I’m attempting to upgrade a Lenovo Ideacentre 720-18asu to support Windows 11. The motherboard has an AM4 socket, and previously had a Ryzen 7 1700 installed. I purchased a Ryzen 7 5800x.
When I power on with the new CPU the PC does not boot – no beeps, no display, nothing. I have checked for bent pins and power requirements (PSU is 400w). Boots find if I swap back to the previous CPU. I’ve been able to find some basic specs for the motherboard, but nothing that indicates supported CPUs.
Did I get a defective CPU or is this one not compatible? Any help would be greatly appreciated!
Additional Info:
- Updated to the latest BIOS provided by Lenovo – O38KT31A
- GPU is Radeon RX560
- The legend on the motherboard beside the socket is: “AM4MH”
- The FRU Label sticker on the motherboard says: “SPP0G98417 00xK239 for MB FRU WIN DPK”
- I’ve found a few links for refurbished replacements, but none with in-depth specs: https://pcpartsoutletstore.com/motherboards/lenovo-ideacentre-720-18asu-720-series-for-amd-cpu-desktop-motherboard-00xk239.html
