No Power


Your laptop's power jack may be broken, which is why your laptop doesn't charge your battery at all, which is why it won't turn on now. I would take a look to make sure that the power supply is good, the battery is good, and then see if the power LED is even coming on when you plug the laptop to a power source.

> Since power ws restored, I hav a low battery alarm for about 3 days.
The charge circuit probably only supplies a tiny charge current to prevent overcharging of the main battery and I suspect the original is a NiCad and has likely lost a cell or two (shorted; it's common with them) over that fairly long period.
Replacing it with either Lithium Ion or NiMh rechargeables with a honest voltage rating (*some aren't) is a good move; neither of these are as prone to failure as NiCad is. Don't be surprised if you still have a 'low battery' alert for several days since these batteries rarely have a full charge when shipped.
*So-called '9V' block batteries are, except for rare batteries, actually 8.4 or even only 7.2 volts. I have some instruments that indicate 'Low battery' with either of these even when fully charged.

Camera indicates low battery even for fully charged battery.


I have connected my PowerShot A2000IS that was doing the same thing for me and I discovered the following:
1) The unit works fine even down to 2.5V providing the supply source (i.e. batteries can deliver 500 mA for a short burst during startup, i.e. when the camera's lens is extended). The camera draws 300mA with screen on after the initial startup current has settled. This means that the camera may not work with batteries like normal alkaline as these don't normally supply large currents, like NI-MH and NI-Cd can.
2) I found that if I lowered the voltage down to (using my bench power supply) that the low power indicator come on at just under 2.5 Vs, BUT once it has indicated low battery, turning the voltage back up to 3V didn't remove the low battery indication.
3) Finally I connected my fully charged (with combined voltage of 2.7V) Ni-Mh rechargeables (old and well used) using wires to allow me to measure their voltage and I found that when I turned on the camera the voltage dipped to 2.3V, but come up after the lens was deployed.

Conclusion and recommendations:
a) Get some new high quality Ni-Mh cells.
b) Don't use Alkaline cells (even Duracell brand might not handle it).
c) Forget Ni-Cd as terminal voltage would be at best 2.6V which doesn

I have desktop computer with mercury & there is no display on monitor even no boot screen in coming up. I have removed the battery & RAM and reinstalled it but problem is not solved.


When you connect the AC power, does the fan on top of the CPU move, or even just "twitch" once?

When you press the ON/OFF button, does the fan spin?

If not, then your power-supply is the culprit. Replace it.
Or, take the computer to a computer-store, and have them
temporarily connect a different power-supply, to trouble-shoot.
If you buy a new power-supply from them, they might even install it for FREE, if you ask.

Laptop is plugged in. Notice on screen that battery was low, even with it plugged in, and now no power lights on. Adapter light is still on indicating outside power supply on. Removed and reinserted...


The batteries do go bad overtime and will no longer hold a charge but the laptop should still work as long as the power cord is connected. If it still does not work with the power cord connected then it is most likely the power cord, these can go bad, but make sure that the power is securely connected and that if it is plugged into a power strip that it has not been turned off, try another outlet just to rule it out as well.

Power issues on HP DV1000


It is possible you have two dud batteries. Recharageable batteries have a limited life, they have a finite number of charge and discharge cycles.
With the battery removed and only the power supply connected and the laptop powered up, when you touch the connector on the laptop and the laptop does not shut down then the laptop connector is OK.

If you can verify your new battery is OK the the fault could be the power supply adapter, if may not produce enought current to run and charge the battery. Try charging the battery overnight by turning off the laptop and leaving on the mains t charge. Borrow a mains adapter and test it on your computer.

You can also check the BIOS setting for power management, ie. hibernate, low power shut down etc.

Do you have a different power brick to use? Sounds like the brick output no longer supplies the required voltage/amperage.

What is the DCV power output and Amperage of the brick?
and what is the Part number of the brick
