7720 Travelmate turned off and startet again only once

I can not start it, nothing hapens just a peace of metal with plastic, just see the light that battery is charging and even it disappears when i push the start button.... nothing works... i am calling techsupport

  • aliaksei_gol Sep 08, 2009

    I wrote already... nothing works...turn on button doesn't react at all

    with battery, without battery...

    the only reaction that is is when i turn on a cable from Power Supply, and there is a battary inside it shows me that battery will charge, but when i press the turn on button even this one will go off....

    so that is the only thing i can do replug the powersupply and the charging light is again on, and then press the power on button and it is off again...

    computer itself doesn't react at all

    i guess that is hardware stuff problem like any of those on motherboard:
    Bad voltage regulator chip, bad capacitor, bad resistor, bad BGA chip (Ball Grid Array), bad diodes, bad thermal chip.

Try without battery.
If it set the problem, let me know

Check power supply if green led lights up
if not try other power supply if yes
Tell me if you ear or see anything on the screen.

I changed the battery in my Nebo and now it won't turn on it takes one ICR 18650 2200mah 3.7v battery.

Check the little mother board. There is a peace that sticks out of the black plastic housing and makes contact to the inside metal frame of the flash light. Just gently pry open plastic housing that is behind led housing. You should See a sq opening on the side of the plastic housing. If it's missing a little contact there then solder a small peace of solder where the contact was. Make it just big enough to where when you slide It back in, it makes contact to body of the flashlight. What's happening is it connection to the negative is broken. I would take the part back out but I'm afraid if I do it may brake off the solder part. It was a tight fit but that black plastic peace that has the spring sticking out is that part. It should slide right out. After you unscrew the led housing from the unit. On my flash light, it's the board that has both usb connections on it. Again it's where there is a sq hole on the side of the black plastic housing that contains the usb ports. There will be a hole there for no obvious reasons. That's where you solder on a peace of solder to where it barly sticks past the plastic. Good luck. Sorry for bad pics. My light is the iPeotech 3200. Should be same principle for many different ones.

My car will not start. I thought it was the battery because it startet to take a while to turn over and then it didnt turn over and i started it with another battery but i had to hold the key for a while...

It's most definitely the starter. Have it replace and when you do, check the wiring. If this was at all helpful, please rate. Thanks for asking.

White screen on Acer Travelmate 7720

most likely you have a faulty LCD screen, the only option u have is to replaced it or u can use a external LCD screen to act as screen for your laptop. you'll be needing a VGA cable to connect your laptop to any LCD screen available.
