    I'm on my second battery from Dell for my D430 PC notebook.
    The first would not hold a charge, so I got shipped another. It's been a month and now I have the same problem.

    I've used two different adapters to make sure it wasn't that.

    Is there a setting or two I can check?
    Thanks,
    Morgan Mandel

Start by replacing the power supply. That should cure it, if not, let me know, there is some other (more expensive) possibilities.

No power


OK, there are a few things to check.
1) does the power charger charge the battery? does your charging lights come on? Try and obtain a replacement charger to try (make sure yoiu use one that is rated for your laptop or you could damage the charger or your laptop. You can check the required ratings by looking at the sticker on your charger and using one with the same Volt/Amps rating.
2) try removing the battery and running the laptop just off the power supply - if this works, its likely your battery

If its none of the above, try to reset your power - remove the battery and the power supply then press and hold your power button for a minimum of 20 seconds. Reconnect the battery and charger and try again - if this works great, if not then the problem is likely to be mortherboard related. There are power regulators on the motherboard and its possible that these have blown. Take the laptop to an electronics engineer and get the fault addressed - expected repair cost would be about 50-75 GBP.

Hope this helps a little

Laptop screen flickering when battery charging


The power supply adapter may not be delivering enough power when you run it and trying to charge the battery at the same time. The only way to find out is sub another power supply.

Toshiba satellite l300 not charging, doesnt work on the power supply


Try removing the battery completely and running it with the power supply connected. If that doesn't work, try borrowing a compatible power supply, or buy a universal one, and try with and without the battery connected.
The problem may be the power supply, in which case the battery won't charge and the laptop won't get any power.

My dell studio 1737 will not charge the battery; however it will run on either the battery or the power supply at leas until the battery dies completely. The power supply is working properly. I have tested...


If the power supply is powering the system without the battery installed, and the battery powers the system without the power supply attached, but the power supply will not charge the battery in the system...chances are very high the charging circuit on the systemboard is not functional. There are a few possibilities as to why but the only real solution would be to replace the systemboard since the charging circuit is integrated. You could run through the charging circuit to locate the exact fault but you will need schematics in order to resolve if you are comfortable with micro-soldering.

To verify, if you can, place the AC adapter and battery into another 1737 and see if you get charging on the battery.

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.

Battery will not charge


Hi cdravi

Laptops have a power supply control section attached to, or part of the main board. This allows the laptop to switch charging on and off, and control power supply function to different areas of the machine. Sounds like you have a fault in this part of the computer. Off to Dell Service for that one I am afraid.

Not charging


Make sure you are using a 4.62A Power Supply (90watt) some of the knock-offs are only 65w (3.34 A). And you will never have enough current to charge the battery.

It will only run the laptop, but not charge.

The mobo sounds like it is good, if you had a power issue, you would have orange lights or blinking, and it would not come on at all with any power supply.

My PC won't run with ac /dc power!


Hello. There is a hardware failure with the laptop not the AC charger. AC chargers have some range of protections of their own. If the power requirements of the laptop are bigger then what the charger can handle, the charger will turn off. Also other parameters can bring the charger offline. In your case, you have a problem with a small chip, the battery charge controller unit, witch regulates the amount of current required to propperly charge the battery. When this thing fails, the charging requirements for the battery are reported rong and the AC charger is forced to give more power then necesary. This results in disconnection of the AC charger ( an internal fail safe of the AC charger) and the laptop to swich back to battery power. When the laptop is turned off, it can charge the battery because the power requirements are low, having all processor, main board, hard disk etc turned off. Therefore the AC charger can handle the load. However you will need to have it checked by a service center as it is a hardware fault. Both AC charger and laptop needs that check. The charge controll circuit needs to be replaced probably. It will be a somewhat expensive repair. Don't buy any other battery untill you have the laptop checked. For more aditional info please post back. PS. Sorry for my bad english, I am from Romania, it is pretty hard for me to explain tehnical stuff in english.
