Power Supply

Included with my laptop was a power supply unit with the following specifications:


INPUT:
100-240V, 50-60hz, 1.5A


OUTPUT:
19V, 4,74A


**


Now I have an old power supply from and old laptop with the following specifications:

INPUT:
100-240V, 50-60hz, 1.2A

FUSE RATING: F2A / 250V


OUTPUT:
20V, 50W Max


***


My question:
Can I use this second power supply with my HEL80? (Which has specifications matching the first power supply included with it)

Thanks

 

Short Answer: No.
Long Answer: Heck no.

Unfortunately, your old supply only provided up to 50W of power.
VOLTS x AMPERES = WATTS, so your new power supply will do up to 90W. Your old power supply will get too hot, and possibly damage the notebook, because it won't be able to supply the power it requires. You might be able to use it while the laptop is off, just for a trickle charge, but that's about it.

 

You nailed it Pitabred...there is no way 50W will drive the HEL80

 

Thanks for answers.

Now if I want to buy a second power supply, I just have to look for the same specifications or do I need the same brand?

And where can one usually buy this (I am in Canada but I ordered my laptop from the US. I would rather avoid the shipping fees and UPS custom fee).

Can you usually buy this in big box stores like Best Buy?

 

Big box stores dont carry power supplies, there are FARRRRRRR to many to keep track of.

I would suggest milestone pc since they have a canada location and sell the hel80's.

While any "compatible" power supply will due, you also have to remember that alot of power supplies have unique connectors to the laptop itself, so you may not find one for your laptop, with your plug style.

As a minor note, I would HIGHLY recommend just getting one meant for your laptop to avoid problems. Many business' and manufacturers will hassle you or deny claims if something goes wrong when using incorrect power supplies.

 

Thanks, I sent an email to Milestonepc.

 

You definitely want to buy the power supply that was designed for your particular system. A subtle difference in design or application could cause a problem down the road, and saving a few dollars is not worth the potential trouble.
