Hi

I buy Broken Laptops and Repair them ( not all ! ) as a hobby , the question I have at the moment is that I have a Laptop repaired and ready to fire up , but I do not have the correct charger /  power supply for it .

It requires a 19V 4.5A supply , now I have a couple of    chargers but they have a 19.5V 4.5A output , would that extra 0.5 V make such a difference as to blow the Laptop ! .

thanks

No, it shouldn't be a problem.

Thanks for your reply , I am very tempted to use the other power pack's but I still need a bit more info as to whether it will be ok , I am more or less 100% sure it will be , the reason I am dithering is that I checked the Voltage of the spare power packs I have and they showed one at 19.8V and the other at 19.9V , so I am talking about nearly a 1V difference now , yes I know I should just go and buy a new one for a couple of our £s , but I like to push and try things out its just me .

cheers

Don't worry, it's normal for a power supply to have a slightly higher voltage when unloaded. If you connected the laptop and turn it on, you'll probably find the voltage drops to within 19V or so.

The voltage difference wont be a problem, but the polarity is! There are also different kinds of connectors, they look the same on the outside but the center hole is a different size. So if the pin is a thinner one and you have a connector with a bigger hole........(not a propper connection) (I assume you have the small round power plug for the power like my tablet has)
