Not in any technical way, just from some trial-and-error experience. I had an Acer notebook that drove me nuts since a different battery occasionally made the difference -- I ended up with three -- until a new adapter/charger seemed to actually fix things...then I had to replace its power connector and all was again well for a while, and then a few weeks after that the entire machine went dead and no battery or adapter/charger could get it to start. I believe a motherboard power-card problem had been an underlying issue all along, and hopefully that will not ultimately prove to be your own case.
