Mac mini loses mouse and keyboard after sleep.

Hi Everyone:
I recently bought my Mom one of the new Mac mini (I'm a PowerBook user myself), and she's running into some puzzling problems which, while minor, are sufficiently annoying as to confuse poor old Mom.
The system egnrally runs fine after you turn it on, until it goes to sleep. After some undefined period in sleep mode, the Mac mini appears to "lose" the USB keyboard and mouse which is plugged into it. If you press a mouse button or a keyboard key a few minutes within the system going to sleep, the system will wake up and both will work. If you wait a longer period of time (say, 20 minutes or longer, although I haven't sat and timed it at all), pressing any key or mouse button does nothing, and you have to wake it from sleep by using the power button. Once awake, the keyboard and mouse do nothing. The only way to get them back is to unplug both of them (the mouse is chained through the keyboard as the other Mac mini USB slot is used by Mom's UPS), and plug them back in so the Mac mini can re-detect them on the bus, after which everything is happy again until the system has been asleep for too long.
Has anyone experienced this? Both the mouse and keyboard are genuine IBM (as in: made by International Business Machines), although are several years old (I bought them when I worked for IBM, and IIRC they were amongst the first models of USB keyboards and mice that IBM offered, if not the first).
In the interm, I've lent Mom my Apple Bluetooth mouse and keyboard, which has (as you would expect) worked flawlessly. This problem may "solve" itself -- I'm hoping to take Mom out later this week to buy her own Apple Bluetooth mouse and keyboard at the Apple Store.
The other problem, however, isn't as easy (or necessarily as cheap) to fix. Again after the system has been asleep for some time, it often (but not always) changing the resolution of the monitor when it wakes up. I have the mini set to use a reasonable 1024*768, but sometimes when it awakes it will suddenly be set to 800*600 or 832*624. Sure, you can change it back, but that's major surgury for Mom (and I'm moving cross-country next week, and won't be able to just "drop by" to fix system problems). The monitor is an Ambra SVGA model (Ambra was a brand-name of inexpensive PCs that IBM sold some years ago), and never had any such problems on her last (Intel-based) system the mini is replacing.
The whole purpose of the Mac mini is to "bring your own" Keyboard, Mouse, and Monitor -- but in our case the keyboard and mouse don't work at all after sleep, and the monitors resolution gets dynamically changed after sleep. Has anyone else encountered this situations, or any solutions? TIA!

Hey Jan:
I've seen quite a few posts in this regard with non-Apple mice and keyboard.
Well, the mouse and keyboard are quite old -- it could be that they're having a problem dealing with identifying themselves on the USB bus during sleep, or aren't identifying themselves fast enough at wake time. I'll just have to replace them I guess.
I've never seen a sleep resolution switching problem except on a VGA adapter to DVI connection to an old tube monitor.
Well, this is a pretty vanilla CRT monitor circa about 1999, so yeah -- it could once again be an age issue, and the fact that there is a DVI -> VGA adapter involved in the middle.
For worrying about fixing Mom's Mac, setup her remote VNC software (Apple Remote Desktop Client) and use the free Chicken of the VNC admin program.
I am quite familiar with VNC. As much admin as possible will be done by SSH, but I will have VNC in place before I leave. The big problem is going to be the fact that I'm going to be several timezones (and over 4000 km) away, so I won't necessarily be available at a moments notice to help her with this sort of thing.
The CRT issue we might just have to deal with by having her always run it at 800*600 (I don't think she'd really notice the difference, and as her eyes aren't what they once used to be, the slight size increase may be more confortable for her in the long run) until such time they she can afford to buy a nicer display (I did my duty as a son buying her the Mac mini and an iSight camera -- she has to take care of the rest ).

T400 - frozen mouse and keyboard after waking from standby

I'm experiencing a very annoying problem on my T400 with Win XP Professional SP3: around 75% of the time, when I wake up my T400 from standby mode, the mouse and keyboard don't work. Actually what happens is one of these situations:
1) Neither keyboard nor mouse (stick and pad) respond - Ctrl-Alt-Del to enter username/password is not registered, I can't log into Windows
2) Keyboard works (I can log into windows) but mouse doesn't respond
I have to close the laptop to standby and re-open, repeatedly, until it finally works. Though one interesting aspect is that if I have external USB keyboard and mouse plugged in, they always work.
Anyone have any ideas? Thank you in advance!

