I think i may have broken my school laptop

[OldFord76]

So I have a Dell Latitude 3300 laptop issued by the school district for my classes. The charger cord is the kind that has the brick and part that goes to the computer on one end, and a detachable part that goes from the brick to the wall outlet. A bit ago i somehow broke the part that went from brick to wall, so i grabbed one that went to an old monitor. Well now, the laptop dies literal minutes after being unplugged, no matter the battery level. I looked and th new cord says 300v and the brock says "Input 100-240v" 

 

Did i like overvolt the battery or something? I've had this same laptop for like 3 years now. Could it just be age? I'm not sure if ill have to pay to replace the laptop or what

 

Edit: im posting from sed laptop and it works as normal plugged in. As soon as i unplug it, it like locks down and i just wait for the light to go off then turn it back on, get a "battery critically low" message, and it usually lasts like 20mins on "0% battery" no matter if it was at 100 or 5% before i unplug it

Nah the cord is just a rating, it ultimately just delivers power from the wall outlet to the brick. You need a transformer to ajust voltage by that much which is what that brick is for, it wouldnt fit inaide the cord.

Using it for 3 years might be enough to make the battery not work anymore.
As leaving it when its connected to wall-power for prolonged times isnt the best and draining it till fully empty and leaving it so also is bad.

But by the sound of it the new cable works fine.
The 300V just means its rated 'up to'. So 100V-240V is way under it and fine.

 

 

edit:
Yup, sounds like the battery has had a long life. Sorry, but they just dont last forever.

the number on cord its just the maximum it can goes down. usually happen in blink of eye. so no probably just some normal battery problem

Sounds like you have a dud battery. Changing the cord between the power brick and wall won't affect that, because the brick turns any AC power around the world into the right DC power for your laptop.

 

Check with your school to see if they'll give you another battery. If they're still the school's property, they should be covered by a warranty or support contract.

Thank y’all for the help. I hope I can get a laptop used for kinda cheap, the school laptops are the worst. But let’s be honest with my budget I couldn’t get anything better lol. I should be able to get it replaced free anyway
