upgradeable as
their desktop brethren, but you've listed three of the four main
upgrade areas: software, memory, hard disk, and optical drive.  IBM's
spec page for your laptop (
http://www5.pc.ibm.com/us/products.nsf/$wwwPartNumLookup/_1171340 )
indicates your given specs are correct for the O/S, memory, and hard
drive, and adds that you have a 24x CD drive.  We'll handle each area
separately below.

Software upgrades on laptops tend to be somewhat iffy.  The original
manufacturer frequently refuses to support the laptop at all (blaming
even obvious hardware failure on your software) if you upgrade the
operating system.  IBM is more helpful than that in my experience, but
it's something to be aware of.  Upgrading an O/S is not a trivial
thing to do, and I wouldn't terribly recommend it.

Next up, the memory.  You have 64MB of PC100 memory built into the
laptop (soldered in), and one memory socket that will accept up to
128M additional memory.  See Crucial Technology (
http://www.crucial.com/store/listparts.asp?Mfr%2BProductline=IBM%2BThinkPad&mfr=IBM&cat=RAM&model=ThinkPad+1300+i+Series+%28Type+1171-xxx%29&submit=Go
) for more information and to buy memory ($50 for 128MB) from a
reputable dealer.  You can undoubtedly find cheaper memory elsewhere
that will in all liklihood work as well.  This is a good upgrade to
do, as it is easy, not very risky, and will provide immediate gains in
terms of speed and usability.

The hard drive can be upgraded as well with a 9.5mm or shorter 2.5"
HDD.  You may be limited to a 32GB or smaller drive, as the laptop
seems old enough not to support larger drives.  Nobody will confirm or
deny this for me though.

The optical drive is removable, but I can find no confirmation from
IBM that it can be upgraded, though what appear to be dodgy retailers
insist tha there is a DVD drive option.  Since your laptop is
USB-upgradeable, if you have USB ports, you can also add an external
USB DVD drive, CD burner, etc.  An old O/S like Windows98 may give you
a bit of a problem with CD burning, although a DVD drive should not
cause too much trouble.  As external upgrades, these also are fairly
low-risk.

There are expansion cards for a modem, network card, and IEEE 1394
(Firewire), which your laptop may or may not have.  If not, these are
all possible upgrades as well.

Common desktop upgrades such as a faster CPU or video card are
generally not possible for laptops, as the CPUs are nearly always
soldered in, and video chipsets almost always so.  Your laptop is no
exception.  Your USB ports (if available) provide one avenue of
upgrading, as a vast array of USB devices exist these days.

The IBM Hardware Maintenance Manual for your laptop can be found
online in PDF format at IBM's website:
ftp://ftp.software.ibm.com/pc/pccbbs/mobiles_pdf/23p0894.pdf

It will be invaluable, as it covers your entire laptop in excruciating
detail for over 200 pages.  In particular, it gives instructions for
hard drive and memory upgrades.

Have a great evening, and enjoy your upgrade project!
