Upgrading RAM T490 results in black screen - machine does not boot

2020-05-16, 0:58 AM

I recently bought a stick of RAM to upgrade my T490 Laptop:

 

Crucial 16GB (1x16GB) DDR4-2666MHz SoDIMM Memory (CT16G4SFD8266)

 

However when I install the RAM, the system will not boot and results in a blank screen.

 

I even had a working stick of 16GB which also resulted in the computer not starting: Kingston KCP424SD8/16

 

I ran a crucial memory scan and sure enough it says this SHOULD be compatible.

 

Any idea when I boot my machine I only get a black screen - no BIOS or Lenovo Splash screen even?

 

My current machine has 8GB of RAM soldered on, I would really like to upgrade...

The first time you add RAM it may take longer to boot up the first time.   How long did you leave it on?  There are other posts about same thing.
