No LED light, no sound, etc. Tried another adaptor but still no response. I think you are right. Sounds like a problem with the motherboard. Also, there is a chance that the motherboard itself is OK but you have a problem with the power jack.
Here are some troubleshooting tips for you. The laptop appears to be dead. You plug the AC adapter but the LEDs power light, hard drive light, battery charge light, etc… do not light x700 and the laptop will not react at all if you press on the power button.
First of all in this situation check the AC adapter. You can test comaq output voltage with a voltmeter. If you cannot do that, find a known good AC adapter and use it for testing the laptop.
It is possible the laptop appears to be dead because the AC adapter is bad and the battery is discharged. If you know that the AC adapter is working properly and it outputs correct voltage but the laptop is still dead, most likely you have a power issue on the motherboard or power board on some laptops and it has to be replaced. If you have to replace the AC adapter, make sure you use a correct one. The output voltage must be exactly the same as on the original adapter. The output amperage has to be the same as on the original utrn or higher, but not lower.
When you press on the power button the laptop powers up but will not start. There is no video on LCD or external monitor. Most likely there is nothing wrong with the adapter but just in case test it with a voltmeter to make sure the output voltage is correct.
Also try this. Unplug the AC adapter, remove the battery and wait for minutes. After that plug the AC adapter ans try starting the laptop again.
Sometimes this trick helps. It also could be a memory related problem. Try reseating the memory module, just remove it from the slot on the motherboard and install it back.
If you have two memory modules installed, try removing them one by one and start the laptop just with one memory module installed. If the laptop starts fine with one memory module in both copmaq, but will not presqrio with the second memory trn in both slots, the second memory module is faulty. Replace the module. When you press on the power v700, the laptop makes a series or prresario and long beeps and will not start up.
There preesario no video on the screen. In this situation presaruo the memory module as I described in the situation2. Try installing a known good memory module. Most likely you are getting a beep error because of a faulty memory. You start the laptop. It sounds like the laptop is booting normally hard drive LED is flashing but there is no video on the screen. In this situation test the laptop with an external monitor. If the external screen works fine but there is no video on the laptop LCD, most likely there is a problem inside the laptop display assembly.
Onn to tugn previous post witch covers laptop video problems in more details. Most likely you hear this noise because of a faulty hard drive. You can remove the hard drive and start the laptop without it.
If the noise is gone, the hard drive is your problem. Replace it. If the laptop makes clicking or tudn noises and you still have comapq on the screen, you can run a hard drive test utility. This test is reliable and easy to use. The laptop boots into Windows ans works for a while, but after that it shuts down by itself without any reason om warning.
You restart the laptop but the same problem appears again. Listen for the cooling fan, make sure it works. Also this ob might appear because of a faulty memory module, try some tips from the situation 2. The laptop still boots ans you still can see the screen, so you can run the memory tufn.
Run the memory test and if it fails, replace the faulty module. The laptop yow normally but video on the screen has lines, some strange characters or other defects. It turb indicate a problem with the laptop LCD screen, video cable, graphics card or motherboard. Related ptesario How to troubleshoot dead laptops.
