Pressing ON button gave case lights but no activity. When plugged-in, power jack could rock up and down but not side to side. Preliminary tests showed correct voltage from AC power adapter. Toshiba M35X-S149 Notebook - Customer brought this notebook into my repair shop with typical complaint that the system stopped running.

Related post: How to troubleshoot dead laptops. HereвЂ™s my previous post witch covers troubleshooting bad images on the screen in more details. It could indicate a problem with the laptop LCD screen, video cable, graphics card or motherboard. The laptop starts normally but video on the screen has lines, some strange characters or other defects Run the memory test and if it fails, replace the faulty module.

The laptop still boots ans you still can see the screen, so you can run the memory test. Listen for the cooling fan, make sure it works.ДЄlso this problem might appear because of a faulty memory module, try some tips from the situation 2. You restart the laptop but the same problem appears again

The laptop boots into Windows ans works for a while, but after that it shuts down by itself without any reason or warning. I usually use HitachiвЂ™s drive fitness test. If the laptop makes clicking or grinding noises and you still have video on the screen, you can run a hard drive test utility. If the noise is gone, the hard drive is your problem. You can remove the hard drive and start the laptop without it. Most likely you hear this noise because of a faulty hard drive. You start the laptop and it starts making repetitive clicking noise or grinding noise. Go to my previous post witch covers laptop video problems in more details. 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.

In this situation test the laptop with an external monitor. It sounds like the laptop is booting normally (hard drive LED is flashing) but there is no video on the screen Most likely you are getting a beep error because of a faulty memory. Try installing a known good memory module. In this situation test the memory module as I described in the situation2.

When you press on the power button, the laptop makes a series or short and long beeps and will not start up. If the laptop starts fine with both memory modules when they are installed in the slot A, but will not start with both memory modules installed in the slot B, the slot B is faulty and youвЂ™ll have to replace the motherboard or use only one memory slot. If the laptop starts fine with one memory module in both slots, but will not start with the second memory module in both slots, the second memory module is faulty. If you have two memory modules installed, try removing them one by one and start the laptop just with one memory module installed. Try installing the memory module into the other slot (if itвЂ™s available).

Try reseating the memory module, just remove it from the slot on the motherboard and install it back. It also could be a memory related problem. After that plug the AC adapter ans try starting the laptop again. Unplug the AC adapter, remove the battery and wait for 1-2 minutes. 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.ДЄlso try this. If the power LED lights up it indicates that the laptop is getting power from the AC adapter. There is no video on LCD or external monitor. When you press on the power button the laptop powers up but will not start. When you plug the AC adapter the power LED and the battery charge LED light up. The output amperage has to be the same as on the original adapter or higher, but not lower. The output voltage must be exactly the same as on the original adapter. If you have to replace the AC adapter, make sure you use a correct one. 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. It is possible the laptop appears to be dead because the AC adapter is bad (and the battery is discharged). If you cannot do that, find a known good AC adapter and use it for testing the laptop. You can test the output voltage with a voltmeter. You plug the AC adapter but the LEDs (power light, hard drive light, battery charge light, etcвЂ¦) do not light up and the laptop will not react at all if you press on the power button.ДЇirst of all in this situation check the AC adapter.
