    I have a Dell Inspiron 9300. It has a brand new battery (9cell .. good quality). The charger checks out ok. So it must be the mobo. Is there any way to fix this or is it just a case of bad mobo/bad laptop?

Go into the battery properties and check if the battery is charging. If it says it is, then test it, use the battery to see if it really is charging, they will sometimes give a false reading. If it's not charging, then check the power supply with an ohm meter for the proper output. If this all checks good, but the battery isn't charging, then I'm afraid you have a failed power management system on the motherboard. The power management system controls the charging along with other power related aspects of the machine. If the power management system has failed, then unfortunately, you will have to replace the motherboard in order to fix it.

The battery is most likely defective. Dell batteries and computers have a history of failure though, so I wouldn't be shocked if you find some serious problem with your computer

Green light is blinking while charging


On page 2 of the manual it says:
Battery charging light. Blinking : Charging
Lit: finished charging.
So everything is still fine. At least as soon as the light burns normal.

My Gateway M-6847 will not turn on. When I press the power button the wireless light and power button light just flashes quickly. Also the battery light in front stays lit while plugged in.


Hi

My laptop won't power up. I have removed the battery and tried starting it, nothing. I removed the AC source and tried with only the battery and nothing. I noticed the led is a little dimmer than normal...


I know this sounds simple but have you checked the power connections at the brick (middle of the power cord) often this comes loose and is not noticed until battery is dead. The leds staying dim is what made me think of this. They will go out when on battery only especially if power cord is not producing any power. When you plug in the laptop do you see a little battery charging light come on?

I put a new black printer cartridge in and now it doesn't power up at all. I replaced the printer cartridge with the old printer cartridge and it still isn't powering up. I replaced the power cord,...


With the green light lit on the power box or power supply of the printer, that indicates that there is power flowing. But just to make sure it's getting enough to power the printer on, bypass any power strips or extensions, if you're using one, and plug the power cord straight to a known working power outlet. Make sure the power box or the power supply is inserted all the way in the slot and in the correct position behind the printer. Press the power button if needed. Hope this helps. If it's still not powering on, I suggest you contact Lexmark Technical Support for further assistance.

There are 4 reasons why your unit is behaving this way:
1. Charger is the problem.
2. The docking station is the broken.
3. The battery is broken or not accepting charge.
4. The actual unit is the problem.
It is very hard to tell which one is causing this to happen.
Let us do some troubleshooting first:
1. Plug your charger in an A/C outlet and make sure the red power light (left) is lit, otherwise the charger or the docking station is broken.
2. You can test the charger with a multimeter. Unplug the charger from the docking station and measure the voltage across the outside and inside, it should register more than 5 volts DC. If there is a 5Volt DC the docking station is the problem otherwise the charger is broken.
3. If the red power light is lit and the status light (right) is lit too, your docking station is broken.
4. If the red power light is lit, dock the unit into the charger, the status light (left) should turn red when your battery is accepting charge or turn blue when your battery is fully charged.
5. If the status light will not lit at all (while the red power light is on), tap the screen while the unit is docked on the charger. If the unit will become alive, you need a new battery otherwise you need a new unit.

12 hours is very long time to charge, the status light should turn to blue in less than 2 hours especially for a new battery.
