TimelineX 5820T no power

My laptop has no power. Wont power on with just battery, no indication that it is receiving a charge. Won't power on without battery installed. Power adapter seems to be working (it has a green light). I have no multimeter to test it with to confirm. I unplugged it, removed battery, held power for 30sec, re-installed battery then power cord and still no love.

I had a browser open to view my fantasy football team and also watching a live feed of nfl football on justin tv. The battery was down to almost 10% so I plugged it in. I left it alone for about 30 minutes and went back to it and tried to power it on. Nothing.

The only lights that do show up is after i re-installed battery and cable the blue led for the battery will shine. I press start and the led on the power switch will flicker, as well as the power on led.

I am desperate to get this thing running. I am leaving out of town on Friday and need to do a presentation on it.

Well the verdict is in. It's the motherboard, according to the shop I took it to. It's a shame because I really liked the laptop. I'm having a hard time finding a suitable replacement for it. The features I enjoyed the most about it was the thin and light design, good battery life, and brushed aluminum finish.

Does anyone know of another laptop in the $6-700 range that can compare to these features? I am very reluctant to spend good money on another Acer.

Does anyone recommend replacing the mother board? The shop I took it to quoted me a price of $385.

 

Motherboards for this model cost some $200 on ebay and you should be able to replace it yourself to keep the cost down.
