HP Envy 14 (2020NR) - randomly missed keystrokes after wake from sleep (on battery power only)

While running on battery power, sometimes when I wake from sleep, keystrokes will randomly be missed. It doesn't always happen, and I need to do more experimentation to figure out just how often it occurs. To fix it, I just reboot the computer (while still on battery power), and the problem seems to be gone. It can also be fixed by simply plugging in to A/C power. I am using Windows 7 Home Premium 64-bit.
I have seen similar threads where people say that repeated keystrokes are missed, or rapid keystrokes are missed -- but so far those threads have remained unanswered, and my problem seems a little different in that no one else has mentioned a correlation with running on battery power. The problem never occurs otherwise, for me.

If you are still under warranty you need to return the laptop for service. If not I am afraid it is a motherboard issue requiring replacement. You have done all the diagnostics a professional would do. The fact that the battery works in another computer tells us it is not the battery.

How do I fix missing icons after wake from sleep?

This issue will not go away and continues as a significant bug in Mountain Lion 10.8.2.
If I let the battery drain beyond 5% and put it to sleep. Or if it goes into hibernation automatically due to low battery power. Imust push the power button to wake it.
It then shows the progress bar to gather the data and starts back up normally. Except that now icons in the bar area show artifacts, and native Apple top screen menu item icons such as bluetooth and Wi-Fi no longer show after a full shut down and/or restart.
What's worse is that all Mail, Safari, Text Edit and other native applications loose normally visible icons displaying blank boxes where they would normally show.
Running Disk Utility and Disk Warrior does not correct the problem. And starting up in Safe Mode has no effect. An Apple store unchecked the automatic graphics switching. But that does not work to solve the problem.
Today, the Finder would not launch on restart and had to be launched manually each time after a restart.
An SMC or PRAM process also do not fix the problem.
I also deleted all cashes and rebuilt launch services running Onyx. It doesn't fix the problem either. The last thing I did was reinstall 10.8.2 from a flash drive installer. Still no joy.
Has anyone found a better way to fix this problem without going through the tedious system restore?

For the Downloads icon. From your Safari menu bar click View > Customize Toolbar.
Drag up the default toolbar.
You need the folder for the Mountain Lion installer in the Dock.

BUG: Sandisk USB flash drive in "half-mounted" state after wake from sleep

My Sandisk Cruzer Crossfire 4GB Flash Drive is left in a half-mounted state after wake from sleep. The Finder believes the drive is still mounted, the icon is on the Desktop. However opening a file on the drive, or trying to eject the drive, results in a long beach ball, followed by a message that I removed the drive without Ejecting it first. The same drive continues to work fine on my Tiger machine, and on PCs.
Bug Report:
Setup:
Macbook 1st Gen (2.0 Ghz)
Mac OS X Leopard 10.5 Clean Install
Sandisk Cruzer Crossfire 4GB USB Flash Drive (in either port)
Repro:
Plug in the drive.
Close the MacBook to put it to sleep
Reopen the MacBook
Result:
The lights on the flash drive never light back up after wake from sleep. Navigating the drive, or trying to eject it results in a "you removed the device without ejecting it first" message.
Expected:
Drive should still be mounted and accessible after waking back up.

It may be a design flaw in the device. Mac OS X does a lot more power management than most other OSes, including tearing devices down to little or no power during sleep. It is possible that the device simply misbehaves due to corrupted memory state or reports a substantially different GUID or something similarly bizarre upon wake. (Okay, that last one wouldn't technically be a power management issue....)
If it doesn't have any problems except when sleeping the system, I would just make sure I unmounted it before putting the machine to sleep and wouldn't worry about it. Maybe check with Sandisk to see if they have a firmware updater for the device.

Left USB-Port dead after wake from sleep. Just restart helps.

I hoped Apples keyboard-Update today would solve my biggest hate-bug in this buggy POS called Leopard. It didn't.
As usual on my Leopard-Macbook Pro, no device will work on the left USB-Port after I waked the computer from sleep. Just a restart helps. I hoped this update to solve this, because it replaced among others "IOUSBFamily.kext".
Terminal gives a timeout error for the internal USB-Hub after wake from sleep. I assumed this should be related.
I'm really angry now.
When will Apple solve the most urgent problems in Leopard?
Was 10.5.1 just smoke and mirrors to make (fool people into...) people upgrade who intended to wait until the first maintenance-update?
Was Leopard Apples attempt to make Windows-Users more comfortable by putting in some heavy extra-bugs and blue screens?
FIX IT FINALLY! And f... don't wait for Macworld to release 10.5.2. It's desperately needed and the current state of Leopard will leave some people very sad at christmas after getting their first Mac. First impression counts and many more peoples first contact with the Mac will be at christmas...

