Hi usernamenn,

If its just the letter "t" that doesn't work (but all the rest work OK)  then it's usually a physical problem with the letter concerned. Check to see if there is a " foreign body" stopping the key activating correctly.


Foreign bodies in the form of biscuit crumbs, old staples, dust, or food/drink residues can some time be to blame.


1 A first good strategy is to close down (shut off) your computer completely (not a hibernate/sleep) and then remove its main battery) then unplug your computer completely and hold down the " power on button for 20 seconds as this will discharge the capacitors.  With the computer open, invert it and tap (gently!) on its base to see if anything can be easily dislodged.


2 next step is to try an "air duster" a can of low pressure compressed air marketed to clean computers, try to get the nozzle tube in under the key from all angles whilst it still inverted.


3 If this fails then remove the key, but be careful as trying to prise it off may damage the delicate plastic clips that hold it on!


4 If all this fails then its probably a new keyboard required, but before spending any money and also before starting steps 1,2 and 3 above, plug in a USB keyboard, then switch on your laptop computer and check that the letter "t" and all the rest work Ok


Post back if you need any amplification on this.
