My wife has a Toshiba Techra 8000 that up until yesterday has performed like a champ. She powered it off yesterday morning to do some cleaning elsewhere in the house and later wanted to check her email, but it would not power on. I checked it out last evening and indeed, there is absolutely no response when you try to power on. When you plug in the AC adapter, the power-LED on the adapter glows steady green if you do NOT plug it into the laptop. The moment you plug the adapter into the laptop, the power adapter power-LED blinks green on-and-off-and-on-and-off, etc. Specifically, it blinks on, then fades off and then immediately back on, and repeats that for as long as the adapter is plugged into the wall outlet and the laptop. The moment you unplug the adapter from the laptop, the AC adapter's power-LED immediately glows steady green again (no blinking). This is 100% repeatable and I don't see a pattern, such as if a code is being displayed. It is just an on-and-off-and-on-and-off blinking "pattern." I tried removing and re-inserting the battery many times, unplugging/re-plugging adapter in the wall, trying to power up on just battery, and even removed everything connected to the unit such as her printer cable, wireless card, and the wireless-mouse transceiver. I also tried holding in the power button for extended periods of time. No matter what you do, the laptop has no response of any kind...no lights on its panel or anything. Meantime, the power-LED on the power adapter continues to blink green on-and-off constantly. This laptop has worked perfectly and we've never had any problems with it of any kind. The only thing that happened was my wife powered it off yesterday morning and it's been dead ever since. Ideas?
