T22 LCD issues curious about pprocessor upgd

Hello all,
I am new to this list and I have an issue with my T22. It has worked great for a number of years until yesterday. Actually I noticed the monitor flickering the night before. Not anything major, just kind of like a wiggle on the lighter parts of the screen. Not the whole picture, it looked like the monitor was not getting enough power. Anyway, booting up this morning, the screen went black several times. the only way I could get it to come back was to restart. It comes up then goes black again. I managed to get into the CMOS and the flicker is in that screen to, it also blacked out. So I am sure it's not a driver issue. When the screen goes out, if you hold it up to a light you can see the objects very very faintly. I assume it would work with a external monitor, but I don't have one to check it with. I didn't have any discoloration or anything like that. It does have a few white pixels, but nothing severe. I figured by best shot was the inverter after reading here for several hours, so I ordered one and am waiting for delivery. It was only 15.90 w/shipping so I figured what the hell. I guess my question is, if it turns out to not be the inverter, is it possible to chage the bulb without totally tearing up the LCD screen and having to buy a new one? Also, just out of curiousity, whats the fastest processor that I can upgrade to? Just curious if I can or if I need to just look at a T23 or T30 when the prices drop down a little.
Thanks for an help you can give.

Hi Welcome to the forum!!

I think that you made the right move in ordering the inverter first, since there was no discoloration (ie. no red or pink). I am pretty sure that you won't have to go the CCFL (backlight) route, unless it turns out the one of the connections is going bad. The CCFL can be replaced by following along with the Sticky in the 600/770 forum. If you are very careful it can be done, but it is very tedious.

As for the processor, since you have a T22, the fastest that you can go is 1.0GHz. Chances are you have a 900MHz processor right now, so it might not be worth it for just 100MHz.

The T22 will take a 1.33GHz CPU.

Only the T20 is limited to a 1GHz upgrade.

Wow, I thought that the T20-T22 were limited because of the FSB. I didn't realize that they made a 1.33GHz to work for it.

Thanks for the replies. Cool, any anyone know what processor number that is? I am crossing my finger on the inverter. I hate to have to mess with the backlight, but if I have to I will. The worst that will happen is I will have to replace the LCD which I would have had to do anyway. But if thats the case, I am just going to get a used T23 or T30. I really like my thinkpads. I have owed about 7 or 8 of them over the years (3 currently) and they seem to be the most reliable laptop on the market.

Wrong. The fasttest CPU T22 can take is 1GHz as tfflivemb2 says.
I think JHEM is confused with T23.

Nope. The T20-22 are all mpga2, the 1.33 (and any other Tualatin CPU) are mPGA478m. All T2x series machines sans the T23 can ONLY go up to 1ghz.

further, the T20-22 all use the i440BX, PC100, and even if the CPU could fit in, the BIOS would need a microcode update to support .13um CPU's, such that the Tualatin chips are. It would also need support for 133mhz memory.

Wow, I thought that the T20-T22 were limited because of the FSB. I didn't realize that they made a 1.33GHz to work for it.

Its not the FSB, necessarily. Its the physical socket the CPU will fit it... the 440BX has been made to run at 133mhz

actually, seems that he is actually confused of what hte actual machines support... he said that hte only one limited to 1ghz was the T20...

Nope. The URL in my original reply (with a very few exceptions) is a link to the 100MHz FSB PIII CPUs that fit in the T21 and T22, NOT the 133MHz FSB PIII-M CPUs as used in the T23.

The Intel part/order no. for the 100MHz FSB 1.33GHz CPU is: RH80530GZ014512.

The Intel part/order no. for the 133MHz FSB 1.33GHz CPU is: RJ80530GZ014512.

The T21 and T22 will take a faster CPU than 1GHz, but I will also share with you the fact that you'll have a hell of a time finding anything faster than 1GHz in 100MHz FSB, they're as rare as honest politicians.

I queried Intel about this matter years ago and asked them outright how many 100MHz FSB CPUs did they build over 1GHz.

Their reply was "some"!

NB: The latest (April 2006) specification update for the mobile PIII series no longer even lists any 100MHz FSB CPUs over 1GHz, unlike the product order sheet. Plausible deniability?

James

Nope. Look at the socket type for all those chips - those labeled micro-PGA2 are ones which will fit inside a T20-22 machine. Those labeled micro-FCPGA are socket 478 and will only fit in the T23. Further, if what you were saying is true, the chip would need a multiplier of 13.3, which does not happen.

Further, the coppermine core did NOT scale to 1.33 ghz. It stopped at 1.13 Ghz in teh desktop and those were very quickly pulled due to overheating and crashing. No mobile coppermine (.18um) CPU was ever released with higher than 1ghz clockspeed.

Look at the link you posted - ANY processor labeled Ghz-M is a Tualatin core chip. The ones that are slower are all BGA and are LV chips. The faster ones are either BGA or PGA, all in the s478m form factor.

Coppermine - mPGA2, .18um, 1.75v, up to 1Ghz. Marketing name: Mobile Pentium III
Tualatin - mPGA478m, .13um, 1.35v, up to 1.33ghz, Marketing name: Mobile Pentium III-M

as far as you asking Intel, there was a 1.1Ghz Desktop Pentium III with the 100Mhz FSB. Those are hard as hell to find, yes, but they do exist. A chip over 1Ghz in the mPGA2 format does not exist, even according to your link.

