Power failuer when i want to use 18volt adapter of my Hp 810c printer adapter with my evo n610c, i doesnot power on?what should i do? does my printer adapter works with my laptop? plz tell me? which adapter should i use bcoz i lost my original adapter.

First off it?s a fairly risky proposition to plug a power adaptor from one device into another without making absolutely sure it supplies the correct voltage, amperage and has the correct polarity. Your laptop needs 18.5 volts, 3.5 amps, and approximately 65 watts to charge the battery. If you power adaptor is less that 3.5 amps it will shut down to prevent any damage so that?s probably what is happening. I would suggest going to the HP (now owns Compaq) or Ebay web sites and purchasing a replacement there.
