Lost charger how do I find out what one to buy?

[Kikikatie]

Hi! 

I used my laptop for two years and it’s been a year since I seen it but I found it thankfully! But there’s no charger ? And I’m not sure what Model it is from HP I bought it brand new years ago in college…. How do I find and buy a new charger? And how do I know which one to purchase ?

Hi:

See if you can find a model number or product number somewhere on the notebook's case.

If you can, let me know what it is.

If you can't and you can't power up the notebook, I doubt anyone would be able to help you since there have been hundreds and hundreds of different model HP notebooks released to market in the last couple of years and they all use different chargers based on the model number.

HP (and dell) tend to use the same DC charger voltage for most newer laptop models from HP it's  usually 19.5 volts

the real issue is the capacity (watts/amps) of the charger your laptop requires

and then the charging tip (part that inserts into laptop)

as paul mentioned you really need the model number of your laptop to get the correct wattage/tip you need
