Satellite Pro C650 - arrow, slash, and z keys are not working

Can any one help - my slash keys, arrow keys, z and question marks have stopped working.
I have seen several other posts on various forums for exactly the same combination of keys.
I have a Satellite Pro C650.

Sounds like a keyboard malfunction.
Can you use the external USB keyboard properly?
If you did not notice the same problems using external keyboard, then I would recommend replacing the internal keyboard.

Hi,
While this could be a hardware issue, it's always worth trying the following.
Open windows Control Panel, open Device Manager, expand Keyboards, right click the entry 'Standard PS/2 Keyboard' and select Uninstall.
Shutdown the notebook.
Then unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Regards,

Try an external keyboard. If it works, you need a new internal keyboard.

Satellite C50-A-15Q - arrow, question mark key and z key are not working

I have a Satellite Pro, C50-A-15Q. All keys were working fine yesterday, today I turn the laptop on and the arrow keys, question mark key and z key are all not responding. Any idea how I can fix this?
I have tried turning the laptop off and on, hoping (naively) that this would fix, but to no avail.

As Tom already wrote, it is not easy to say for sure if this malfunction is result of defective keyboard or maybe keyboard controller. In my opinion troublemaker is the keyboard itself.
Have you maybe updated BIOS or done anything that could be responsible for this?
I presume your notebook is pretty new model with valid warranty so best option for you is to contact nearest Toshiba service provider and ask for help.

My O, L, and '.' keys are not working!

I have a question. I have a PowerBook G4, 1.5 GHz, Aluminum. Recently, my "o", "l", and "." keys are working intermittently. Half the time, they do not work. This is not a software problem as I have an external keyboard. Does anybody know what's going on??? I don't.

Sounds like a cracked trace on the keyboard PWB. Best to just replace the keyboard. You might get more information at this link:

Replacement can be a bit involved:

In this case, the Titanium models have the Aluminum models beat, as replacing a Titanium keyboard is a 2-3 minute process, tops.

'u' 'j' and '7' and '!' keys are not working?

The 'u', 'j','7' and '!' are not working. The phone has recently been repaired after getting wet - new battery and screen. Any ideas why not working?

Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears)
See if that helps.

I have Late 2011 Macbook Pro and zxcv keys are not working?

I have late 2011 Macbook Pro and the zxcv keys are no longer working. Once I connect USB keyboard I can utilize these keys. Do anyone have solution?

How did you try to use Acitivty Monitor?
Open Activity Monitor, choose "All processes" from the list, and sort processes by CPU usage. More likely than not, there will be task using up good bit of CPU.
You could also try resetting SMC:

Caps lock, delete and tab key are not working on my Apple wireless keyboard

I see that a lot of users have had this same issue. I have tried all the "tricks" suggested, but keys are still not functioning.

Try a smc reset
http://support.apple.com/kb/HT3964
Try a pram reset: power off, power back on holding the keys: option, command, P ,R (no commas) press them before the start chime, and hold them till you hear the start chime 32 times, then release and reboot.
If still no joy try a safe boot, power off, power back on holding the shift key. Continue to hold the shift key till you see the progress bar, let it finish booting, and see if t works.
The code thing is wierd.
If none of these help your issue, bring it to an APPLE store or a AASP and have it checked out it have a bad top, or logic board/HD.

Is this a hardware problem?

Then I wouldn't think it's to do with the Arch, updating does not stop parts of the keyboard working for the bios as it's separate firmware. When you can access the bios after first turning on, your PC has not yet accessed the hard drive to load the drivers for the operating system yet. Also as far as I'm aware Arch (or any other operating system in fact) has never updated the bios firmware.

Hello, I have an Apple wireless keyboard linked to an Ipad Air. The M J U and 7 keys are not working, Is there a solution, Thanks

Hi, Has anyone else encountered this problem. I see mucg discussion of this problem with MacBooks, but none relating to use with an IPad.
Thanks

I am having this problem as well. I hate to just wait and hope Apple will fix the problem, but I'm not sure what else can be done. We can't be the only people experienceing this, can we?

Keys are not working

my keys on my mac book pro are not working properly. the shift and control keys are not working and do not show up in the viewer.
any helpful hints on how to get them working?

seems like various different keyboard issues, requiring different solutions.
however, for what it is worth, I DID resolve a related issue. In my case, the problem was definitely SOFTWARE related. "s" key stopped working, as well as a couple of keys on "number pad", including "enter" key, etc.
when i did time machine backup and transferred to new computer, i found that the "s" key (and others) STILL NOT WORKING on new computer!
i should also note that, before the transfer, i had also tried different keyboards on old computer and had same problem: no "s" key, etc.
this made me think problem had to do with that old computer, since same problem with different keyboards. but, after problem remained after transfer, it was pretty obvious that I had transferred the problem to the new computer, which made me conclude the problem was SOFTWARE and NOT HARDWARE.
well, first thing i always try (as IT guy) is to set up and test new Apple user account. when i set up a new test account (administrator; not standard or guest, etc.), I noticed that the "s" key was WORKING (and I assume others - new keyboard was NOT extended; so no number pad to test those keys). When I logged back into the old account, once again, the "s" key not working.
i duplicated all of this testing on the new computer; so THE PROBLEM WAS DEFINITELY A SOFTWARE PROBLEM WITH THAT PARTICULAR USER ACCOUNT. I guess somehow an ACCOUNT can be specifically affected (corrupted) in some way that other accounts are NOT so affected.
Doubt if this would apply in case of UNRESPONSIVE KEYBOARD (which seems to usually be HARDWARE related); but in the case where only SELECTED KEYS are not working, you might want to simply try setting up a NEW USER ACCOUNT.
Unfortunately, Apple has NO easy way to transfer files between accounts. But, of course, I would likely NOT want to do that anyway, in this case, as I might end up transferring software problem to the new account. Therefore I DID have a bit of work to do, in terms of tranferring PICTURES and MUSIC to the new account from the old, etc. But that seemed minor compared to working on a computer with certain keys not functioning!

Hello, how much did you pay when some parts of the keyboard keys are not working properly due to accidental spilt of tea?

I accidentally spilt a tea on the keyboard of my Macbook Air 11'. I managed to wipe the keyboard and saved my laptop. However, I noticed that the Spacebar, Shift and Command keys are not working as it should be. It's like something's stuck inside that makes these keys hard to press as usual. I refered this problem to Amsys, Berwick St London, as the reservations in Apple Stores are full. Do you have any idea how much is the cost for diagnosis and repair if ever?
Please help.

if you spilled a good bit of tea, its a serious problem, yes.
it got inside, and will corode, and bad things will begin to happen.
Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.
