It has almost the same symptoms as the original dump, it turns on and off twice with a consumption of around 15W and turns off once and for all.
thank for your answer....

Good morning, please correct the original dump (with the original dump the machine turns on and off, without giving an image) or find a compatible dump.
I've already tried several dumps, with some not detecting the M2, with others detecting M2 but not detecting the dedicated graphics MX330.
The version 2.0 dumps that I tested do not detect the M2, the 6.1 dumps correctly detect the M2 but do not detect the MX330 graphics.
Thank you all....

panasonic TX-47AS650E solarized and mirror image after change mainboard.
hello everybody.
my previous post disappeared, perhaps due to the server transition... but let's move on...
I bought a similar board on ebay but this one is programmed for the 48FHD panel, my panel is 47FHD... in the service manual I can't find information on how to change it... or what to change... thank you.

Re: Lenovo ideapad 310-15abr CG516 NMA741 only power on with power supply connected,
Good Morning.
I did some more tests.
replaces bq24780 but symptoms remained.
BATT+, B+ voltages are ok, transistor PQ503 is switching correctly and charges the battery, battery has respectively G/S/D 13.6v/7.6v/7.6v, with power supply has 7.9v/7.9v/19v
PU601 and PU602 have voltages +3VLP and +5VLP both on battery and with the power supply connected.
On battery, when pressing the power button, the voltages +3VALW and +5VALW appear...
