I often used your wonderful blog in the past years, and this is my first topic. I have an old (2012) Sony Vaio SVE1511P1EW, Intel® Core™ i5-2450M Processor 2.5 GHZ, 4 GB ram. I have recently decided to invest some money to upgrade it, and I doubled the RAM adding a new 4 GB batch ( current total ram = 8 gb), I installed a SSD Samsung 85EVO 250 gb and I upgraded to windows 10 PRO.
The laptop worked wonderfully fine until few days ago, when I tried to switch it on as usual: leds of battery and system were normally blinking, but HHD led was exceptionally blinking slow and repeatedly. I plug the battery, plug it off, test the ram ( try each one separately ect as suggested in many different discussions I found here) but situation didn't change. Fan goes on for a second, then all leds go off, then fan goes on again and leds blink, then it all goes off again. It's like the "miss some sort of bios start-up procedure3.
I then though about the possibility that the new SSD may be corrupted: i then took the hold HDD (on which i still had the operative system), plug it inside and miracle, IT ALL WORKED! I therefore ordered a new SSD, but in the meanwhile i tried again to switch the pc on and, again, NOTHING WORKED.
I finally tested the SSD on an external drive case, and it worked perfectly. So the SSD isn't corrupted.
Any idea suggestions?
thanks a lot for your time!!