Hello jsolomin and welcome to community,

Mac Mini loses mouse on logout sometimes

We have a Mac Mini with multiple users. Seemingly randomly, but about once a day, when a user logs out, the mouse stops moving. The keyboard works, and I can remotely connect to it, but the mouse won't work again until I shut the machine down and power it back up.
I've reset the PRAM and the SMC, and tried swapping mice when it happens - nothing moves the cursor.
Weirdly enough, if I remotely login, and then go back to the Mini, I can see that the mouse's right button will work, but it won't still move and the left button does nothing. This is with 10.5.2 on a refurbished Intel Mini. I've tried memtest86; no errors were reported.
Any ideas? Will an archive and reinstall preserve the users?

I have the same problem with an Intel Mac Mini. Other users on another forum have experienced the same thing.
If the mouse is moved between logging out and the login screen appearing, the mouse is likely to be frozen. If you then log in using the keyboard only and log out again, the mouse will be unfrozen when the login screen reappears.
Users have reported the problem on a clean install of Leopard. Mine didn't have this problem on 10.4, but has done since the Leopard upgrade.
I've submitted a bug report for this problem.

Garageband Loses Connection With Keyboard After Sleep Mode

Whenever I open Garageband after my PowerBook G4 15" has been in sleep mode, my connection with my digital keyboard is lost (unable to record). I have to restart the computer in order to get the connection back. Any suggestions on what might be happening here and how to resolve this problem?
I noticed several other posts under "Internet Connections" where people are losing their internet connection after coming out of sleep mode (I am also experiencing this problem as well). Could these two problems be related? I never had either of these problems until recently. Could it have anything to do with recent Mac OSX software updates or iLife '08 updates?
Thanks. Rick.

have you tried simply unplugging and re-plugging-in the keyboard rather than a reboot?

Mouse and keyboard freezing

My computer has been running a bit slower lately, and I frequently lose mouse and keyboard control. Mostly happens after closing my laptop, and opening it again later. It will happen sometimes after disconnecting an audio interface while running Mainstage, or Logic Pro.
I run Adobe AE and Illustrator, and Logic Pro often. At first I was only having issues only when running two or more, but now it happens even when not using them.
I restart my computer about once a day because of these issues. Processes will continue normally, but I lose complete control.
I also am having problems with some of my adobe softwares, because of upgrading to Mavericks. I am thinking that I need to do a fresh install, and copy and past all of my documents, and picture files over, and reinstall all of my software. Thoughts?

Huawei e220 hangs on Mac Mini G4 and USB mouse and keyboard slow way down

I have a Mac Mini G4 running os10.5.8 My mouse and keyboard are a creative wireless combination that go to a USB hub then to the USB port on the mini. When I use my Huwei e220 wireless broadband modem, it frequently hangs when disconnecting, and the mouse and keyboard barely work. Activity monitor shows the CPU load is not very high at all, yet the mouse is almost stuck. If I put the computer to sleep, then it comes back and works fine. Its a bit of a hassle, and seems to be specific to the USB on the mac mini.

Is the modem connected via USB?

How do I hook a Mac Mini to an existing PC Laptop Dock in order to use existing 23" monitor, mouse, and keyboard?

My parents currently have a Dell Inspiron desktop (which thanks to Windows has crashed and requred re-installation of the OS and then ordering an OEM hard drive and starting from scratch). Anyway, my dad has started bringing home a work laptop, and I got him a laptop docking station so he could take advantage of the 23" monitor, keyboard, and wireless mouse that he prefers.
My brother and I are going to buy my parents at Mac Mini for Christmas. It's probably simple (or with my luck, impossible) but I need to know what I need to know in order to also hook up the Mac Mini to the monitor/keyboard/mouse (we may buy a keyboard and mouse). Is it just a matter of cables/splitters?
I'd appreciate any assistance. I've been trying to get my parents switched over to Mac for almost 10 years now. Dad is stubborn and will definitely want to use the 23" monitor he bought so I have to find a way to make that work. The keyboard and mouse aren't a huge deal - instead of being on the drawer that rolls out from under the desk, the Mac stuff can be on top of the desk. I just need to know if it's possible to avoid that and do everything through the docking station (even if I have to get a USB hub). I'm pretty sure the monitor has a DVI input, and the current work laptop is using the analog input.
Thanks all.

