PJP101 power jack is important. BQ24780's 15 pin BatPres and REGEN are important. Measurements were taken with and without battery. Can you check?...

You can program it with the RT809H programmer from the keyboard socket or by mounting it on the card....

Your battery should be a flat model. After changing the battery, it may ask for a reset from the bios. When you insert the new battery, you should see voltage on the connector. Batteries are sent fully charged. Can you check?...Leave a comment:

There is a diagram on the forum. The charging chip and other operating voltages should be measured.Leave a comment:

If the charge light is on, this indicates that the Bq24710 and IO circuit are working. The 3.3v line is intact. BIOS can be tried.Leave a comment:

If you removed and reconnected the LVDS socket while the adapter was plugged in, the PCH is faulty. Good evening,Leave a comment:

In some cases, it may enter protection due to the mosfet on the +19v line in the other coil circuit. You can check. If you bypass the AC input mosfet in the conduction direction -> (1N4001) you can observe the +3V LDO output.

If there is no problem with the Scl and Data pins of the BQ charge control chip, the input mosfets need to be opened. After the 19v is distributed, the LDO receives +3v and then the IO control. Then the charging should start.Leave a comment:

LENOVO THINKCENTRE M70Q NM-C61 bios problem ,
Since the mini PC that came with an operating system error could not be formatted, I decided to try the bios, I found it from a friend, it gave a writing error the last one, now the machine does not start at all, I think I need to find another 25Q128JV and write it, I think it has protection in its own bios chip, per se. Is anyone coming? -

Re: Samsung NP350V5C laptop wont turn on
Is it possible to apply heat with the nortbridge chip liquid soldering paste and BGA machine on the board? and can you read 1.5V RAM_RST voltage on pin 30 of the RAM socket,
