A few days ago I started repairing Laptop Batteries. And in particular the modern Smart Battery Packs. Below my first Pack opened before Repair and Reset. A BQ80201 Controller Board for the Acer Aspire 9411 AWSMi 17 inch Dual Core Laptop. Which didn’t take much time to open. These packs can’t be fixed by just replacing the 18650 Li-ions by inserting new cells like was still possible with the old Battery Packs (Mostly NiCad and NiMH Packs). Because with the introduction of the Li-ion Battery it is controlled by an intelligent controller Board that keeps track of the Battery temperature, Over voltage when charging, Over current, and prevents Exploding or dangerous Fires.

And apparently Li-ion Batteries become very unstable when they get overheated.

I encountered a lot of problems that made it almost impossible for me to repair/fix a Bad Smart Battery at first. I will summarize these points of concern below: • Smart Batteries are read and programmed by using the Philips I2C protocol.

Gaming ladder script php mysql tutorial. Hi all, once I left my laptop in standby too long(?) until it powered off with my 13 months old 9-cell lenovo battery pack (FRU 42T4644) inserted. After attaching the power cord the battery LED would just blink at a faster rate than normal and the lenovo tool reports a damaged battery. Measuring between the two outermost connector pins gives 0 Volts reading. Just before the battery would last four hours when doing normal office work.

As I'm a computer science guy and know how batteries work I opened up the battery case and measured the cells directly: all of them are about 4.15 Volts totaling 12.52 Volts. The explanation why the battery is 'dead' lies not in in the cells but in the controller circuit composed of a battery protection analog front end chip named bq29330 and battery fuel gas gauge chip bq8030DBT. Either of these chips have a FAULTY bit that can be set by arbitrary conditions.

I interfaced the battery pack via i2c and could read some data at adress 0x0b: root@raw:/home/master# i2cdump -y 0 0x0b No size specified (using byte-data access) 0 1 2 3 4 5 6 7 8 9 a b c d e f abcdef 00: 03 4a 0a 00 00 ff ff ff a4 e0 00 00 00 00 00 00?J?.??. 10: 30 00 00 ff c8 38 d7 24 e8 30 31 63 78 XX XX XX 0.?8?$?01cxXXX 20: 08 0b 04 0e XX XX XX XX XX XX XX XX XX XX XX 0b????XXXXXXXXXXX? 30: 0a 10 10 18 XX XX XX XX XX XX XX ab 13 00 01 89????XXXXXXX????

You don't need anything from Lenovo to rewrite a battery eprom. You do need the right program to support the chip.

I'm not familiar with linux and your program, i don't know its capabilities. There are a few programs that are free, but they have to support your chips and if I'm not mistaken, they only will work under windows.

I've rewritten a few eeproms, I paid for the program, (about 50USD), but it only supports chips in the x30, x31,x32, and x41. My program won't work for yours. But it does it automatically. It gets rid of the errors which shut down the battery in the first place and resets everything to 0. It also gives it a new mfgr. This assumes that the controller board is good. It's interesting that you were able to make a board that works with the VGA port.
