Oh. The usual. Very dim light. Compared to TFT-screens in new machines, it had less than half brightness. Is it completely worn out, the light is kinda reddish. Actually the colortemperature drops. The tube I used, came from a TFT-unit from a ThinkPad R30. I was rather desperate, so I bought the ent...

Yup.

The backlight had worked for more than 5 years and needed replacement.
A CCFL tube is used as backlight.

Well I got the 850 MHz MMC-2 module in my ThinkPad 770Z right now, up and running. The machine was born with a P-II 366 MHz. The chipset Intel 440BX supports P-III, but not SpeedStep as an automatic feature, because of the 82371EB PIIX4E. To my knowledge, machines with 440BX/82371EB PIIX4M supports ...

The old ThinkPad 600 could be one stubborn donkey.

Take out the main battery.
Be sure, that the new CMOS battery is a CR2025 cell.

Now try and fire it up again, without the main battery.

This *should* cure any boot problems with the old ThinkPad 600.

Sharedoc. You're on

Okay. I'm taking orders and.....

Hi Prizal.

If you can wait 1½-2 weeks, I will most likely have a lot of P-III 850MHz MMC-2 CPU's.

The price will be $ 101.35/£ 52.91/€ 77.51 + shipping, prepaid.
I'll ship worldwide.

Edited, May 17 2005.
The deal is off. My supplier can't deliver.

ShareDoc. Interesting stuff 8) I wonder. In the photo, the chips themselves looks identical. The MMC-2 PIII's pinlayout is seen from the chip itself. The Micro-PGA PIII chip sits on a green PCB and it's the PCB pinlayout you see. If the chip is taken off the PCB.....wouldn't you also come to the the...

Okay. Here's the result. ThinkPad 770, P-233MMX, TX-chipset. Onboard-DIMM-0: 32 MB, Bank-0 DIMM-1: 128 MB, Bank 1-3 DIMM-2: 128 MB, Bank 0-2 Installed RAM: 294.912 KB Maximum usable RAM: 228.800 KB The 64 MB in DIMM-2/Bank-0 were ignored. Bank-0 in DIMM-0 had highest priority. Bit b0=1 disables Bank...

I got it.

Went straight into the CMOS.
Byte 2B has a value of 80 here too.

Took pictures of all 17 different screens inside the CMOS of ThinkPad 770Z with my cell-phone.

Gotta think, gotta see, gotta research, gotta.......

If Byte 2B equals Byte 43 in the CMOS Base 128 matrix, I can go looking.
Can you verify this ?

And by the way. The 64 MB modul in DIMM-0 can be taken out and replaced, when you dissamble the machine. I don't know which of DIMM-1 or DIMM-2, that swaps DIMM-0 out, when inserting a 256 MB stick, so don't hang me. Let's assume it's DIMM-1, then the following is the case. DIMM-0,DIMM-1,DIMM-2 64 M...

It was on sale on Ebay. It very rarely happens, that the MMC-2 850 MHz is for sale. If it turns out right, I will be having at least 15 [MMC-2 P-III 850 MHz CPU-cards] within a couple of weeks. When it happens, they'll be set for sale here at Wim's BIOS and the ThinkPad-forum [at forum.thinkpads.com...

It's really strange. The ThinkPad 770X/Z has 3 memoryslots. DIMM-0, 1 and 2 One of them holds the 64 MB PC66 SD-RAM Basememory in DIMM-0. This slot can't be reached, other than if you disassemble the machine almost completely. If you max the machine out with 2x256 MB in the other two slots, the base...
