Hey Guys,
I’ve had 2 of the 5-14ALC05 laptops die within 2 months of each other — both bought at the same time as well.
The first attempt to fix it was to buy an Alibaba spec board replacement, but it only lasted 1 month.
I’ve now dumped all 3 BIOS files, grabbed the latest BIOS from the Lenovo website, trimmed it to fit, and swapped over the DMI and Windows key.
All the boards did a few cycles at the start, then booted. Everything seems to be alright except the power button indicator light just keeps flashing.