Apple knows the problem and for some reason they are stumped on fixing it. this is so bad I can't believe it. On my macbook pro with Leopard installed, USB left port is dead after sleep. Only restarting can power it back up. I have to restart every day to use my external hard drive for time machine or when putting my flash drive in the port.
Come on already Apple. This is a SERIOUS, SERIOUS problem.
Fix it.

External monitor flashes on and off randomly after wake from sleep

I have a Mid-2009 13" MacBook Pro 2.26GHz hooked up to a Samsung SyncMaster 2033 External monitor via the MiniDisplayPort-DVI connector.
After waking from sleep, the external monitor will go blank for a fraction of a second at random intervals (display on the MBP remains normal). The flickering clusters are about minutes apart, while flickers within a cluster (usually 2-3 flickers per cluster) is of order seconds apart. "Detect displays" will not make this go away. The only way I can make it go back to normal is to unplug-and re-plug the MiniDisplayPort connector on the MBP.
Anyone else got a more elegant solution to this that does not involved wearing down the displayport?

I tried this. No change. However, I did start playing with the Display settings. Oddly enough, when I change the disfunctioning monitor to 720p it starts working again. Does this mean anything to anyone?

10.9.4 update causing internet browsing errors after wake from sleep

Macbook Pro Late 2011, OS X 10.9.4
So before the 10.9.4 update, I had no problems with Wifi and wake from sleep.
Now, after the update, random web pages either don't load (Chrome & Firefox) or return a "Memory Not Allocated" error (Safari). Also, my Work VPN application stops being able to connect. The related Console error is:
acvpnagent[104]: Function: getInterfaces File: ../../vpn/Common/Utility/NetInterface_unix.cpp Line: 1277 missing PPP destination address for interface "utun0"
The only solution I've found is restarting.
Any ideas?

Remove the Cisco VPN client. Use the built-in client, if possible.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and (unless otherwise specified in this comment) I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Bluetooth Unresponsive After Wake from Sleep

I have an issue where when my macbook pro wakes from sleep, the bluetooth mouse will not connect, and BT becomes unresponsive. Sometimes I can turn bluetooth off then back on and be OK, BUT 95% of the time, I have to restart the computer to get bluetooth back.
After waking, the BT appears to be on, I get the popup on the screen which tells me "connection lost" with a picture of a mouse. I can open BT preferences and turn BT off, but nothing happens. I can even recheck "on" but it is completely unresponsive.
Things tried:
Allow BT to wake this computer is UNCHECKED
in activity monitor I have forced quit BLUED, but BT does not come back.
I have trashed the BT preference file Mac HD/library/preferences/com.apple.bluetooth.plist
I have reset SMC and PRAM
Tried a Logitech V470 and mighty mouse
Fresh install of 10.6.0, then upgraded to 10.6.1, then 10.6.2 (using combo)
Tried disabling steermouse, fresh batteries, holding my mouth right...
When the BT is not responding, the BT name either changes to 2.2.4f3 (which is the Apple BT software version), or it says "name not available".
Also in system profiler, when BT is not responding the BT "Hardware settings" section is missing. It starts with "services".
This is driving me crazy. Could this be hardware related? I feel it is more software, since on restart, the BT mice pair perfectly and work great. The never randomly disconnect.
This issue only happens when the computer resumes/wakes from sleep.
Everyone please provide feedback. I am the only one with this issue? I have scoured the net, and find very little regarding this exact issue. I am within my 90 days from buying, should I call Applecare or is it a waste of my time?
Thanks for your help,
Jeff
Spec's:
mid-2009 aluminum uni-body, Intel 2.66Ghz, 4GB Ram, 320GB HD
Snow Leopard 10.6.2 (Clean install to 10.6, then upgraded)
Login items: Steermouse, PleaseSleep, and Windows Live Sync
Also running at startup, but not in Login items: Paragon NTFS, Flip4Mac,
MacFuse, LogMeIn

