In some instances, the SSD that you buy will refuse to boot. It turns out this rare fault can be easily “fixed.”
When I received my SSD, I noticed that the sticker is not placed straight and covers small capacitors. At that time, I did not think this could be a problem and placed a heat sink on it.
After a few months, it disappeared from the boot device list. Boom. “My data is gone?” I wondered.
I removed the sticker and placed the soft stuff (thermal pad) directly on the microchips and placed the heat sink.
You can buy those on AliExpress; they come in different sizes and can be fitted in a laptop.
