This question already has an answer here:
My Dell Inspiron 15R 5521 charger was stolen from my University desk.
I have an old (about 4-5 years old) HP charger of my previous HP laptop.
The Dell laptop on the bottom says: 19.5V and 3.34A / 4.62A.
The HP charger says on Output: 18.5V and 3.5A, 65W.
The plug fits fine. After I plugged it in, the laptop works fine, but the battery is not charging. On the battery icon (bottom right) it currently says "Plugged in, not charging".
I have talked with Dell and they said it might pose a risk to the motherboard and that I should buy an original adapter from them.
Can I use it temporarily or is it risky? Any help?
