Jurdz Posted December 26, 2015 Share Posted December 26, 2015 Hi. Id like to know how I find out which R number my laptop is. The plate underneath just says M14x and the service tag is 506KSY1 (even dell system detect doesnt give me any further info). It doesnt say R1, R2 R3 or any other R number. Im also at Bios A09 and im fed up not being able to change anything in the bios. Is there an Unlocked Bios that I can use for my laptop?
