Upgrade your Lenovo M75S-1 with the 11A9 processor.
Upgrade your Lenovo M75S-1 with the 11A9 processor.
I want to start by emphasizing that throughout my time with this machine, I have never used the built-in graphics. I’ve consistently relied on my RTX 3050 Low Profile card and kept an HDMI connection active for this project. Recently, I bought an M75S-1 11A9 Desktop, which came pre-installed with an AMD Pro 3200G. I upgraded the RAM and added an RTX 3050 to handle more demanding tasks. However, I faced some performance drops because of the CPU I chose, so I went with a Ryzen Pro 3700. All sources confirmed compatibility, and since it draws 65W, I was able to use it. After turning it on, I noticed my GPU didn’t show any output at all. Additionally, I’m missing USB power—despite updating the BIOS and resetting CMOS, the processor still won’t activate. I’m sharing this issue here as a final attempt before returning it. Also, the Pro 3200G works reliably every time (I’m using its output, not the built-in display). It seems there’s no problem with the hardware itself. Any advice on BIOS settings or alternative steps would be helpful.
It could be a Lenovo motherboard limitation preventing upgrades to faster processors. Have you looked into people's experiences online? Checking your computer's support page might be useful. Also, consider whether your power supply unit can handle the new specs. Providing more details would help further.
It seems the Ryzen PSB setup restricts the connection between the CPU and motherboard. This information comes from a reliable source discussing vendor lock-in with AMD PSB systems.
Assume your new CPU might be the issue. Would you like to test it on another machine? Or get it checked at the retailer where you purchased it?
It functions by extracting tears from poor offers. However, honestly, if the situation hasn't changed much since your last visit to eBay, you should know about the days allowed to confirm receipt and ensure the item is still valid. Based on the seller's rating, you may access eBay buyer protection by reaching out to their support team. If you paid using PayPal, you can also use its buyer protection to dispute discrepancies in the product description. Should these options not work, you might contact your credit card provider to request a chargeback, provided you meet their requirements. Keep in mind there are specific time limits for each service. It would be wise to check if a computer is available for testing your CPU—repair shops and retailers can assist with that. Good luck!
