IBM ThinkPad T20, Intel Pentium III 700MHz Upgrade to Pentium 4?

I own a IBM ThinkPad T20, Intel Pentium III 700MHz running Microsoft Windows XP Professional, 512MB RAM and a 160GB Hard Drive. I'm wanting to upgrade my processor to a Intel Pentium 4, 1.5GHz. Is the Pentium III Processor the same size as a Pentium 4 Processor? and will it work/Read?

    Is there anyway to get this T20 to read a 1GB RAM? Its manual says its max is 512MB. I also am going to get a WiFi card for it. Do you know if anyone has upgraded to a Intel Pentium 4 from a 3 on the T20? I want to make sure before I go out and buy a Pentium 4 Processor.

    I have the same problem> Would like to know if I can put a 512 MB or a 1 GB ram memory in my T20. Also I would like to upgrade the hard drive to something above 20 GB, but I can only find 120+GB hard drives and I am not sure if my T20 can take it.

    Thank you for assistance.

Going inside a laptop is never easy. If you can find the parts and if you do the work yourself it might be worthwhile to make these changes. If you have to pay someone it could become very expensive. Sometimes it makes more sense to put the money towards something newer and avoid the hassle.

What is the maxium upgrades that I can give my Thinkpad T20 Series 2647, from speed to memory and possible going from a Pentium 3 to a 4?


You can't upgrade the processor: it's already at almost maximum and you can't change models - different socket. The maximum RAM you can install in it is 512 MB of PC100 SODIMM-SDRAM so the speed difference will be negligible.

The IBM Recovery Disk that comes with those laptops is set up for Windows 2000, not Windows XP Pro. The answer is No, you cannot use the IBM Recovery Disk for them, if you install Windows XP Pro.

However! You will have a recovery disk, because you will have the Full Installation disk for Each laptop. Windows XP Pro Full Installation Disk.

(Microsoft Users License states "One genuine copy of Windows per One computer" That means you need Two, genuine copies of Microsoft Windows XP Pro)

Your limited with the T20 series, the biggest you can go is 1ghz. Try the Pentium M chip, make sure that it's the same mhz (frequency) that's in it now, the board frequency matches the processor frequency. (either a 100 mhz or 133 mhz, you can tell by what memory it uses PC100 or PC133)
