I just lost my laptop charger and I found another one on my house, I was wondering if it is compatible with my laptop and if you would recommend it using, the specs are the following:

ORIGINAL CHARGER (HP) Input: 100-240 V ~ 1.4A 50-60 Hz Output: 19.5V 2.31A 45W

REPLACEMENT CHARGER (Lenovo) Input: 100-240 V ~ 2.5A. 50-60 Hz Output: 20V 2A 46.08W

Thank you very much for your help.

The voltage and amperage are pretty much the same and it's worth giving the replacement charger a shot. As long as the shape of the new charger fits snugly (not too big or small) into the receptacle of the laptop, they should be compatible.

The BIOS on your laptop probably wouldn't like it because replacement has lower apmerage capability, but if you wouldn't load computer too much and charge empty battery in the same time, it might work. You can try, nothing dangerous while connectors are compatible (lenovo and HP has different sockets, so probably you wouldn't able just to plug it in).

BTW, HP's power supply are pretty cheap on ebay, around $6-9, just get a new one(better to look for some 90Watts, so power supply would always cover computer needs regardless loading).
