Computer Specs:
Dell Latitude E6420, Intel Core i5 2520M, 2x4GB=8GB RAM, Nvidia NVS 4200M, 250GB HDD, Win 7 Pro 64, Bios A23
Sata Operation set to AHCI and no fast boot. I have 3 of these computers. They are all out of Warranty.
I replaced the original 7mm Hitachi 250GB HDD for the Intel 535 240GB SSD.
I used Acronis True Image 2016 to clone the hdd to the ssd. Cloning process went just fine like on any other computer.
The Issue is that every 4 or 5 cold boots the computer cannot find the SSD. Rebooting the computer solves the issue that time. I have to find a solution. I want to sell them with an SSD and not with a HDD.
Things I have tried:
Updating Bios from A14 to A23.
Putting a 2mm spacer on the SSD and ofcourse reseating the SSD.
Swapping for another Intel 535 120GB and 240GB.
Clean install of windows which I knew was a waste of time as it doesnt affect BIOS not detecting things.
Googling the problem for hours.
Call dell?
Use another brand of SSD? It will probobly not make any difference from looking at other threads.
Use an HDD? Last resort. I cant stand the slowness of regular harddrives.
