replace motherboard to get faster CPU


Aug 29, 2017
I have an ACER Aspire 5250 bz873 model laptop. I understand the CPU is soldered into the motherboard. CPU is an AMD C-50 and extremely slow. How can I find a faster CPU on a motherboard that will fit this model? I'm running Windows 10, no gaming programs. Found a report on the laptop that indicates the CPU speed is currently 800-1000 Mhz. Unless I'm mistaken, and I'm not an expert of course (72 yrs old) it seems that is very slow and processors today should be more in the Gigahertz range. Is there a site that would analyze my laptop motherboard and suggest faster ones, hopefully at a reasonable price, so I could attempt to replace the one currently in the laptop? Thanks! Ron
