NVRAM board replaces 5101 and 5101L SRAM chip, no batteries necessary Circuit Boards After experimentingBatteries, oh, batteries. The damage that you do. This product simply replaces the 5101 SRAM chip. You can plug it into a socket, or solder it in directly. If the socket, it MUST be a new one. This part will not repair an MPU that has other problems, or damaged traces. You must know what you are doing and have a working board first. This product also requires soldering skills. You get a 60 day warranty with replacement only.
