SOURCE: Compaq Presario 700 won't power on

These are prone to broken power jacks that short out components on the mainboard. My shop saaw a lot of these come in dead like this and sometimes we could get them going again with a lot of mainboard work, but it seems they keep breaking.

I would save your money for another laptop considering the lousy reliability record these models have.

SOURCE: dell inspiron 5150 do not come on when the power button pressed

If you remove the battery and disconnect power cord, then hold power button for 20 seconds, then reconnect power cord but do not re-insert battery, and the unit powers on okay, the problem may be your battery. If there is still an intermittent problem, the power connector inside the unit may be loose and need re-soldering, or you could have a bad power supply.

SOURCE: C500 Laptop won't come on power button just flashes

Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

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.

My hp compaq presario v2000 isn't charging.:/ and it's not turning on. What's wrong with it? How can I get it to start working again? The last time I was using it, it turned off on me and it hasn't turned...


It is quite difficult to just get a failed laptop to respond as the faults can be many . So start with the power adaptor check the voltage, the voltage of the battery , if both are fine the laptop must power up . Now if bad replace or repair the adapter for smps failure in adapter check my tips :.http://www.fixya.com/support/r5826301-working_switch_mode_power_supplies

If the sett does not respond check the bios battery at the rear side , check the memory card for failure, might need to swap one.
If not there are errors inthe motherboard.

Receiving Charge will not turn on


Take out the battery and only have the ac adaptor hooked up to the laptop and then try to turn it on.

If that doesn't work, then the motherboard is faulty. Probably a short in the motherboard but the whole thing would need to be replaced.

Also make sure your using the correct adaptor as well.

COMPAQ V2000 WILL NOT POWER UP WITH DC/ADAPTER OR BATTERY


Hve u tried a differnt adaptor , the adaptor might be blown too ,try replacing the adaptor , also check for the power cord if it has any kinks in it which may be interrupting the power supply , since the adaptor 18.5 v 3.5 a is the most common of all hp adaptors u should find one to try .

Battery not charging...but is recognized by V2000


My guess since the battery checked fine in another laptop would indeed be the charging board or charging circuit on the motherboard.

Battery doesn't charge


Is that the original power cord for that? Or was that one bought aftermarket, some aftermarket chargers will only power your laptop and not charge.

No power


Do you know if the other battery you tried had any charge in it?
If the battery was charged then it will not be a power jack or adaptor problem. As far as changing power jacks it is not for the faint of heart. I have done several with success on them all but it is not easy. If you are comfortable with opening the laptop go ahead and check all the connections on the inside. Sounds like a motherboard problem
