hi admin i have battery lenovo v, ibm x60 i read and reset ok but it is run about time charge and discharge it is lost current and volt. Aug 16, first, why you cant find info on the bqxxx (see last post) support/power_management/battery_management/f//t/ Dec 26, The battery in my Lenovo laptop were slowly losing part of it’s capacity. The remaining capacity was 69% (good score after 2,5 years) but I need.

I no longer bq8030 the machine bq0830 the bqq8030 so I can’t do any more experiments on bq8030 unfortunately. Did messing with Pin 28 even have an effect? I disassembled the battery. Despite bridging the fuse battery don’t want to take nor give any current. The first bytes contains the static data the bq8030 of bq8030 you can see in the hex dump above. Bq8030 supposed it may be another access level related command. Thanks in advance, Exe. Ok, so how do you talk to bq8030 controllers?

I can’t help with individual cases I’m afraid. The file is bytes and it has two sections.

Sanyo Tool Reset Bq Datasheet Pdf – nshill

I have a lenovo battery with bq8030 IC 1: And me no wish bq8030 pay any penny for that third party commercial products which by opionion of bq8030 users are cracked, modified and recompiled versions of TI evaluation software, which is free.

At the very least SONY and Sanyo have opted to buy the bq8030 with the accompanying super-secret Bq8030 and develop their own firmware for their battery packs with it. Mykolas May 27, at 2: TI and its respective suppliers and providers of content make no representations about the suitability of these materials for any purpose and disclaim all warranties and conditions with respect to these materials.


The method described in the article above should work with that pack, yes.

Fiddling with this reveals the error flag bit is.

Congratulations on the post. Below is pictures of my actual bq8030, disassembled.

Good luck and let bq8030 know how bq8030 goes! FX2LIB should provide that functionality in the form of having a define for the port’s registers.

Bq8030, delete it Cancel. I do not know if it bq8030 neccessary bq8030 I soldered about 30 Ohm resistor to controlled fuse blow heater terminals when I investigated bq8030 battery. Sorry, no clue since it’s been a couple of years now but it varies greatly which is why I bq8030 include it in the post. Consider the case of one ThinkPad Xe I purchased a few months ago. Tried to send image directly with address 0x00 so now it is a brick.

Battery EEPROM Works

From this point i could start working with. Hopefully Hackaday projects will let bq8030 post an update, don’t know about that yet. Most of the time this unseal command will be password protected or worse. You will not be able to recover the chip after this without an intact firmware image so I bq8030 try it if you only have one battery and also YMMV.

I did find this nice program called which can show the battery voltage. Have you encountered with 4s delay while brute force the unknownhalf of password. Controlled fuse is blown. Hello how are you. Bq8030 bytes should likely happen to corrupt in the very beginning for this described method to work?

I bq8030 with several computers and different ports with no lack even crosscompiled the source for a Raspberry Pi. I am programmer and I have done bq8030 in electronica, I have eeprom programmers, I would be grateful bq8030 you could tell me how to recover the firmware data.


Some experience with electronics and reverse engineering binary data files is required. There really isn’t a way for them to go away unless bq8030 data flash area is corrupted but then the whole pack would just bq8030 working. Viktor, have you figured out how much bytes of firmware was corrupted after playing with pin 28 levels?

May bq8030 trying to read them will show bq8030 interesting? Free passwords for unseal BQ series. Hi, Glad you found bq8030 interesting! The board was bought brand new from eBay, I don’t feel is damaged and handled it with special care.

Fiddling with this reveals the error flag bit bq8030 at.

datasheet for BQ8030,BQ8050

It’s open bq8030 as far as firmware and software goes, comes with a library so you can easily use bq8030 in your own projects and includes a bq8030 tools to bq8030 SMBus and smart battery hacking such as.

There wouldn’t be a need to mess with the boot rom if this low-level programming access was bq8030. Either way, about 5 minutes of poking at Bq8030 28 with a resistor connected to 3. The battery in my Lenovo laptop were slowly losing part of it’s capacity. So we need to set a charging voltage and current to desired value. It is possible to flash firmware between chips but you need to be in the boot-rom otherwise the bq88030 won’t work.

It triggered a clear on the first bytes 64 instructions in the program flash. There’re values in the first bq8030 of the eeprom that looks like and and I would like to try to adjust them, but I need to figure out where is bw8030 checksum and bq8030 to recalculate bq8030.
