My gateway laptop note book, will not power up, I have checked the cord, battery etc. Went to turn it on one day and no power? someone mentioned that it over heated?


First of all, take the battery off and try to turn it on with the ac adapter (power cord) connected. If it comes up without the battery then it's your battery.

If it doesn't turn on without the battery and with just the ac adapter, try a different ac adapter. You can find one to try at your local pc shop or electronics store. If it comes up with another ac adapter then all you need to do is purchase an ac adapter at the store or order one online (cheaper).

If it still doesn't come on then it's either your dc jack or your motherboard. Normally if it's just the dc jack it will turn on or attempt to turn on when you wiggle the connecter in the ac adapter connection. If it's your dc jack it's relatively inexpensive to purchase online. The problem comes with having to take apart the laptop, desoldering the old and soldering the new dc jack, and putting the computer back together.

Good luck and let me know if you have any other questions.

Laptop wont come on


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced

My loptop is an Averatec 7100. How can I test the motherboard? I took it to a computer repair shop and they said is the motherboard, I want to know how can I test it on my own.


This is more of a system diagnosis that an actual motherboard testing procedure, but since all components attach to the motherboard in one way or another it could count as a prcess of elimination......

Laptop is dead. How to troubleshoot the problem.
In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.

What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.

OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.

If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.
First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint.
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.

In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Finally, disassemble the laptop and removed the motherboard.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch you need to turn on the system.
5. Working DC power adapter.

Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

Dead Toshiba A100 laptop computer


In order to replace the power jack in your laptop you’ll have to remove the jack from the motherboard as I explained in the previous post: Replacing DC power jack.
While removing the jack you can accidentally pull out the internal copper coating (I’ll call it a sleeve) from the inside of the “+” terminal as it shown on the picture below.
9807c6d.jpg
The internal copper sleeve has been removed and cannot be installed back. If you solder the power jack back on the motherboard without this sleeve it might work but the connection between the “+” lead and motherboard will not be reliable.
In the following guide I explain how to fortify a damaged power jack connection. You can use this repair technique in some laptops with similar power jacks.

Hp pavilion dv6000 not charging when pluged in


Hi,

Common causes of similar problems are a loose connection or a cold solder on the DC jack at the end of the laptop. In some instances, it could be the actual charger/AC adapter that may be at fault. This however could be verified with the use of a voltmeter measuring the DC voltage at the output plug. As to the DC jack, it would be more of a concern opening the laptop and exposing the underneath of the motherboard (where the solder are) rather than the actual repair which is soldering. Incidentally, there are cases where the terminals/pins of the DC jack might have been cut off hence a replacement may be required. Perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Need to repair laptop power supply port, very loose and laptop will not come on.


Hey, its kinda tricky if you aint done it before, go onto google and search for your laptop model dc jack, they usually cost about £5 including postage, then you need to dismantle the entire laptop, remembering where each part goes back into, once you get the motherboard removed you need to unsoldier the old dc jack, and put in new one and resoldier it.
will take you about 1-2hrs in total, or should cost you about £55 for a shop to do it.

we do alot of them, but if you aint done this before it can be very tricky..

Hope this helps
