I called my seller, he told me to just change year. And it worked so CMOS failure is solved. But I still get F1/F2 on fan 4 errors, he told me to disable prompt on errors but I think that's just a workaround. Is there a solution for this?
I have a poweredge R410, and I get an error when i boot up saying Hardware failure battery something. So should I change the CMOS battery? Also I get: Persistent correctable memory error rate has increased for a memory device at location DIMM_A4 But not sure if that's related but I'm changing the RAM. Also in the logs it doesn't say CMOS error because i cleared it. [IMAGE] [IMAGE]
