The command however is not writable. Reading it returns. Ok, nothing straightforward. Chemical reactions and chemical reactors george w roberts solution manual. No obvious BOOT pin as one would expect with a device that's not meant to be tampered with.

But maybe pulling some pin high or low during reset will get me somewhere. After the first pass no, not really.

Sanyo Tool Reset Bq 8030. So the battery of my DELL XPS17 L702X suddenly died and that really sucks. Dell wants to get 150+ € for a new one and i don't have that money as a student at the moment. Sanyo Tool Reset Bq8030 Datasheet. Battery capacity is stored as the remaining capacity reported through SBS divided by 2. Cycle count is stored as Cycle. Count- 1 (eg.: SBS value: 2. Eeprom byte: 2. 22)Remaining Capacity Alarm is stored as- is. A good place to start mapping. It's a good idea to reset the cycle counter.

So maybe we have to set multiple pins into multiple states for it to work. Or maybe there's no such combination at all. How about I try to abuse N/C pins instead. I have no logical explanation as to why I came to this decision. Maybe I saw a presentation somewhere about blackbox chips and N/C pins years and years and years ago but I could just be imagining things.

Either way, about 5 minutes of poking at PIN #28 with a resistor connected to 3.3v in hand and triggering RESET at random intervals while running a continuous command scan. $ smbusb_scan -w 0x16 ------------------------------------ smbusb_scan ------------------------------------ SMBusb Firmware Version: 1.0.1 Scanning for command writability.
