Hello, I have two chargers in my home that I use in my Dell Latitude E5420. One is the DA130PE1-00 (P/N: JU012) and the other is a LA130PM121 (P/N: VJCH5). My question is if they are compatible with the Dell Latitude E5440 I just got. Is there a datasheet I might be able to check? I really didn't want to use the wrong adapter. Thank you in advance, Rui
