spike47 Posted June 2, 2012 Report Share Posted June 2, 2012 HiI 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 ! .thanksspike Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 2, 2012 Report Share Posted June 2, 2012 No, it shouldn't be a problem. Quote Link to comment Share on other sites More sharing options...
spike47 Posted June 3, 2012 Author Report Share Posted June 3, 2012 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 .cheersspike Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 3, 2012 Report Share Posted June 3, 2012 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. Quote Link to comment Share on other sites More sharing options...
Guest alyna Posted July 24, 2012 Report Share Posted July 24, 2012 I think some store sell charger.... you can find them in any computer hub. Quote Link to comment Share on other sites More sharing options...
Trevcharl Posted October 2, 2012 Report Share Posted October 2, 2012 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)cheers Trevor Quote Link to comment Share on other sites More sharing options...
