It is quit possibly thermal shut down... is the bottom of the laptop extremely hot ?

Robert

The solution is to remove as much of the case to give you access to the fan(s) and clean all the dust and dirt out

Cf51 wITH MOTHERBOARD dl3up1448aaa. When connected to the power supply smoke was seen coming form the power socket on the laptop. Disassembled the laptop and found just behind the socket on the motherboard...


Hi,


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

My acer aspire 6530 suddenly stopped charging the battery, it works with battery, works with battery and main power supply (yet, as long as the battery is still charged), and it certainly doesn't work with...


Seems like this is the case of a bad power supply adapter, and needs to be replaced. But to make sure we are on the right track, you mention towards the last statement, you said that when your laptop is off, and the battery is installed on, and without the power supply, the computer power button would flash and no sign of life right? Well take these step to see if it is the power supply, 1, check to see if the small green light is lighting from the powersupply adapter. If it is not, then 100% you have a bad power supply. 2, does the laptop power on when using the power adapter only, and with the battery pulled out? If not, then 85% still is your power supply and the other 15% is your power jack, either is loose, or bent, as we tend to plug in and out alot. 3, Does the laptop power on with the battery itself without the power supply adapter? If it does, it is not your battery. The reason to the laptop power light blinking with the battery installed only could be that the battery is low/drain and does not have issufiect charge to power up your laptop. And to say that when your system is on and your plug in the powersupply, and the small battery icon says it's charging but actually it is not. It could still be your powersupply, it is damaged but a smart chip installed on your powersupply only sending signal to your laptop, this chip is only to prevent the battery from over charging. So if you have another power supply, you cna test this out. But at this point, they was you described things, I believe it to be the power supply. I hope this help, if you have any question, let me know.

My daughters power supply for her C640 has a pinch


I suggest you DONT USE PINCH POWER CORD FOR SAFETY.

PLEASE TELL ME IS YOUR POWER CORD & THE PINCHED CORD ARE SAME? I MEAN SAME MODEL? AFTER PLUGING OF YOUR CORD, THE BATTERY CHARGING LIGHTS ITS ON? IF NO THEN I GUESS THAT CABLE NOT SUPPORT HER LAPTOP.
VISIT A DELL SERVICE CENTER OR A SHOWROOM AND BUY NEW CORD WHICH IS MADE FOR YOUR DAUGHTER LAPTOP MODEL.
OTHER WISE SOME CHANCES OF SHORTCIRCUIT ON MOTHERBOARD.

Thanks, i am waiting for your feed back & if you satisfied then thumps me please.

The power button doesnt seem to be working


It sounds like a short in the button itself. If you have a soldering gun, take it apart and resolder the connection. This is typical for Acer laptops.
It's either the button itself or the jack where the power supply plugs in. It's not real difficult.

Possible blown motherboard


you need a fully working battery as while you plug power adapter power light does not come on nor does the laptop itself turn on please check the power supply and its cord . If you have have not grounded the power supply third terminal this is possible that power is coming from body of your laptop.But check DC voltage output of power adapter. It should be approximately18 to 20 volts

Keeping the power on


I have seen that problem before, but on a desktop. I guess you have tried all the connectors available in your house. Hmmm! It think, not sure, but pretty sure, it is the motherboard the problem.

My laptop turns on and then it turns right off!!! HELP!


hi there
It seems your laptop computer is not cooled properly which might be beacuse of a broken cpu fan as you mentioned it makes loud noise.
The reason your laptop turns off by itself is because theres a circuitry built on the motherboard which power offs itself if the internal temperature raises, this is a safety feature to prevent your computer getting burnt.
Please avoid using your computer and take it to a shop where you can have it checked for cooling.
hope this answers your question

Turns Off by itself


Causes for this problem can be any of the following:
1- CPU gets overheated. solution: clean dust from fan and heatsink assembly and donot forget to replace the heatsink compound, this is very important.
2- Memory problems. solution: use a program called MEMTEST86+ from the site http://www.memtest.org/ . It is a free and great program.
3-Power problem. By time the capacitors of the power supply gets dried. Causing them to not be able to fulfill power demands. solution: try working with power supply without battery. As the power supply has to run computer and charge battery. We reduce the load. If everything is fine. repair power supply by replacing deffective capacitor.
4-Battery problem. Try operation without battery.
5-Dried solders on motherboard or a component problem on the motherboard. Solution: no solution except replacing motherboard.