I've got what sounds like the same problem with my new unibody MacBook Pro.
I've had the problem with both 10.6.1 and 10.6.2.
I also find that a reboot fixes things. In my case, I can sleep/wake multiple times with
no problem, but once the BT goes unresponsive upon wake, every subsequent sleep/wake
will suffer the problem until I next reboot.
I also discovered that in my case I can re-pair the non-responsive devices (two flavors
of Logitech mice and an Apple wireless keyboard) while in sick-BT mode and they will
work until I next sleep/wake, whereupon they will again fail to connect and my
choice is either to re-pair yet again, or reboot and have the problem go away, at least
for awhile.
I'm trying to correlate my activity with my BT going out to lunch, but have yet to narrow
it down definitively. I have one or two data points that make me suspect it goes south
after I use VMware Fusion (Version 2), but I cannot yet rule that one completely in or out.

Crashes after wake from Sleep after 10.8.1 update

2.5 Ghz Mac Mini (mid 2011), 8 Gigs of RAM
Since the day I upgraded to 10.8.1 I have had persistent crashes, 1 every 24 hours or so. It's always shortly after a wake from sleep. In all cases, it is impossible to switch to a random open application. But once I hit that application, no other application will respond to anything, including a Force Quit, or if it will force quit, it won't relaunch. A shut down will hang because an app refuses to quit. I can quit the Finder, but it won't relaunch. Have reinstalled Mountain Lion twice, zapped the PRAM, reset the SMC, checked and extensively tested the HD and RAM. Replaced RAM with original Apple RAM. Didn't help, so I swapped back to the RAM from Crucial. I can't think of anything else to try. Machine does not crash unless it has been asleep. Runs flawlessly when sleep is disabled. After a reboot (usually via a shut down via the power switch, start from scratch, check of the HD integrity, and then a clean restart) the machine will run fine, sleep and wake normally for about 24 hours. As near as I can tell from the logs, the hangs usually begin right after the Time Machine Backup after a wake from sleep finishes. If I don't allow the machine to sleep, there are no problems of any kind. Making me crazy. Did not occur under Lion or the .0 version of Mountain Lion. Is making me crazier than I normally am which is sorta serious.

Any solutions to this problem? I too have this kernel panic, however it only happens about once a week. Always upon wake from sleep as you've indicated.
FYI I don't have intego software, or an APC installed. Nor am I using filevault.
This is on an up to date, MacBook Pro Retina.

10.5.2 Update - Second monitor "blinks" after wake from sleep

Posting in the off chance that others have seen this behavior. This seems to be Leopard related, and did not start happening until after I installed the 10.5.2 update.
After waking from sleep my second monitor will blink on and off for anywhere from 2 seconds to about 30 seconds at which time it functions properly. It does not do this on initial startup OR when booting from my tiger volume (backed up with superDuper before a clean install of Leopard). Unplugging the display and plugging it back in also stops the "blinking"; turning the monitor off and then on has no effect.
My machine is a early (2007) model 2x2.66 dual-core with 3GB of (Apple) RAM and a GeForce 7300 GT. All firmware updates have been applied and software update reports no updates available.
The displays are both Sceptre X9G-NagaV 19" flat-panels connected via DVI, though I see the same behavior when using my 20" apple cinema display as second head. (I know these are cheap monitors. Please refrain from telling me that the displays are at fault - it 's not a problem with the display, as this doesn't happen under Tiger. The monitors have performed admirably for over two years)

Have you tried unplugging the second monitor, rebooting and letting it run without it for a little while, and then plugging it back in to see if it clears some persistent loading problem? My monitor has always gone out on me kinda randomly, but I think it's my GPU in my PMG5 that's losing power and resetting or something so it wouldnt be the same issue (I've gone through two so far with the same results).
Alternatively, try changing some of the display settings, such as resolution, color, and such to see if the change corrects how it's loading the display.

After Lion upgrade, having network issues after wake from sleep

After upgrading to Lion from 10.6.8 on my MacBook Pro (15-inch, Early 2011), I am unable to connect to the Internet after the computer wakes from sleep. I should rephrase this - I am able to ping IP's and DNS (DNS servers are present) however none of my apps will connect (Safari, iChat, etc) -> they all indicate the Internet is unavailable. I have two Airport Express's running 7.5.2 extending a WiFi network off an Airport Extreme running 7.5.2. This issue is specific to waking from sleep. Any thoughts or suggestions would be appriciated.

