Hello. Lenovo Legion 5 15ARH05H, NM-D281 Rev: 1.0 board
Initially dead. Inspection: the board was not touched, on EC IT8227E-192 2101-CXA there is a mini-burnout.
Replaced with the same one, flashed the EC with the official firmware (had to solder to the pins), left the main firmware (Gigadevice 25LB128DSIG) original.
When connecting the charger, the device started, gave picture and works, checked all the functions - ok.
Connected the original battery. Only on the battery the device starts for a second, lights up the keyboard backlight and turns off.

Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:

Minutes before changing the battery it worked perfectly and stopped working after putting the new one in. Even if you put the oroginal battery in or connect it without the battery, no LED lights up when you press the power button nor does it give an image, nor does the... -
I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.
