Hello, I have just registered on the forum. I have three ThinkPad X61 Tablet laptops (two 7762 models and one 7763 model with a fingerprint sensor) for which I need to replace the batteries. The three batteries I have are listed under the following reference numbers: • ASM 42T5209 / FRU 93P5032 (Le...

where are these guides man? i have two old batteries a t500 and a x61 one that don't work - can i replace some cells and make them work again? The detailed guide on how to reprogram these differs by each controller chip found in each battery manufacturer. You need to determine the FRU and your batt...

Meanwhile I managed to secure that Reserve Edition 8 cell battery, and managed to open mine up, recell it, and tested it fully working on a X61s. I've detailed it with loads of pics on a reddit post: https://www.reddit.com/r/thinkpad/comments/1m722ei/i_took_my_newly_overhauled_x61s_to_coffee_with/ E...

I still have a lot of research to do and material to buy however (as you might already noticed), the battery isn't an original one. I search a bit but didn't find articles about replacing cells for clone batteries. If it's the same or different procedures. If anyone has articles or advises it's mor...

I know the existance of these things, but I have never had the luck to come across one. I HAVE however, come across the ultra rare original 8 cell battery for these, with the flat bottom! I saw on a reddit post that these reserve edition X61s would only work with the non bottom protruding batteries,...

Thanks a lot - I am keen to learn more. By the way, did you find out how they lock-out the controller when battery is disconnected? Is there any chance to message me the programming notes (I cannot message you)? That depends on the specific battery controller. I know for the stock TI chips, like th...

I'm most interested in the 55+/55++/70+/70++ family of batteries, and the 27++/28++ family of batteries. They are used by a ton of models ({T,W,L,SL}{4,5}{1,2,3}0). While there are plenty of generic tutorials on how one should spot-weld the cells, the more tricky steps are severely undercovered: (1...

Hi me again, after using the x61t i noticed that the ram modules went back to 533 instead of the 711 that they where, i need to do the spd mod again or its a bios thing? From my experience, that wifi card connection must be very clean for the mod to work properly - Like when I tried bridging the tw...

Thanks! As a new user here I'm not authorized to send PMs yet, so I'll wait till I can. Can you recommend a way to find your mydigit posts? It seems mydigit makes it hard to search for posts on it due to a paywall or something. The PM part will be quickly sorted by RealBlackStuff. The mydigit posts...

Thank you a lot that worked, now its 2.1~2 on idlle and 45°C and its 2.4 and 70°C on stress Also, it is important to know that for L7500 equipped X61s/X61T, there are two FRU's for X61s/X61T heatsink (which are interchangable). One has a wimply aluminium coldplate and a thin copper pipe (but copper...

Hi, i tried the mod on a X61T L7500 but when i install the dw1705 card on the WLAN slot i get 4 beeps and no image, i thought that it was the middleton bios whitelist so i tried a dw1702 card on the WLAN slot and it worked. Then i tried the dw1705 on the WWAN slot and work so i dont know what could...

Hi! Do you have tutorials for reprogramming? I don't even know what software to use. :oops: Some people mention be2works, but the license costs $400. Also, I wonder if the procedure will be the same for different models, since there are so many kinds: Hi, to answer your questions: - Yes, I have tut...

T530 optical drive is just any 12.7mm SATA laptop optical drive inside some mounting brackets. You can also replace it with a blu-ray drive in exactly the same manner These SATA blu-ray drives on ebay are neither cheap nor overly expensive. But if you specifically search for a factory Ultrabay optio...

I have 2 but both are dead flat and would need re-celling (including the brand new one I bought). The laptop is 18 years old at this point - old enough to drink in some states if someone sells you a brand new one be ready for it to be dead (almost 100% guaranteed) Do you still have them? I know exa...

RealBlackStuff from discord mentioned this post to me Explain please, I am not on any discord... And I don't know you from Adam either. PS: you can now send PM. Sorry it was my fault for not explaining this thoroughly enough on Discord. I brought this post to the ThinkPad discord server's attention...

