Those may have 1 or 2 different problems. Cold Solder joint on Mobo. Bad DC Power Jack. 1: if it is the Cold Solder, you can reflow the solder and be done with it. 2: if it is the DC power jack, It should be replaced. For simplicity lets call them DC(A) and DC(B) There are 3 connections to it. Gnd, DC (A), and DC (B). When the powersupply is plugged in, contacts (A) touch to send +DC to the laptop. (B) is open. When the laptop is using battery power, contacts (B) touch to send power from the battery through the system. Over a period of time (inserting and removing the DC Power Cord), the contacts become fatigued, or oxidized and the DC(B) never closes - so it won't work from DC Battery. RATE ME - if it helps

How will I know if my laptop Compaq Armada m700 is fully charged already?

Hi

You do not say which operating system you are using.

Right click on the toolbar at the bottom of the screen > properties > notification area > tick the Power under System Icons - Select Which Items to always show > Apply > OK > float the mouse on the battery icon to see % of charge and charge time remaining.

I hope this helps.

Battery for Compac Armada M700

Hello Felcen:

It could be just a coincidence...but lets try a few things...

Remove the battery and unplug from the wall. Hold the power button on...and then plug back into power...after 8 seconds release the power button. Once your computer boots to desktop...shut down...and replace the battery.

Changing the harddrive should have anything to do with teh battery...

See if your battery starts charging after this trick.

Let me know and good luck my friend.

Compaq Armada M700

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.
