Notebook 按 power on 無反應, 完全唔郁, 但 power supply 和 adapter 都正常, 點算?

Remove your battery from your notebook, then connect power adaptor to your notebook. Turn it on, then install your battery back into your notebook while the power is on, that's it.

The problem is that your power regulator chip inside your battery is malfunctioning, by doing the above procedure will reset it.

Easy huh?

Thanks brother.
However, my battery already damage previously, and I didn't use it quite a long time.
Any other suggestion?
What is the cost send for repairing?

Hello again,

Please note that the way notebook batteries supply power works the same as an ATX power supply for desktop computers.  That means your notebook won't receive the correct amount of currents needed to function with a defective battery, therefore i suggest that you take your notebook to a repair shop and let them test it with a new battery.

If you only had it for a shot period of time, then your battery should still be under warranty and you should have it replaced as soon as possible without having to pay for a new one.  The cost for a new battery well, varies and should be under $150 US.

The battery acts as a bridge between your power adaptor and your notebook, when that bridge is broken, you have no power or incorrect power to your notebook so its common mistake for people to think that when the notebook is supplied with power from the adaptor the battery will 'bypass' the current.  That's not entirely true because the battery will somehow 'take control' or regulate da currents going into your notebook when its installed.

Hope this helps, good luck.

Bro.armageddon, sorry to interrupt you as I have a question on this topic too.

I had bought a NEC notebook in 2004. I find that it can be run without battery (directly connect to AC power) Would you mind to tell me the reason why it can work? Is there any problem if it be run in this way?

Thanks in advance

Well like i said before, the battery will 'take control' of the power (current) going into your notebook when it’s installed. Think of it as a regulator switch, when the switch is off (without battery) your notebook is receiving power directly from the adaptor. Part of the power is routed to the battery (Charging Cycle) when its installed, but an imbalanced input of voltage from a defective battery (Power = Voltage times Current, or P = VI) means the power received from the adaptor has to either increase or decrease depends on how much power the battery is sending to your notebook mainboard. Both the notebook and the battery have built in power regulator acting as a fuse in case of imbalanced power input, that's why you can't turn it on when you had a defective battery installed.

The households lighting system works the same way but without a regulator. I don't suppose you will cut off the power supplying to your house by removing a bulb from your lamp, right?

Thanks brother, but do you mean that I need to put on the battery whenever I used the notebook. I used the notebook for more than 3 years, and I didn't take out the battery until one day I found the battery is damaged (I wonder it is over-charged), then I released the battery from the notebook, but the notebook still can work for nearly half year.
I always think the battery is only used when you cannot connect the notebook to the Main Supply.

Bro.armageddon, thanks for your professional tutorial!!!
高手!!!

Hello again,

Not really my friend, when the battery is defective do not install it back into your notebook because it could further damage both the adaptor and the main board. Although its a good idea to remove your battery whenever there is AC power supply to prolong battery life, it will also worn the connectors faster in da battery holding bay. The average life for a notebook battery (Li-Ion battery has about 300 to 500 charged/discharged cycles) is about 2 years, so even if its not damaged and after 3 years i don't think it can supply power to your notebook for more than 30 minutes after its fully charged.

If you can't turn it on without a battery, and no response whatsoever when you try to turn it on, send it to a repair shop because there is nothing you can do to fix it at this point. Ask the technician from the repair shop to try it with a new battery first, then check the power switch to see if the button is worn. Please also ask them to remove all the attachable devices such as CD-ROM drive, floppy drive and the hard drive, then double check the AC adaptor connector and try again. If all checked out ok and still no luck then my friend, you might want to reconsider getting a new unit because at this point, its not worth it to spend money to get it fixed.

Good luck

Oh sorry i forgot something, also ask them to try with a new memory module as well. A defective memory module can also cause problems to the power supply system. I am thinking about trying a new CPU but hey, you expecting them to order a new CPU for a $200 US dollar labour job?
