Keyboard does not not on my macbook pro

Hello. I have an early 2011 MBP 13 inches. I've never touched the battery on my mac, even if I did some updates in the past. Now just tonight. I was using the mouse as usual for some reason any. I'm not able to operate the keyboard and the touchpad after that I went to the bathroom. When I came back my mac was in screensaver mode.  I did a reformat my hard drive and reinstalled OS X but that did not work. I finally opened my mac and remove the connector of the battery and I reinserted the connector again after a few minutes. My keyboard and touchpad are reworked. My question is this. The bluetooth had something to do with it? I made the correct procedure in the face of this problem?

Remove the battery reset the SMC.  Power failure all the correct step would be but the 2011 MacBook was designed with a non-removable battery and there is an easier way to reset the SMC.  If a keyboard or the built-in trackpad stopped working because it is not recognized then reset the SMC is the first step to take.  If you have a USB port or port thunderbolt also stops working without a connected devices are recognized, an SMC reset should be the first step.

  • HP deskjet f4280 does not scan on MacBook Pro Mid 2010 (MacBookPro7, 1).

    Hello!

    I have a hp deskjet f4280 and when I try to scan from my MacBook Pro Mid 2010 (MacBookPro7, 1) the scanner and image capture app froze... I was watching the issue closely, and I think that it is due to a problem with the "HPscanner.app" when he's not on the preview, it freezes and State to 99.8% of the CPU usage...

    The problem is that in this computer. I have another mac, MacBookPro8, 2, and it scans properly and without any problems.

    Any idea?

    PS / else and if anyone is wondering... I have the latest version of the drivers.

    Thank you for your proposal!

    I finally comes to enter in safe mode to check if it I could scan. It scan Scanner normally. When I restarted the machine, it does not freeze over.

    Thanks anyway. I'll keep your solution where the question arises again.

  • Key ESC Office keyboard does not work on desktop running Windows 7 Pro 64 x

    Key ESC Office keyboard does not work on desktop running Windows 7 Pro 64 x

    Now, it's a boring, which several other users have reported under different threads. Because I couldn't find a post with quite similar symptoms, I made my own topic.

    I am running Windows 7 Professional 64 x on an old one (Intel Quad-Core, 4 GB RAM, 524 GB HDD - in case, for reasons unknown to me, someone needs to know it...) , DellXPS system. Not more than a few weeks ago my home button keyboard unresponsive on this system.

    I did a lot of troubleshooting, but these measures have been carried out:
    * Tested keyboard on the other system, touch ESC WORKS on the other system
    * Reinstalled keyboard and USB drivers on the XPS system, ESC key does NOT WORK on the XPS system
    * Connected to a never-before-used USB keyboard, ESC key does NOT WORK on the XPS system
    * Opened and cleaned the keyboard, tested, Escape key WORKS, Don't DO NOT WORK on the XPS system
    * Tested in various applications: Desktop (Esc will close the start menu), Photoshop, Vegas, Notepad, games full screen OpenGL,Escape key does NOT WORK on the XPS system
    * Google for possible solutions, none found...

    Note: Highlights show where the ESC key does not work. I am troubled by the XPS system.

    In case you missed it my list of troubleshooting steps, the ESC key works on another computer of Windows 7 system.

    I have to still garble my self through the registry in the hope that someone might have an idea of the steps to follow before I lose a day to see the things that I honestly know squat. Please help if you can; What could be the issue/common application that separates this key in the Windows world and how could I solve this problem?

    Thank you in advance!

    For reference,.
    No major changes have been made since the keyboard unresponsive with the exception of:
    Updates to FireFox (including modules Ad-Block Plus, NoScript, which have also been updated).
    Windows Update
    A 10.x MB World of Warcraft patch/update on a keyboard AFTER week unresponsive

    Already installed the patches StarCraft II and World of Warcraft, which none touched my keyboard to my knowledge. I finished almost all of StarCraft II and had no problems...

    I know it's a bit old, but I was living the question myself.  Thought I had found the problem and it was fixed but then it happened again.  Came to find out (by closing a program and test the ESC key) it's because Photoshop.

    With the help of Photoshop, which could match the case you mention.  Not only that but I did a search ('ESC' does not not Photoshop) and stumbled on some answers/solutions workaround for it.  One is to use SHIFT + ESC ESC does not work.

    Hope this helps someone.  I fell it using my original research ("Windows 7" BSE "ESC" keyboard does not) and know that others are likely to see.  If you have not already learn the cause, in the year + since your original message, then voila.

  • El Capitan keyboard does not not after reboot

    I have a Macbook Pro 13 inch with OS X El Capitan 10.11.6

    After one of the recent improvements, I met a problem, if I take my mac, the keyboard and the trackpad to respond enough lag (if I constantly try to move the cursor, he'll have a time and then for like half an hour it will completely stop responding and after this the other repeats). It only happens after reboot and only on the login screen. So if I put my mac to sleep and then wake up, everything will work perfectly. Same thing if I managed somehow to connect, once the keyboard and trackpad respond correctly. The only button that works fine after reboot is the power button, but it doesn't help much, because it charges does not solve the problem somehow: as soon as the user selection screen, keyboard and mouse stops responding again (or should I say "start answering from time to time").

    I saw lots of questions here on the keyboard does not not after waking up, but as you can see, this isn't my situation.

    Try again in Safe Mode.

    Start up all by holding down the SHIFT key. It takes five minutes longer because it is a disk first aid on the way up, and you MUST provide your user name and password, even if you normally the automatic connection.
