Hi Pfudaniel,

Has your MSI Laptop become operational after you've changed the chip? I have the same problem with my MSI GF63, that same chip IACEK is burned and wont power on. Is IACEK top marking the same as MP2143DJ-LF-P (from the link you shared). It looks like this chip is a buck converter (Switching Voltage Regulator) which is capable of generating fixed output voltage ranging from 600mV to 5V with Input voltage of 2.5V - 5.5V. May I know where did to bought the chip? Thank in advance!

The parts are the same as shown in the Mouser link. The date code varies but otherwise the same.

You can also find the part on AliExpress.

Search for 'MP2143DJ' for the keyword.

Hi mon2,

Great I found the chip online in my country and its super cheap...
Thank you guys....

Actually the TOP MARKING means as follows:

IACEY (first digit is not actually letter I, but I dunno what does it mean...I'm guessing it's just a marking separator or something)

ACE: product code of MP2143DJ;
Y: year code;
So meaning the last digit doesn't really matter coz it's only a production date.

I was fixing the same laptop today. Symptoms: there is no reaction to the power button, but the battery is charging. I found this chip labeled |ACEM, the chip was damaged. I took it off, disconnected the display cable and connected an external monitor via HDMI. The laptop turned on, the system booted up. It remains to find a replacement for the chip and check how it works with the native display.

I replaced |ACEM with |ACEE, the laptop is working. Victory!