The Mac mini is not going to be able to use the Dell docking station itself, due to
the Mac mini is not a laptop
it does not have a docking connector
However you might be able to achieve what you want with a KVM (Keyboard, Video, and Mouse) switchbox which would sit between the dock and Mac mini and the Screen/Keyboard/Mouse.
For this to be as easy as possible, both computers need to be using the same types of connections, so that means USB for the keyboard and mouse, and ideally DVI for the monitor. I am using a dock with a Dell laptop and the dock does have a DVI connection as well as a VGA connection so yours might as well.
You would then need a KVM switchbox with USB and DVI connections. This one would be a suitable example http://www.amazon.com/TRENDnet-2-Port-Switch-Audio-TK-214i/dp/B004L62KN4/ref=sr_ 1_4?s=electronics&ie=UTF8&qid=1322228493&sr=1-4 you don't have to use the audio connections.
In theory you could use a VGA adaptor on the Mac mini to make both use VGA but widespread reports suggest VGA on the latest Mac mini is very unrealiable.

HT4938 New mac-mini server setup without keyboard and mouse

Im trying to use the server app to setup my new mac mini server without mouse and keyboard, but the server is not listed. I have tried using its IP address with no username and the serial number as password but it won't connect. Any ideas?

You may have a version mismatch. If I recall, setup assistant is OS version dependent so if the refurb is 10.5 and the Mac Pro is 10.6 you will likely not be able to use setup assistant.
However, just use ARD or Screen Sharing to connect. If the mini is visible on the network and in the ready for setup mode, you can ssh into the machine using the root user and the first 8 digits of the machine serial number. Then you can use the kickstart command to startup the ARD agent on the system. Use these commands while in the SSH session.
cd /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources
sudo ./kickstart -activate
sudo ./kickstart -configure -access -on -privs -all -users <shortname>
For now, the user will need to be root because there is no user. Then screen share the system to complete the remainder of the initial setup.
In theory this will work. Works on Xserves, so I believe the minis work the same for initial setup.
Hope this helps

Touchsmart 520-1047c Mouse and Keyboard will not work after sleep mode

I have an issue which I need some help with. When my computer goes to sleep the wireless mouse and keyboard will not work unless I restart, however each one will wake the system up but will not operate after that. I have tried just making the display go to sleep, both go to sleep but that makes no difference same issue occurs. The only work around I have found is going into the power settings and turning the sleep mode off for booth the computer and display. This does not solve the problem it just masks it. New batteries, unplugged and replugged the dongle, updated the bios and all drivers. Don't know what else to try. Anybody know how to fix this? Thank you in advance for your help.

Why do I sometimes suddenly lose Bluetooth from my Imac? I use it for my wireless mouse and keyboard. I then can't find it in system preferences but have to shutdown my Mac and hope it comes back

This is an infuriating problem and wondered if it happens to other people too and if I am doing the right thing by turning the Mac off then on again.

Wireless mouse and Keyboard Issue after closing the lid - external display

Can anyone give any insight. Recent purchase of a new Late 2008 15" MBP. I have connected it to an external 24" Apple monitor on my desk and use a wireless mouse and wireless keyboard on my desk top. I have configured the laptop to wake on bluetooth devices. So here is the problem: The laptop when the lid is up recognizes the bluetooth keyboard and mouse. I close the lid/screen. Laptop powers down... the after several seconds I move the mouse and the laptop comes alive... But after that there are no bluetooth devices attached. When I use the mouse, I get "connection lost" with a white figure of the mighty mouse on the screen. The wireless keyboard is not there and I have to open the lid and manually find the mouse and reconnect. The keyboard seems to work however....
Apple..... any thoughts..... anyone?????

