SOURCE: Power supply problem

This is going to be with the power management system on the motherboard. These are the classic text book symptoms of a failed power management chip. Few shops will be able to fix this, most just say replace the motherboard, you might get lucky and find one in your area that can fix it, if not then you will need to send it to Acer for repair.

SOURCE: Power adapter port on motherboard fried, cannot

Get you an external battery laptop charger and charge the battery that way.  Your gonna have to open this puppy up and replace the power port IC board if you want to charge by AC cord. Your non factory charger could have fried the board.  The board isn't too spendy, but you gotta know what your doing or you will crack the case or damage other parts when opening this thing up.

SOURCE: How do I increase the power to the USB ports on a multimedia keyboard with 2 USB 2.0 ports?

What JonSnell says is true. When an USB port on a computer can deliver 5 volt, it is limited to 500 mA or 0,5A. Not every port on every computer will be able to deliver power. It is dependent on how the manufacturer has made the computer. When a Laptop with 4 USB ports, will be used to charge your equipment it should drain 2 A and would empty the battery very quick. So better not try to use a laptop for that.
A driver is meant, for the computer to make it possible to communicate with the hardware you connect. Communication is one thing, completely separated from the possible power a port can deliver.
There will be no driver, that can change the maximum output on the USB port, because the computer hardware will limit it on the 500 mA. Even on a desktop PC. So most modern smart phones or tablets need more power than a PC can deliver.
To charge them, you better use a charger, or if you want to sync and charge the battery in the same time, buy a USB hub with an external power supply. Be aware, most power supplies only can deliver 2 A, so don't put more devices to charge then the 2 ampere the power supply can deliver, or you will get the same message.

The limited directions tell me to charge my Garmin 1450 for at least 4 hours. How is that done without a charger? Will it charge with the computer cable? It seems that your site will not allow me to...


Hello,

The nuvi will accept a charge when connected to a computer if the computer connection is done through a powered USB port.
Garmin part number 010-10723-00 which is an AC power adapter is also available for charging the unit.

How do I recharge the battery on my Garmin Nuvi 255WT? I would also like to know how to update my Garmin?


Hello,

Recharging the battery is done by connecting the nuvi to a vehicle power cable in the car through the vehicle power accessory outlet or cigarette lighter.
The unit can also be charged via a powered USB port off your computer via the USB power/data cable or an AC power adapter through the USB power/data cable.

Garmin gps powers off even when fully charged


If you're "recharging" via the car charger - you might want to try charging via USB jack on your computer - or AC adapter (if your GPS shipped with one) for 5 or more hours.

Many Garmin units develop this condition when used strictly in the car / cigar outlet power source. While connected to your computer, you should go to Garmin's website and download, install & run the "webupdater" software. When complete, your Garmin GPS will have the latest firmware and patches to the software (not maps!).

After charging via USB or AC adapter, your GPS should stay on. If your GPS turns on via a slide switch on the top, Slide the switch from OFF and hold in the ON position for 10 seconds before letting go of the switch. This should force a "boot" on the GPS.

If you're unable to get the device to power up, contact Garmin Support to determine if your device is affected by a a recent battery recall or if there are other suggestions they have to solve the problem.

I hope this helps!

My garmin ran out of charge and when it was plugged in to the car charger it says loading maps then stays on the garmin page and goes no further...


Disconnect the nuvi from the car charger and connect it to your computer's USB port with the supplied cable (or any USB cable you have that fits it), and leave connected overnight (8 + hours).

You should be able to get the GPS to start up as expected after charging via USB port. if this happens again, simply repeat.

Good luck!

Can I charge my Magellan roadmate with USB cable connected to the computer?


It depends on the Roadmate that you have. :
- If your Roadmate has a separate plug-in port for charging your unit IN ADDITION TO a USB port, then no, your Roadmate cannot be charged using your computer via the USB cable.
- If your Roadmate only has a USB port available for charging your unit, then yes, you can charge it via your computer via USB.
However, please note, according to Magellan, charging your unit using your PC via USB can take up to 12 hours to charge vs. 4-6 hours when using the vehicle power adapter.
FYI: This is mainly due to USB constraints on pretty much all electronic devices. USB cannot carry the same amount of power to a device. It uses what is commonly known as a 'trickle' charge to recharge a device. It carries much less current than a full-blown charger (like an AC power adapter).

When plugged into pc get error on pc power surge on usb hub port


Some computers have a limited power capacity on the USB ports, another possibility is that your gps battery is too low to be charged via the USB connection, try charging it with a wall or car adapter first, then connect to your pc.