The Intel part/order no. for the 100MHz FSB 1.33GHz CPU is: RH80530GZ014512.

The Intel part/order no. for the 133MHz FSB 1.33GHz CPU is: RJ80530GZ014512.

See that 512 on the end? That refers to 512kb cache. There were no tualatin chips made in mPGA2 and there were no Coppermine chips made with 512kb cache, the core would have been far too large.

edit: case and point.

http://processorfinder.intel.com/script ... CorSpd=ALL

1.26 GHZ-M Micro-FCPGA Single RH80530GZ012512 N/A

same box order code. Not all of the processors on that page are 100MHz FSB chips.

The processor finder is a good resource, but is often incomplete. The 1.33ghz P3-M in JHEM's link does not exist in the processor finder, for instance.

However, if you look above, it can be used to confirm not all those chips are 100MHZ FSB chips. All the 133's are included as well.

Ok, bear with me as I am trying to decipher some of this for myself, sorry for the hijack rattlehead.

According to this, there is a 1.2GHz that is PC100 and is Micro-PGA2. Would this work?

Holy hell, yes it would. However, that chip doesnt exist in JHEM's link, all the 1.2GHz chips are -M chips, labeled m-FCPGA/BGA and have a box order code which indicates 512kb cache.

Im willing to bet that was from an early roadmap that never came to fruition

I will concede to your, obviously, much greater knowledge in this matter.

There's a LOT of stuff like this to be found on the Intel website, probably one of the sources of my original confusion.

Yeah, my head was/is spinning. My world was nice and pretty when I knew that 1.0GHz was the limit.

No problem on the hijack. I personally enjoy this stuff. I just would like to know if its possible and what chip to use if they even make/have then anymore. That way if I get to a point where I need to do a bunch of work or upgrade I know if it's worth it or not.

Thanks for the knowledge guys.

lithium726 · #20 Post by **lithium726** » Sat May 27, 2006 6:59 pm

your best path for upgrade is going to be 1ghz. IF any other, higher clocked chips were made, you will have a very hard time finding them.

rattlehead · #22 Post by **rattlehead** » Sat May 27, 2006 7:05 pm

No problem, thanks again for the info. I'm not really interested in a 100Mhz increase, not worth the effort. My 900 is fine. I was just curious. I know SOME machines can be upgraded rather cheaply. I will let everyone know what happens when my inverter comes in.

Thanks again.

rattlehead · #23 Post by **rattlehead** » Sat Jun 03, 2006 2:12 pm

Well, the inverter cameing today and worked fine for about 5 minutes. Now, the flickering has returned. I suppose my next move is to tear it apart and replace the backlight.

rattlehead · #24 Post by **rattlehead** » Sat Jun 03, 2006 2:14 pm

Anyone know the cheapest place to get get one??

rattlehead · #25 Post by **rattlehead** » Sat Jun 03, 2006 6:05 pm

Well, I disassembled my laptop and took out the old backlight. Just to be sure I could do it without breaking the LCD before spending the money on a backlight. It all went well. I thought I had broke the end of one of the leads to the little circuit board on the back of the LCD, but it looks like that end just plugs into the little thingy and the tape goes over the whole thing to hold it all in place.. The whole thing is overall very different from the pictures and instructions for the 600 series. But, I think I get the idea. The new backlight is ordered along with the tape to put it back together. Now I just have to cross my fingers to hope it all works when I power it back up.

rattlehead · #26 Post by **rattlehead** » Thu Jun 08, 2006 3:47 pm

Well, so much for that. The light came in today. I broke the light AND the LCD trying to put it in. So now I'm screwed. Should have just went with my first instinct and just got the whole LCD to begin with. My fingers just aren't made for tiny careful work like that. Pisses me off royally. Now I've spent $35 on crap when I could have used that and been halfway to a used LCD screen. Anyone need some LCD parts?

Website · #27 Post by **tfflivemb2** » Thu Jun 08, 2006 7:58 pm

You actually "broke" the LCD?

I sympathize with you on the backlight breakage...I just broke the "free" backlight that I pulled out of a broken Dell Screen, that I was going to use in a T2x LCD....[censored] it!

rattlehead · #28 Post by **rattlehead** » Thu Jun 08, 2006 8:06 pm

I cracked a piece of the white frame. I put some glue on it. I am thinking it will be ok. I am working with the place I got the bulb from and trying to get another one. [censored] those things are freaking fragile. I barely put any pressure on it at all. I actually had it all in the frame and everything. I was pushing the small grey wire into the little channel and "tink!" snapped it in half. I really have no other options but to try again. I don't have the cash for a new LCD and I hate to have to replace it anyway if it's just a [censored] $9 bulb. [censored] those things are TOUCHY!!!!!!!!!!!! I suppose I should have tryed to find the place that sold them 3 in a bundle. Well good luck (to me too!!!)

a $9 bulb with $10 shipping.

You might want to order more than one and see if they will combine shipping.

They do. I ordered 3 bulbs, no extra charge for shipping.
