Attaching to multi media projector issue.

When I attach an NEC projector to the laptop, I am unable to see the content on the laptop. Another time, I tried to show a DVD through the projector. I saw my screen saver on the wall and the movie on the laptop.

Why does Lenovo Thinkpad e145 not turn off.red light flashing


For this particular scenario, it is most likely the system board. It is probably still a good practice to pull the battery and AC and try to reset by pressing and holding the power button several times, for several seconds each time, and then re-attaching AC and try to restart.
If the symptoms remain, please contact service for assistance.

My Microsoft wireless mobile mouse 3000 isn't responding, both the lights are on (the receiver and mouse) but its not tracking on my laptop screen. I tried re-syncing it buy not luck. I also tried...


Make sure there is nothing touching the trackpad on the laptop, as that will stop the mouse functioning correctly.

You could also try attaching the receiver to a different USB port on the laptop, to make sure it isnt a dead USB port.

Lastly, you could try downloading and re-installing the drivers from http://support.microsoft.com/kb/258785

Some keys on my laptop`s keyboard doesn`t work such as g, h, backspace, fn and the windows button, what can I do?


Hi, if you spilled liquid on the keyboard then it probably needs to be replaced,
Try this... you can remove the keyboard by removing certain screws from the bottom of the laptop, then you open the laptop like if you are using it look to for sliders around the keyboard edges or if it just snaps in place, use thin flat screw driver to carefully remove the keyboard but do not pull far.. it should still be attached with a wide flat cable to the main board... now lets try to remove the cable completely and re-attach it ( when removing the cable use your small flat screw driver to pull the plastic connector snaps from the sides of the connector to loosen the cable and be careful not to break the connector, when attaching back put the cable in first and hold it while you push the connector plastic back in place)... try the computer to see if the problem is gone, if not then order another keyboard and replace it. best of luck

Can't find software to get mouse to work


Most mice will function by simply attaching them... Mice that have additional buttons (beyond the three, including wheel) will likely need software drivers installed to support the beyond three functions. Look up your specific mouse model with the manufacturer.

I have a dynex wireless optical mouse but my laptop will not recognise it


Have you installed the driver for the mouse? Did you install it before actually attaching the mouse's USB receiver? The driver should be installed first. You can download it here:

http://www.dynexproducts.com/productSearch.html?query=wireless+optical+mouse&mainSearchButton=


Scroll down to "Dynex Wireless Optical Mouse" and click on "English" next to "Driver:" in order to download it.

If you've already installed the driver and your computer still won't recognize the mouse, press the Connect button on the receiver, wait for the light to flash, and then press the Connect button on the mouse. The light should stop flashing and the mouse should be ready to use.

Can I use a V220 ona Desktop computer


It will work fine on your desktop.
It is only sold as a mouse for laptops as it is compact, but it is a standard wireless mouse with a USB RF Receiver. Plug it in and it should install and run fine.
If you have problems where it isn't 100% responsive try attaching the RF Receiver to a usb extension cable so you can place it next to your mouse pad. The closer it is the better the reception.

Keyboard keys that have purple numbers are locked. Can't type.


Your "Num Lock" is on.
Look for the num lock key (it's similar to the "caps lock" key in function)
If the "num lock" is blue, you may have to hold a blue "fn" key when you press num lock

There's is probably a light at the top of the keyboard that'll tell you when num lock is on.

Attach HP PS2 Keyboard to Dell Laptop


hmm, Interesting
Because the Laptops mostly do not have the PS2 Port,
if you are using the converters connecting the USB to the PS2.
then It may be the junction related issue.
so find a USB mouse and connect it directly or try with another Converter.
that should work.
