Hi, I tried on upgrading RAM on my Lenovo Ideapad 330 laptop from 4GB to 8GB. Since it has only one RAM slot, I only bought one. My pre-installed RAM has specification as follows 4GB 1Rx16 PC4 -2666V- SCO-11 Samsung model, as my new one is 8GB 2Rx8 PC4-2400T-SA0-10 also Samsung. However, after I tried changing the RAM, my laptop wouldn't boot. It only powered on for around 5 seconds with no display at all and no sound was heard from the machine then it turned off completely. If I change back to my old RAM, my laptop booted succesfully. Here's what I've done
- Tried resetting the BIOS settings to default with the new RAM
- Unplugged the power cord and battery when changing the RAM, also did the 10 seconds push on the power button to discharge remaining electricity
- Tried unplugging CMOS battery also for 30 minutes
