Question about Toshiba Satellite M30 Notebook
Troubleshooting some problems with a laptop.
This system does NOT have the following issues:
-ac power jack malfunction
-chassis/shielding short circuits
-display problems, LCD connectivity or anything related
-The computer simply shuts itself off after being moved just slightly, or it eventually powers itself off when use after 5 to 10 minutes of normal use.
-most likely something wrong with the motherboard
What i have attempted so far:
-Laying the laptop on its screen side has been the only way to get the laptop working continuously without powering itself off. I was able to have this computer running steadily for 3 hours while it was layed in this awkward position.
- this computer only runs properly in a certain position or it will not boot, sometimes slightly bending the mainboard upwards solves this, or putting something beneath the mainboard to apply just little pressure upwards (i used cardboard) has helped. I did my best not to put too much strain on the solder joints or traces which may cause a mircro-crack.
My theory & question:
1 The issue i believe is due to something wrong with the motherboard and is electrical in nature. Something has a poor electrical connection, a trace is damaged, or a component has a cold joint. How should i pinpoint the part of the mainboard that needs soldering? Which is the most likely component that has failed? I have taken a good look at this mainboard through a microscopic lense in an electronics lab, and i found nothing.
Probabily you a malfuntion on some cable connection. Remove everyone then plug into place again.
That should fix it.
If don't you have a connection malfuntion on you motherboard, processor or memory, try memtest.org to download the memtest program and test all memory.

This seems like memory issue. Have you tried to replace the memory? Static electricity can cause this sort of errors. If you take out the battery, unplug it from power source completely and take out the memory and put it back, it might help, if it is caused by static electricity. Otherwise try to put it in different memory slot.

You may have a loose DC jack:
Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.
If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it's still under warranty, it would be fixed at no charge to you.
