ZV500 power plug problem

I had the power plug replaced, but the laptop still doesn't power up: the 3 second lighting bolt LED indicator thing, and then nothing. So now my options are either repair the system board, or replace it. I'd like to try to repair it myself, but I don't have a schematic. Do you have any suggestions? Thanks.

I've repaired alot of laptops... One thing that I found works the best is get 3 bowls or dishes.... Label them; 'Top', 'Bottom', and 'Logic'. Almost all laptops require you start disassembly at the base of the unit. Unscrew every single screw you see, make sure there are none left before you start on the top. The way alot of laptops are set up is that you unscrew the bottom, pop off the top casings/covers then unscrew the top screws. Once you've removed all the screws from the top and the bottom, there will be very little attaching the casings, so be careful. Remember to Unplug everything you see attached to the logic(mother) board, or you risk ripping a fixture off the board. Once you have freed the logic(mother) board from the attachments and casings you should very careful.

Now as you start work on the power jack, I Highly recommend you use a solder wick and flux to remove any solder left on the board from the previous repair. It is never a good idea to leave old solder on the board. You should be careful with the solder you don't want to short anything out by using to much solder. Once you have finished your repairs to the DC jack you should test it out plug it in to the AC Adapter and look for any visual indicators of life(i.e. charge batt light).... So now you know it works.

If you get it back together and it suddenly doesn't work its possible you have a case short. If thats the case look on the metal casing for any discolorations or blackness and if you find any place some electrical tape over it... it should be fine.

Good Luck. Don't be nervous its not as hard as it seems.

Hope this helps lemme know if you have any questions.

Presario R4000 battery is charging but the lightning bolt is not lit


When you first turn on the laptop, does the lightning bolt LED light up for a split second, even before Windows opens? That is a test that the LED is not burned out. If it does, then are you using the correct AC adapter that came with the laptop? Some look identical, but are not as powerful enough to run the computer correctly and you wouldn't necessarily notice a difference except something like the LED. How old it the battery and how long does it take to fully charge?
1. Reset the laptop by shutting down the laptop and unplugging from AC power;
2. Remove the battery;
3. With the computer unplugged and no battery, hold down the power button for 30 seconds. Remember no power on the computer at all for this step.
4. Replace the battery and plug it back in and turn on.

If that doesn't help, search the internet or HP's web site and update the BIOS for your specific system. Look for good directions for doing this and don't run the BIOS update from the internet, you should download the BIOS to your computer and then run it from there. The BIOS cannot be interrupted. If the BIOS is interrupted while installing, it WILL render your computer useless and you will have to replace the motherboard (extremely expensive).

The adapter stopped charging my laptop due to a faulty wire, I bought a new adapter and now as soon as I plug in it starts for a second and turns back off. The charging light blink and it doesn't


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My Notebook all of sudden doesn't power on.


I find that many times when a laptop won't power on either on batty or plugged in, the thing to try is to unplug it, then taske the battery out for about a minute and then put the battery back in and try again.

Dell inspiron 6000 dead when connect power adeptor to laptop the led light on psu goes off is this mother board fault or psu.


If the led on the power supply turns off after connecting it to your laptop, the problem most likely lies with the power supply especially if the machine will run on battery power. This can be tested by

1. Turn the laptop off.

2. Remove the battery and power supply plug.

3. Press and hold the power button for at least 15 seconds to reset the laptop.

4. Replace the power supply plug into the laptop without replacing the battery.

5. If the computer will not start and there are no lights turning on on the laptop the power supply is bad.

6. Replace the battery and attempt to start the machine both with and without the power supply plugged in.

Hi,

The middle blue led is the charging indicator, sounds like you have (at least) a bad battery, remove it, plug in AC and try again, if no good, remove the HD and repeat, if no good, remove/replace the ram and repeat, if still no good, your mainboard is cooked.

Thanks,

Adam.

I have a new e627 used only once before today. Battery connection was partially out and screen indicated low battery. After five minutes screen went black and now I cannot power up.


Maybe your battery is totally drained.

Try to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.

Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.

Put in a branbd new battery. Power adapter is OK.


Your motherboard does not need replacing provided the problem is the power socket on the motherboard.
If the power adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.
