Your motherboard has no power, or the computer itself.. or what do you mean here? The question indicates it is about a motherboard but something tells me that is not the case.

Please let me know, what make / model device are you referring to that has no power but the adapter is ok?

Please just reply to my answer here and I will get right back with you.

Thanks
Tim

    It sounds like the power module for this laptop, where the AC adapter plugs in, has failed... it is not distributing the power correctly. You have tested the motherboard connection, is that correct? It sounds like either the board itself has issues, or just the power distributor internally. Either way it is a very difficult repair.

    Please let me know, what do you think you want to do here? Are you going to try and re-solder parts on the board?

    To be able to tell over text based help without seeing it is nearly impossible. But it is something definitely bad in the power chain...

Hello

Since your laptops mainboard doesn't power on at all, and I assume this also includes that there are no lights that come on the machine, leds etc. it would indicate that either the AC plug is not connected properly, the socket is loose from the mainboard and might need to be soldered back on.

Or then the mainboard is faulty.

What do you expect in being able to repair a mainboard? this is a extremely complex board that is build by a number of machines in a factory, it consists of around 4 to 8 layers of traces.

Troubleshooting a mainboard will be extremely difficult if not impossible without proper equipment which you most likely don't have.

To solve the problem replace the faulty motherboard.

Plugged in and not charging


1) Use a multimeter, check the AC adapter (Charger) for power.
Make sure it is putting out the required voltage.

Have an assistant gently wiggle the cable FROM AC adapter TO laptop. See if there is an intermittent reading on the multimeter.

Have an assistant gently wiggle the power cord.

An intermittent reading on the multimeter indicates a broken wire.
Power cord is bad? Replace cord.
Cable from AC adapter to laptop is bad? Replace AC adapter.

If you have posted the laptop manufacturer NAME and MODEL NUMBER, I could have given you more than generic information.

Model Number is in the Bottom of the laptop. Post back in a Comment.

AC adapter works OK?

Check the DC Power Jack.
The DC Power Jack is the jack on the laptop, that the AC adapter plugs into.

DC Power Jack checks OK, this is your problem,

The battery cannot charge after connecting to a power source


Take out of your battery, then plug in your ac adapter, see if it works, if no, then you have a faulty ac adapter, you need to replace it; and if yes, then you adapter is ok, the battery or dc jack may be broken.

Unit will not come on-power ok ac to dc adapter ok


Great job on checking the power from AC to DC adapter. Also, make sure to plug the printer straight to the power outlet in the wall, bypass any surge device or power strip. Unplug and replug the power adapter in the printer, make sure it's properly secured and in the right position in the slot. Press the power button if needed. If this doesn't help at all, I strongly suggest you contact Lexmark Technical Support to further investigate the problem. I hope I can assist you more on this matter.

My Toshiba L10 will not switch on the power supply is ok and plugged in and there is a blue light on to say power cord is connected but still will not power up, any ideas?


Do you have a known good ac adapter to try it with? Or is that ac adapter you were saying lights on powering on a different computer?Try to test both to check the functionality of the ac adapter and the port. If ac adapter will work with a different pc, then possibly the port is damaged. You may need to replace the motherboard. If still it wont turn on, then you may just need to replace the ac adapter.

My dell inspiron 1525 wont switch on, no lights or sound at all please help!


The first thing to try is a different AC adapter. About half of all no power failures are the AC adapter no longer sends power to the system. You can also use a multimeter to check the DC output of the adapter (About 20VDC) If the AC adapter is putting out power or a known good adapter doesn't make any difference, then try reseating the LCD hinge cover cable connection. If still no power and especially if the power jack seems to be damaged, then a motherboard replacement or adapter jack replacement is required (Roughly $100 either way)

The computer does not seem to be charging up


Hi,
I am a Dell Certified System Engineer(DCSE)

try taking out tthe battery and then try powering the system only on ac adapter connected
if it doesn't power on only on the ac adapter make sure that the port on the system where you plug in the ac adapter for any kind of bent or broken pins
if the port is ok then get your ac adapter replaced.
