AC adaptor blinks when plugged in and wont even turn on...
Im really puzzled as my 3 year old acer 1694WLMi suddenly zapped itself dead after i left it untouched for about 3days. i kept it in my room at room temperature and also left it unplugged. a few days later i tried to turn it on it doesnt even shows a blinking light but the external AC adaptor just shows a dim blinking light....

Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.
1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.
Hope this will help...Thank you for using Fixya...
Try firstly removing the laptop's
battery as it may be at a critical voltage and the system will not
start because of it. Plug in your ac adaptor and monitor what
happens. Does the power light illuminate? If it does it should then
boot up, if it doesn't, try a known good ac adaptor before going any
further. If the adaptor is fine and the laptop still won't start, then you have a mother board fault
and should contact a dealer/repairer for further advice. Hope this
When you plug the laptop to the power adapter, you should see the indicator led lit up telling that it has good connection to the ac adaptor. It wont turn on because either there is a loose connection to the power adaptor and hasn't been charging the battery, or the power adaptor itself is bad. Check the power plug with a miltimeter, it should be around 19 Volts.
Sounds like you killed the motherboard. Find a local repair shop or someone on craigslist who will diagnose it for free. Wait while they do it, should only take 5-10 minutes to confirm your worst fears.
The battery needs to be taken out once in a while. It is possible to use the ac adapter and power cord without the battery to power your laptop. Please press on the power button for 10 seconds for your computer to turn on. Check if you can see any message on the screen.
I had to buy an new ac/dc plug piece off of ebay (cost only like $3 bucks) to sodder onto the mother board of my Acer. Somehow the little plastic/metal piece you plug into your computer comes off the mother board really easy. Acer wanted me to purchase a whole new mother board (at frigging $350), which, frankly wasn't an option. So I bought the little plug gizmo, soddered it on, and I'm doing good now.
sounds like you have an intermittent problem with your AC adaptor or dc input jack. Does the light on the AC adaptor light up when you plug it in? If it does then your dc input jack may be faulty. If the light on the ac adaptor does not light then replace the ac adaptor.