Hi Stentdoc; I'm thinking, 'connection lost ~= sorta low AA batteries in the Mighty Mouse? (I would put in fresh AA batteries in the mouse and keyboard, to eliminate as an issue that the 'connection lost' is due to low batt voltage; that this is causing the failure to wake.) ... then, in System Preferences > Hardware > Energy Saver, settings for Power Adapter > Sleep, set to "never" for "Put the computer to sleep when it is inactive for ..." to eliminate that as a conflict when trying to wake with bluetooth from sleep induced by closing the lid ...
Check your current "Sleep" setup (I left my MBP as "3")
go to Utilities > Terminal
After you launch Terminal, the first step is to determine which sleep mode your Mac is currently using. You can both view and change the sleep mode using the Unix program pmset. To see your current settings, type (or, copy and paste)
pmset -g | grep hibernatemode
press 'enter'
You should see something like this:
$ pmset -g | grep hibernatemode
hibernatemode 3
So your machine is using mode 3 ... thanks to the documentation for the handy Deep Sleep Dashboard widget, which puts your machine immediately into hibernation mode (so you don’t have to yank all the power sources to invoke it):
* 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
* 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
* 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
also, I enabled this (to change back, input "lidwake 1":
go to Utilities > Terminal
type in sudo pmset lidwake 0 then "enter"
it will ask for your password. type it in, that's it!
Now, when your computer is sleeping with the lid closed, when you open the lid nothing happens until you press any key ... nice: keeps it off when accidentally opened, like in a backpack?
WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.
To proceed, enter your password, or type Ctrl-C to abort.

How do i run an external monitor with my macbook and change settings so that when i close the lid the signal to the monitor is not lost and i can continue using the mac with a mouse and a wireless keyboard?

No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.

Brand new IMac 27 bluetooth mouse and keyboard not connecting for eight minutes after start up.

I have a new imac 27 that has worked flawlessly for three weeks.
All of a sudden, when starting up the mac boots fine but the bluetooth mouse and keyboard are non responsive. This state is maintained for between 7 and 8 minutes then both mouse and keyboard start working and continue doing so for the rest of the day....until the next restart and the whole saga repeats itself.
Both sets of batteries are fully charged.
I have scoured different sites and tried any suggestion that made any sense, to no avail. All I am able to do at the moment is to do the time, wait the 7 to 8 mins. and then all's good.
My first Mac and this is very annoying especially as Apple must be aware of this issue but no solution is forthcoming!
Any suggestions/workarounds would be great.
Thanks

if you are using rechargeable batteries sometimes they don't stay charged for as long as they should try using alkalaine batteries and see if the issue still persists.
also try doing an SMC reset, the following article tells how to do this:

TS3048 I am usng a bluetooth keyboard with my Mac and some of the keys are not working. They are the numbers 1 through 9. I have gone through the troubleshooting for mouse and keyboard and everything looks good. How can I get them to work again?

Hi, I am using a Mac computer that my husband set up. I have worked on it recently with no problems. Today, I am having problems with the bluetooth keyboard not working properly. The numbers 1 through 9 do not work. I have gone through troubleshooting wireless mouse and keyboard issues and everything looks good. Except, when I check the keys on the keyboard viewer, these keys still do not work. The webpage guides me through and at this point I do not know what to do next, because the keyboard is still not working properly. I sure hope there are some experienced people in the community to help me. What should I do?

Hi:
I wish my suggestion had gotten you further.
I do suggest you try to connect the keyboard again. The request for a number is a step in it trying to pair. If it gets by the number, it sometimes takes a little while to get connected. If you are unable to get it connected and want a new one, I have been using Apple Bluetooth keyboards for years - and I like them. The one I have (the newest model) only uses two batteries and is very thin.
Speaking of batteries, if you are not already doing so, you might consider rechargeables. I have a drawer full of them and use a 15 minute charger. I go tired of buying batteries and rechargeables are environmentally friendly to boot. At the moment, I use 2450 mAh Energizers and a 15 minute Energizer charger (all purchased new on eBay at a very reasonable price).
I am far from an iPad "expert," although I have one. If my suggestion below does not help, post your question in a separate thread in the iPad forum.
I had a terrible time syncing my iCal on my Mac with my iPad iCal (confusing - hopefully it makes sense). I quit using iCloud as that added to the confusion. There is a facility to one-time sync items. When you connect your computer to your iPad, iTunes opens. The system begins a process (automatic backup and so on). After it finishes, you can click on "info." At the bottom of the screen, there is an advanced section. You can select any of the items and then force it to sync. The iCal information from your computer would be deposited on the iPad.
After all that, I do not use a Google calendar so the information may be worthless to you.
If you want to reset the iPad to factory settings, you can do that when it is connected to iTunes (one of the options). Me being me, I try never to erase anything.
