Q: Some keys on Macbook pro mid 2009 do not work.

Currently I am using Macbook Pro Mid 2009. Some keys do not work properly. Those keys are "L" and "O", the others work just fine.

but interestingly, when I type 'o' or 'l', it doesn't work at all; but when I type ' Shift + O', it works properly. More importantly, it works all the time when I type together with other letters. For example: I simultaneously type 'l + k', and it appears as "kl"; or i type 'l' and 'o', and it appears 'lo'.

Is it a software or hardware problem? I don't want to spend several hundreds dollars on it as it is old already.

Ur comments are really appreciated.

MacBook Pro, OS X Yosemite (10.10.2)

Hi P.rith,

Welcome to the Apple Support Communities!

I understand that two keys on your MacBook Pro keyboard are not functioning as you would expect. In this situation, I would recommend reading over and working through the troubleshooting steps outlined in the attached article.

Hello P.rith,

Because this issue is still happening, I would further suggest opening the Keyboard Viewer to see if the keys are even being registered when you press them individually. The attached article will walk you through opening the Keyboard Viewer; please let me know what results you have.

Have a great day,

Hello P.rith,

The next troubleshooting step I would suggest would be to isolate this issue by testing in a new user account. Please follow the instructions in the How to troubleshoot OS X user accounts section of the attached article. The article has not been updated for Yosemite, but you can use the same instructions that are available for OS X Mavericks.
