Question about Toshiba Tecra M2-S530 Notebook
I have a Toshiba Tecra M2 that will not boot up. I could get it to boot a few extra times by removing the main memory chip under the keyboard and reinstalling. This is no longer working. Plug it in-AC power and battery LED light in front. Power light comes on the front when you push the power button.Push and hold the power button again, and power light goes out. This is all it does, no display, no fan, not HD start up. After awhile the AC power LED goes from straight green, to blinking amber. Tried removing the battery and trying to boot-no help. Tried different processor-no help. Tried different RAM chip-no help. Tried external monitor-nothing. Tried different power supply-no help. Leaning toward motherboard, and if so, looking for advice as to where on the motherboard. Thanks
I have seen a lot of Toshiba Laptops with bad "DC Connectors" on the motherboard. It sounds like you know what your doing so here a link on how to disassemble your laptop.http://www.irisvista.com/tech/laptops/ToshibaM2/tecra_M2_disassembly_1.htm

This is motherboard hardware issue
1) first all you need take out all devices like HDD DVD, wireless card then try turn it on if noting yet
2) change RAM stick that you have done
3) check DC PWM standby status, like 3V/5V/1.8V which should be appear before power on.
if no 3V/5V DC output, check this PWM circuite like MOSFET or PWM chip.
if you find 3V/5V, so need check 1.8V DC output and 1.2V that chip fail also cause nothing turn on.
all steps need diagram check where the chips and componenets on your board.
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question