And the following is the detailed instructions on how to decipher the EEPROM of 80AF (M37516) or SL394 (AS3xxD), hand translated from Chinese into English: 1: 80AF vs SL394 share the same data storage algorithms. This being DEC to BIN, then reverse each 4 digits, and then swap the order of every pai...

I think this thread is long since overdue. After showing my experience with battery rebuilds to Thinkpad fans online, I got in touch with a fellow member who gave me a job lot of various ThinkPad batteries asking to be rebuilt. The costs, both my time involvements, and his monetary funding ended up ...

Well I replaced the CMOS battery and that didn't help. The battery I have is a 4 cell, not OEM. Has anybody had any luck opening one up and replacing the cells? Yours is 4 cell not OEM flat bottom one? If you open that up, I am very certain it's not 18650 - it's 103450 prismatic cells. You will NOT...

I know the CMOS battery is dead because I do have to enter the time and date any time I shut it off or unplug it. It runs fine and the AC adapter. I don't think it's an issue with the actual charging port because I also have a docking station and it doesn't charge when it's docked either. The batte...

I've got an old X41 Tablet that I'd like to give one of my kids but after buying a new battery and running it down, the battery will not charge. It runs fine on the AC adapter and I've tried 2 different adapters so I doubt if it's the adapter or charging port issue. I've removed the IBM power manag...

The FRU is: 93P5032. The cells are a dark burgundy red. And it does have a BQ8030 chip on the board. And I do have Arduino boards, but I can get a CP2112 pretty easily. So indeed, Sanyo with BQ8030, which is a Sanyo firmware chip (TI merely made the chip hardware, shipped to Sanyo completely blank)...

I also have a X61T (tablet) that I recently acquired as a "For parts only" unit. Repaired it, but the battery pack appeared to be dead (battery LED on laptop is flashing quickly). I found this replacement on Amazon: https://www.amazon.com/dp/B09PL9TZTX?ref=ppx_yo2ov_dt_b_fed_asin_title Haven't rece...

I've re-edited my first post so it's not keeping such a narrow lane. I wasn't sure about mentioning non-Thinkpads here but the more I read people's posts, the more I see that some folks do deal in general computing but their preference may be - but isn't exclusive to - Thinkpads. Thank you folks fo...

There is also a similar problem with using the power supply of say a ThinkPad 770 or 600 on a power hungry beast like the A31p or T43p. All of these have the same connectors. And unlike newer Lenovo ones, or Dell chargers, there is no sense pin telling the computer what wattage is available for use....

IMHO your best and most reliable W98 Thinkpad would be a 15" R52 with SXGA+ and Intel graphics.

Has anyone even managed to get the GMA 900 working in Windows 98 at all? I always assumed that the GMA series all have no Windows 98 drivers, only the Extreme graphics do.

I am on a Linux machine, and I tried to create a bootable Windows Vista USB without any luck. What I tried so far: - Create a USB drive linux installer just to make sure the x61 can boot from it. Succeded with no issues. - Create a Windows Vista USB drive using WoeUSB-ng [1]. The USB drive does not...

Do you still have units available, I'm looking for a way to reprogram bms for X240-X270 series Thinkpads. Thanks! I can send these kits, but I do not have anything of that age, so as for the actual unlocking tools you may be on your own. There are guides on youtube talking about the BQ900x found on...

I’m in the too new here to PM boat, but I’ve been hunting a good x60/1s for a few months now! If you’re still looking to sell either, can I ask for more info about them? Alright, then I guess I will list down what I have with these then (all 3 have Lenovo badges and Core 2 duo L7500's): X61s #1: FS...

Bump, with 7 units remaining.

Due to interests from fellow fans, I end up used/reserved almost all my 18650 cells for various ThinkPad rebuilds. Only the following are for sale: FRU, original maker, Design Capacity, tested full charge capacity, cells used, remarks, price (Canadian dollars) ThinkPad T61: - 42T4623, Sony, 57Wh, 62...
