Compaq M2000 turns on using charged laptop battery but doesn't charge or turn on when using power adaptor, with or without the laptop battery


1) The AC adapter should ALWAYS be plugged into the laptop FIRST, then plugged into AC power. If not, this could create a voltage spike.

2) Let's look at the DC Power Jack, for the Compaq Presario M2000 series of Notebook PC's,

http://www.notebookparts.com/products/description.php?II=9741

The DC Power Jack is mounted to a removable circuit board.
Enlarging the view of the jack, shows us there is an Inductor.

The small 'can' standing up on the power board. This chipset could have gone south. (Bad)

How to know? Replace it, or dig out your dual trace oscilloscope. See if the Inductor works.

Could also just be cracked solder joints, of the DC Power Jack, TO that small circuit board. Solution would be to resolder it/them.

[ I WOULD however, search for a BETTER price, than listed in the link above, IF available ]

DC Power Jack is in good shape, soldered tight to the motherboard, and ruled out as the problem?
(Since you know the AC adapter is good)

Then the problem would be the Inductor on that power board, or power correcting chipset.

What one is it? Dunno.
DO KNOW is has J leads on the bottom.
CAN give examples, and perhaps you can identify using them.

I have compaq presario f572 notebook laptop. when i plug in AC adapter charging light is turn on but when i press power button its not turn on. anybody can help me............


The laptop is probably charging the battery. I assume you have already tried running this on AC power alone with the battery removed and then on battery power alone? If not try those methods first

Check to hear if the CPU cooling fan is spinning and there are sounds of the hard drive or CD Rom baing accessed. The laptop base should get warm around the heatsink vents after a few minutes too.

If there is CPU and HDD activity, the problem is most likely related to the graphics chip, common on HP / Compaq laptops. This will need a Reball.

If the laptop will physically not turn on and there is no activity as described above, the first thing to look at is the power switch. Remove the switch bezel and see if the power button on the motherboard is sticking or damaged (small contact about the size of a matchhead). Also check if there is a small cutout switch just below the screen near the hinge that is sticking or damaged.

After that, the issue may be the power circuit. Check that the AC adaptor is a tight fit and dis not sloppy, it may still charge the battery but fail to provide power for booting, it will need replaced if sloppy or loose

After that, the issue is likely to be motherboard related and will need a technician to test fully

Compaq Presario A900 won't turn on, and battery won't charge (no blue light on when battery charger cord is plugged in.) Any ideas please? Thanks.


The power connector for these Compaqs are notorious for failing when they get a bit grimy. Try wiggling the connector or cleaning it or even gently squeezing with pliers.

Remove the battery and plug laptop power into the wall (or power strip).
Turn ON laptop without battery.
It should start.
After Windows has settled, put battery back in and let it charge up.

Hope this helps!

Compaq presario notebook v6128tu won't turn on


You can try to remove that battery and try to turn it on again.
Sometimes this will happen if that don't work the remove the power supply and try to turn it on.
If you see the blue light around the power input then it's obviously getting power but it's redirecting it somehow which brings us to the battery again heh.
Let me know if this does not work
Happy Holidays
