Compaq Evo Notebook N115 Dead battery - can't charge or boot.
Posted on 2004-11-22
3 identical units. They had been left idle for several months without being used. Batteries are now dead. When AC adapter is connected to computer, there is no charge or power indicator on the computer (power light is on on the actual AC power supply), and the power button does nothing. How can we get the batteries to charge? Can the computers be operated without the battery packs?
Are these designed so that the CPU controls the charging circuit, and the CPU won't run at all without some battery power? Would an external stand-alone charger bring the batteries and therefore the laptops back to life? Is such a charger available?
