E-100 AC adaptor faulty??

Bought my E-100 used about a week ago and the unit charged up fine (Green LED on while charging). @ days ago I plugged it in to charge and no Green LED. Thought maybe the LED itself died but the unit WASN'T charging and finally wouldn't go on at all. I'm taking the AC adaptor in tomorrow to see if it's what's broken. If it isn't, I read some posts that talked about jiggling the battery lock. (I've tried that, no dice). Is this a common problem with these units? If so, is it fixable? Lee

It may be your main battery is dead. I had the same problems and had to replace the main battery and everything worked fine!

I have a new e627 used only once before today. Battery connection was partially out and screen indicated low battery. After five minutes screen went black and now I cannot power up.


Maybe your battery is totally drained.

Try to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.

Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.

AC Adapter issues Q & A.


<p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small "camera flash charging" sound, stabilizing at 19v. When charging, it repeatedly makes the "charging sound" Faulty AC adaptor? Or Faulty battery? Or Both?<br /> <p><b>A. </b>First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It's either broken or loose. It's a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.<br /> <p>It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord.

Tomtom ONE will not turn on


it may wel get power light on but if the battery has collapsed then it will take forever to accrue a minor amount of charge. USE the AC adaptor to charge it and see if whilst it is connected ( after hour) that you can turn it on and get a display.
You could also get a new battery for it if it does respond. failure could indicate that battery acid has leaked and done damage, even Lion batteries break down

Battery charging status remains constant (not increasing)


I've have seen a number of different batteries do this, and I recommend what is called 're-conditioning the batteries. Do this by running the battery completely down to 0%. Then do a complete re-charge of the battery to 100% (if possible). If it charges to 100%, run it completely to 0% again and then recharge it. If it does not charge to 100%, then you may have a faulty or old battery which will need to be replaced. The AC adaptor and battery have circuitry in them and might be retaining incorrect info in them. They can be reset by unplugging them for a few minutes and then plugging them back in. There might be a specific sequence of what to unplug and when, in order to reset this circuitry. Try a couple of them. (ie. Battery, AC adaptor in to battery, AC adaptor into the wall, etc.)

Let me know what happens. Binary Bob

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. Good Luck!
