I cannot believe it. My Dell laptop AC/DC adapter power cord broken. I used difference laptop over 20 years: Toshiba, Fujitsu, IBM, HP, Dell. But this one make me upset. The AC/DC adapter power cord provided intermittent power to my laptop few days ago. Sometime I see the charge light on. Sometime I don't see it. Since my 3 years old battery is no longer hold the charge, I relied on the AC power. Now, I must spend an extra money for three year old Dell laptop. I don't think my next laptop will not be Dell. Period.
