I'm pretty sure I've to replace the CMOS battery ( orange blink 4+1 of the power led + a reboot losing the time ...)
So, beside the fact that I watched a video to replace and that it seems not so easy ! , I 'd like to know the reference or type of the CMOS battery for the latitude E5430 and where to buy it . Idid'nt find anything on the Dell support site .
many thanks in advance for any advice
