Toshiba Satellite L655 will not power on

I have a toshiba satellite l655 that the power dongle was broken because the power cable got yanked out of the hole and it broke the plastic inside. The laptop ran until the battery ran down. I purchased a new cable and installed it but the laptop will not power on. I get no power light to signify it is plugged in or a battery charging light. Thinking that it was probably the motherboard got shorted during the whole ordeal, I purchased a new MB. I replaced the MB and still the same issue. I have tested the voltage all the way to the MB and it has a solid 19v all the way. I have tried to power it on with only the power adapter plugged in, I have pulled the cmos battery. I have tried the "hold the power button for 30 sec" trick. Everything logically should work but it is just unresponsive. Any ideas???

When the mobo was replaced were all the wires connected properly?, It is strange that you don't get at least a battery charge light, indicating that the battery is charging. I would start by unplugging the keyboard, removing the hard drive, optical drive, the wireless cards, modem and the battery. See if it will power on with out these items, if it does insert them back one at a time, trying to power on system after each item is being replaced until it no longer powers on then the last item could be shorting out your system. If it does not power on after all these items are removed remove the memory. then insert the power adapter and try to power it on see if you get any diag lights lighting up. Always always when removing and inserting components remove the power supply and the battery. You should also be wearing a grounding strap to ensure you are grounded against static discharge.

Yeah, I already tried all that. All that is hooked up is the power and battery. The only components are the CPU and one stick of RAM. if I remove all the RAM it still does not power on.

You tried powering on the system with the battery removed, and connected only via the ac adapter right? It could be faulty mobo even though it is new (this is known as Dead on Arival  [DOA]). or it may be a faulty power switch.... but then you should at least see the charging led when the battery is inserted.

web_tracker: Yes, I tried powering it up with the battery out. I'm beginning to think its DOA also. Just kind of strange that it ran for a while on the battery after the incident but then wouldn't power back on.

nobus: I already have replaced the power dongle. Its not just a jack in this model, it actually is a cable that plugs into the MOBO.

If you ran the battery down until it was completely dead, it may have problems recharging.  However, if you removed the battery, the laptop should still work if plugged in to the AC charger.  Perhaps the AC charger was damaged during the incident and can't provide enough current?

Tested the charger. Solid 19v output.

did you test it under load?  if not it can still be bad
you can test the AC adapter on another laptop, or test with another one on yours

Nobus: Amazing. I have never seen a power adapter that would give a steady precise voltage but die under a load. I tried a different p/a and it booted right up. Even with the old MB! Super job full answer credit!!!

Ha! - I was the first to say that the adapter was probably damaged and couldn't provide enough current.
