Help my laptop seems to have no power when turning on.....nothing happens...do I need a new battery or power plug???? Please help?? Need computer for school!!


hi generally most new laptop have a internal shut off if there is some kind of power surge, here is the solution to try it works on most laptops these days but dosnt get documented enough
1 Removed the battery and power cord from the laptop
2 Press and hold the power button on the laptop for 30-60 seconds ( the longer the better)
3 Connect the powercord to the laptop but leave the battery out
4 Try and power on your laptop - if it turns on you are good to go just reinsert you battery and repeat if it happens again

AOC L26W861 LCD TV : 1. When TV is turned on using remote, it just recycles through all the pre-programmed channels 2. Unplugged the power chord several times but is still does the same 3. Power button on...


Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

I cant get my mda to turn on i hold down the power button for a while but it wont turn on i charged it for 3 days and it still wont work what should i do?


Mda Vario's don't charge when turned off, heres what you do.
cut wire off a usb lead the small end strip the red and black wires, put the red wire onto the posative connection where the battery is it tells you what side is posative and negative on the battery, use black with negative and red with posative making sure that no wires touch the other metal strips in the phone, replace battery plug usb into computer and start up the mda and wait for it to boot. once turned on leave to charge as it will charge through the wires connected to the battery, after 10 to 15 minutes plug in the actuall charger and try to remove usb wires without taking battery out. if that is not possable it is ok as the battery should have enough power to start up once it starts leave to charge and always keep some charge in the phone.

My T-Mobile MDA won't turn on or take a charge, battery was low


I had the same problem, but got the idea to "jump start" the battery from Googling the problem. At night, I had turned off my MDA to charge the battery and then in the morning, couldn't revive it. I removed the battery from my MDA, and determined which battery terminal was positive (far end of one side) and negative (far end of the other side) by using a multi-meter. BTW: Battery was still @ 3.5V (okay…battery was still alive, if just barely). Then, I found a 5V DC charger (5W Max output = ~1A) from my bluetooth headset. I used one wire (CAT5E) and connected it to the negative side of the adapter (outer sleeve - again, verified by multi-meter) and another wire to connect to the positive tip of the adapter. I had to strip about 1/2-inch of the insulation off of the wire on the DC adapter side, and about 1/8-inch of the wire on the battery side. Plugged in the 5V DC charger and then I touched the negative wire to the negative battery terminal and held it there, while I touched the positive wire to the positive battery terminal for about 30-45 seconds. Put the battery back in the MDA, started it up, and now it's charging on the regular MDA AC Charger that came with the phone. Problem solved.

I’m happy to assist further over the phone at https://www.6ya.com/expert/daren_80e8def41854e57e

UNCOMPLETED MDA UPDATE


this is a sw boot up screen. this is what the screen will look like with no sw on the device, so you guessed it....the download was unsuccessful and corrupted the firmware.....if you tried to reinstall the sw again, and it does not work, you might need a new phone....contact t-mobile to do that.....OR, you can try to do a master reset by pressing the sw keys.

to do that, turn off the phone, and press and hold the soft keys (buttons located beneath the touch screen that have the lines on them on top of the green call button and the red end call button).....while holding these down, press the power button for 3 seconds and release the power button.....all this time you are holding those soft keys down....the phone SHOULD turn on and go to a black screen with white writing.....at this time you can relase the two buttons......press the green button and reset. if this does not work.....my friend, you need another one......good luck!
