Review on A-Tech Laptop Memory Upgrade Module - 16GB DDR4 2400MHz SODIMM RAM (PC4-19200/PC4-2400T) CL17 2Rx8 1.2V Non-ECC - Notebook & AIO Computer by Doug Cardello

It is supposed to work on my laptop. Exactly the same specs for my laptop. Tried the same issue on another laptop. never worked The laptop just beeps and won't turn on. Called support, no answer. I left a message they never replied to so I returned it the next day. I ordered from another provider. I bought two memory cards from the same seller with the same problem. I think they were used or the specs are wrong there. Do not buy! DOA. By the way, I've been an IT guru for 25 years, so I definitely know my way around the PC. This is my field. I build computers from bare bones to fully functional devices.
