How can I replace the port on the monitor where the keyboard cable plugs in on a 9" polaroid internet tablet?

first of all, make sure that your tablet has an On the go USB port or data port if not, it can only be used to charge. If you connect our tablet to a computer usb port, and your computer recognises it, then you have a data port.

If you plug in a usb memory stick, and your computer can not read it, it does not have a USB to go port.
Also, some Cable adapters are On the Go wired, and may not work properly.
It may also be that the USB port is not providing enough power from the tablet to the keyboard. In that case, buy a split power usb cable, and plug the red (power only) into a usb charger or powered usb hub.

Hi they r cheep to buy on E/BAY APROX $23. THIS WOULD B THE BEST WAY TO FIND OUT IF IT IS THE KEYBOARD OR YOURE TABET THAT IS AT FAULT CHEERS

The charger plug should plug into the mini-USB port. This is the same port for the USB cable that would connect to the computer, and in fact the tablet can be charged from the computer if the computer is on.

If it is a standard USB keyboard, that is probably your problem. Tablets are not like Windows PCs, where everything USB is plug & play. Tablets usually run some version of Android as their OS, and manufacturers may or may not support keyboards. If they do, they will specify what keyboards will work with your tablet. Tablets are a lot like Apple products - not everything off the shelf will work and sometimes it must be manufacturer's products only.

Try plugging in the USB cable between the tablet and the USB port of a PC. The PC should recognise and install the correct driver software.

On the Tablet you need to choose between "debugging" and memory flash disk. Choose the Memory flash disk option on the screen.

The Tablets internal drives will then appear as drives on the PC if successful.

Some PC's cannot install the correct driver software, so you will have to download a generic android one from the Internet.

i have a password to use tablet someone took my keyboard off and now i can't open my tablet

Sometimes, if you plug in the power cord, a tablet will turn on automatically. If that doesn't work, the button will either need to be replaced, or you will need to get another tablet. A lot of the cheaper tablets like Polaroid, Coby, and the like are made to be throwaway devices. Once they break, it's more cost-efficient to just buy a new one a lot of the time.

well thats strange,, the tablet has 1 USB 2.0 port and the keyboard connects to that port as its standard.. Its a standard port so all usb 2.0 connects for it is standard.

is what u have right ??? try turning the connector around.. It should fit.

I suspect it may be a problem with the video cable coming from the convertible tablet, up through the hinged support for the LCD screen, AND/OR the screen Inverter.

I would like you to connect a VGA monitor, to the VGA port on the back of the convertible tablet. The VGA monitor will now be an External Monitor.

[ Looking at the rear of the convertible tablet, start at the Left side.
Vent, USB port, Monitor port. The Monitor port is the VGA port ]

The VGA monitor can be a CRT type, (Looks like a small TV), or a flat LCD screen monitor with a VGA cable.

Notebook OFF, monitor OFF, connect the VGA monitor to the M275's VGA connector. (Port)
Turn the monitor on. If a CRT type, allow it to warm up.

Turn the notebook on.
By the factory default settings, whatever is shown on the convertible tablet's internal monitor, should now be shown on the external monitor.
(VGA monitor)

If not, press, and hold down on the Fn key (On the bottom row of the Keyboard, all the way to the Left), and tap once on the F3 key.
(Top row of Function keys. The F3 key is the Display Toggle-Over Key )

No graphics shown on the external monitor? Hold down on the Fn key again, and tap the F3 key again.
There are at least three options available;

1) Convertible tablet's internal monitor - ONLY
2) Convertible tablet, AND external monitor
3) External monitor - ONLY

If graphics are fine on the external monitor, you have a problem with the video cable, and/or the screen Inverter. At this time we will bypass the LCD screen, and come back to it.

At the bottom/middle of the tablet's LCD screen, is the Hinge. The Hinge Cover is 'T shaped', and has one single Philips screw holding it on.
If you remove the screw, and the Hinge Cover, you will see two wire harnesses.
One Black, the other White.

See that these two cables are plugged in tightly to the connector.

After checking this step come back in a Comment, and state your findings.
