Question about IBM ThinkPad T20 2647 Notebook

IBM Thinkpad T20 Type 2647

I am upgrading the RAMM to 512mb over two slots and am thinking of increasing the hard drive from 12gb to 20 or 40gb.
I would like to run Windows XP Home on this but note that minimum system requirements are 300mhz processing - machine currently fitted with PC100.

Can anyone give any advice on this? - can the processor be upgraded on this model to accommodate or are there other workarounds that can be used?

Re: IBM Thinkpad T20 Type 2647

I currently own 3 Thinkpad T-20 Laptops. They all have a 700 mhz processor in them, and so will yours, more than enough to run windows xp, in fact, I am running Windows XP Profession on one of them. The PC100 is the type of memory it uses, not the processor speed. i recently installed a 120 gb drive in one of them so you will have no problem installing a 20 or 40 gb drive, or larger.

I would like to nwom how much of memory this laptop support

The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.

Thinkpad T20 won't accept memory upgrade

according to ibm
you are allowed only pc100 memory with a maximum of 512mb.
when handling memory make sure you are grounded before touching any memory chips.
try getting another set of 256mb chips and grounding yourself before installing them.

Where is the hard drive located on the think pad t20?

It is a slot on one side, held by one screw.

Unplug laptop and remove battery.

After unscrewing, slide down and then pull out the plastic cover toward the side of the laptop. You will find attached the hard disk caddy.

You will need to remove the hard disk from the caddy by undoing four screws.

Processor and Disk space

The biggest processor available for the T20 is 1ghz. Be sure when replacing the processor that you get an IBM 133mhz processor. The memory is 1g max, the machine will hold two 512mb chips, and be sure that it's PC133 memory. You can put up to a 120g hard drive in the machine, be sure the hard drive is an IDE 4200rpm drive. These are the specs for the T20, and the maximum size this machine will hold. You can go to this max or anyplace in between.
