Question about Compaq Armada M700 Notebook
I am working on a Armada M700. The battery is fully charged and the AC power supply is working properly. No lights are coming on when connected to either power source. Unit will not power up at all. Could this be caused by the voltage regulator that attaches to the board. Has anyone had this problem before? Thanks, Rockmiester
Always start with the simplest solution first so start by cleaning all the contacts, AC adapter laptop plug, laptop socket, laptop battery contacts and battery contacts. How have you confirmed power output from the AC adapter? have you used a voltmeter to ensure you are getting power at the laptop end? Have you used a voltmeter to test the battery? Assuming you have tried all this don't forget that almost any component can interrupt power on some laptops, however you're 2 main culprits with this kind of problem are usually power controller (voltage regulator) and in some cases, on a laptop of this vintage, the charge controller built in to the battery. Try it with a different battery if you have one.