It's definitely linked to Time Machine and backups.
I think If I put my machine to sleep/close the lid and Time Machine happens to be performing a backup, when I open the lid again, the network connection is lost and I receive a bunch of errors about the backup disk being unavailable.
This means that if my mbp isn't in the middle of a backup when I put it to sleep, wifi comes back up without a problem.

Bluetooth devices lagging after wake from sleep sometimes.

I have the Apple bluetooth keyboard, magic mouse, and magic trackpad. All batteries are charged and I have tried others by the way. This issue only happens sometimes, as it has happened before, but stopped for a few months, and now happened again tonight. What is happening is that my laptop (macbook late 2009 with mac os x 10.7.2) wakes from sleep (all default energy saver settings set and I am able to wake the macbook with any of the bluetooth devices), and my bluetooth devices mentioned above are laggy for about 15-45 seconds. What i mean by laggy is that when moving the mouse across the desk after the login screen is already fully loaded, it jumps and is clearly not tracking like it usually does. The bluetooth trackpad and keyboard experience this same issue.
Now the thing that leads me to believe it's bluetooth or software is that my macbook's built in keyboard and trackpad do not lag and function correctly as soon as the computer is woken from sleep and prompts me with my login screen. This also leads me to assume that it's not my computer running slowly or having too many processes or not enough memory. This problem happens even if I have no programs running (other than OS X's default processes). I have taken my macbook into the Apple genius bar thinking it was a bluetooth hardware issue, but they ran checks and confirmed that it was not and obciously, we could not get the issue to reproduce their at that time. I would love to hear from anyone who has experiecned this before, or is currently. We need to get Apple's attention with this issue because they have not listened to me when I submit a feekback form. This has been happening since 10.7.0 by the way. Thanks and happy holidays.

Connection Lost After Wake From Sleep

I am using a Macbook Pro and Linksys WRT150N W/L router. Every time my MBP wakes from sleep, I lose my internet connection. My menu bar still shows that I'm connected to the network, but I lose all connectivity. I cannot connect to internet or my router settings unless I do a complete restart. Network preferences shows connected to network but no connection to my router IP address under TCP/IP tab in the advanced settings. I also have a drop out of signal a few times an hour. My iMac DV does not experience the drop outs or connection loss at anytime. I have reset my router numerous times and used default factory settings all with the same results. Does anyone have an idea what the problem may be? Thanks.

I was always experiencing drop outs as far as what my signal was showing in my menu bar. It would drop out even if I was on top of my router. I had upgraded to 10.4.11 and the day after I did that, the problems started. I thought I might as well upgrade to 10.5 to see if that might help it. I think the 10.4.11 had done something to my W/L card and upgrading to 10.5 wouldn't have helped it unless I upgraded from 10.4.10 to 10.5, skipping 10.4.11 all together. I'm gonna bring my router and MBP into the genius bar and see what they can tell me about. Thanks for replying. I'm glad and sad to hear that I'm not the only one experiencing these symptoms.

No IPv6 after wake from sleep

Hello,
     When my MB pro wakes from sleep there is no IPv6 connectivity. In order to restore IPv6 I need to stop/start the Thunderbolt Ethernet adapter (make service inactive/make service active) or reboot.
     Details on my configuration:
     OS X 10.9.2
     Thunderbolt Ethernet Adapter used for network connectivity (Wi-Fi OFF)
     Native IPv6 network (not tunneled)
     IPv6 and v4 manual config (no DHCP or SLAAC)
     Dual stack TCP/IP configuration
     IPv4 works
     IPv6 works until MB goes into sleep mode

^--- Boo
This causes problems for IPv4 as well because apps like Firefox and Safari try using the IPv6 DNS servers and give up before falling back to the IPv4 servers. So this problem breaks more than IPv6.
Is this a bug or do I have something misconfigured?
Thanks.
                               --Tom

I see this (sort of) behaviour as well. When I look into the tcp/ip tab of the network (system prefs) I see
fe80::1:1 as router, that is why v6 stops working. After turning v6 off and on again the correct router IP appears.
NB. this is on wifi
