Thinkpad r40 processor upgrade?

[hannahhatesherself]

Is it possible or is it soldered

[hannahhatesherself]

Also if this has been posted already I'm sorry just direct me there as I am new to forums in general

[hannahhatesherself]

I think it is upgradable

[Omineca]

This Hardware Maintenance Manual shows a socketed CPU: http://tim.id.au/laptops/lenovo/thinkpad%20r40.pdf

But there must be someone around here who's actually had one of these and knows.

It is possible...however...

R40 came in two different guises: with P4M CPUs and PM Banias ones. These are not interchangeable.

If you could post the 7-character model number found on the sticker on the bottom of the laptop (which also holds the serial number and the production date) I could give you a more precise recommendation.

[RealBlackStuff]

You can upgrade the R40 with either a Pentium-4 or a Celeron CPU, depending on motherboard.
(Read the R40 manual as well).

Unless you have nothing better to do, I wouldn't waste any money on an R40.
It is not even an IBM machine, but just some rebadged POS made by Acer.

I wanna get the r40 to the best it can be because it was my first computer. I'm running linux on mine. Linux rules. As for the processor it's a pentium 4 m 2.0 ghz

I'd leave that "as-is", for the following reasons:

1) While the P4M 2.2, 2.4, 2.5 and 2.6 will work, the difference in performance will be minimal by today's standard yet the machine will run significantly hotter. There is no upgrade path for the cooling system on R40.

2) I've owned a 2.4 version - the fastest factory option - and even in a 15" frame it was hideously hot when pushed. This was in XP, I don't even want to imagine how it would be under Linux which tends to run hotter in my experience.

3) Top 2.5 and 2.6 CPUs are still incredibly expensive nowadays.

Unlike most people on this forum I have a soft spot for R40 and have played a lot with them. But apart from maxing out the RAM if you haven't done so already and getting a newer hard drive I'd leave the system alone.

[hannahhatesherself]

Can you link me to a battery for the r40 main battery and expansion bay battery. Please?

[hannahhatesherself]

Also im running peppermint OS a very lite version of linux mint

[hannahhatesherself]

Also how do I make a signature? I'm on my phone.

Like how much for a 2.6?

[hannahhatesherself]

Daaaaaaaaaang. Gonna have to call my rep payee :O dey controls da moolah

I got both now, haven't bought yet

[ajkula66]

Likely close to $100 if you can find one. Look for SL6WZ.

2.5 is SL6WY

2.4 is SL6VC and these seem to be priced around $20 which is not all that horrible.

I'm going 2.6. gotta have the best for Emily. I have to install win 98 se to update bios (plus the hdd had my cringey 13 year old minecraft let's plays).what's an iba slot?

[ajkula66]

I'm going 2.6.

Good luck.

You're much better off burning an image and updating the BIOS from the media drive instead of doing it through Windows IME.

"the diskette in the default drive will not run on this system. Your system is now locked. To restart your system press ctrl+alt+del."

What's causing this error

Wrong BIOS version ?

What happened prior to this prompt ?

[hannahhatesherself]

Installed 98se on spare hdd, burned a disk with updater on w10 (I hate it but tis a necessary evil) ran it , computer started install then errored

[ajkula66]

Installed 98se on spare hdd,

Did you do this using the R40 ? With the new drive in the main bay ?

[hannahhatesherself]

Yes I did. Then I read the controller thingy and saw that it had to be updated first so I did that but it was already updated

[ajkula66]

Sorry I haven't touched 98SE in well over a decade, can't really offer any useful advice.

Good luck.

2.6 WILL fry the system in the long term. Those chips produce so much more heat that Intel had to put more TDP rating in them, which is something they usually don't do (in Pentium III-M for example) to give you an impression that the faster chips are truly better in every single way.
I have the 2.5Ghz SL6VC part and that's already exhibiting quite significantly more heat than a 2.2Ghz part. My 2.5Ghz CPU came out of a A31p motherboard with its VRM thoroughly cooked thanks to the 2.5Ghz part.
I don't have confidence that the motherboard on the R40 would have good enough power delivery to sustain a 2.6Ghz CPU in the long run. Heck it might not even have a good enough chipset to make full use of it.
