T500 shuts down on its own after system update
Hello all,
I have recently ran System Update to update some of the drivers and utilities on my T500.
After the update I suddenly noticed 2 extremely troubling side effects:
1. (this is the least troubling) I Lost all the indication for the function key operation (e.g.. Volume control, brightness control, etc...). The function keys seem to work but there is no on-screen indication
2. (and this is the most troubling) I noticed aafter leaving my computer on for a while (and leave the room) I would come back to find it turned off.
this happened in intervals of 15-120 min.
I checked the power options but everything seems to be as it was (my machine is set to "always on" regardless of power connection and I also turn off the hibernation option).
I even un-installed the lenovo power manager (it was one of the updated features) but that didn't help.
These are the items that I updated:
system migration assistant 6
ThinkPad video features (AMD switchable Graphics(M8x)) for windows 7(32/64bit)
synaptics ultranav driver for win xp, vista and win7 - WW-
ThinkPad power manager (i uninstalled this one already- no change)
ThinkVantage access connection for windows 7
Thinkpad hotkey features integration package setup
WIFI Driver for Intel cards (for windows 7 64bit)
If anyone here ever encountered such problem or knows what is causing my machine to turn itself off every once in a while I would appreciate a tip!!!
I am running windows 7 64bit and I have TPfan control installed.
Thank you all so much!!
I must say, also, that examining the list of updates in my first post, my biggest suspects are (in order of prominence):
ThinkPad video features (AMD switchable Graphics(M8x)) for windows 7(32/64bit) - this can explain the heating as well as the disappearance of the OnScreen display BUT i tried starting the computer the other day with the onboard graphic adapter and the computer still crashed. puzzling...
ThinkPad power manager- as i mentioned before, i uninstalled this one already and there was no change but it might have screwed up the definitions somewhere because the computer was (beside all other symptoms) going into sleep mode despite the fact that it was set up as "always on" and "never sleep".
WIFI Driver for Intel cards (for windows 7 64bit) - that might be a long shot but its the one thing that is always running in the background.
does this make sense?
do you have different suspects?
I am trying to share as much of my conclusions here as possible. i hope this helps.
thanks again!

Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
This happened a couple of months ago, unplugged everything and it restarted, now that won't work.Hi BDAqua,
I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled. I have moved 20 GB to an external hard drive, as I only had 10% open space.
I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
I will wait to here back as to your suggestion regarding the Tech Tool check
Thanks for all your help.
Gratefully,

Mac Pro shut down on its own, then on boot up it beeped steadily for 2 min?
I put my 2009 Mac Pro to sleep then the next day I find it completely shut down! I boot it up and then I hear a steady beep (every second) for about 2 minutes. After 2 minutes the beeping went away.
Any idea what caused Mac Pro to shut down on its own? And what does the steady beeping mean? The beeping is coming from inside the Mac Pro's speakers, not from my BOSE 5 computer speakers.
I don't think there was a power outage as the UPS is fully charged, and I asked a neighbor across the street.I wasn't clear in my description, it's a steady continuous beep, it's a rhythmic beep -- it'll do this for 200 beeps or about 2-4 minutes.

Macbook Pro 2010 upgraded from Mavericks to Yosemite keeps shutting down on its own
I upgraded to OS X Yosemite about a month ago, I have a macbook pro 2010, and in the last two weeks it started shutting down on its own. At first when i'd wake it, the fan would come on loudly and then it would shut down. In the last couple of days, I would make sure all programs were shut when it wasn't in use and then put it to sleep but every time i'd return it would be shut down and need a hard restart. If i just pressed the on button lightly it wouldn't start. And when i turn it on the fan comes on immediately. I'm a publisher so I'm working in indesign and illustrator a lot but I keep a constant look out for my memory and this isn't the problem. I'm working to a deadline here and can't afford to lose my computer for 3 days in the mac store (I live in Barbados) to get it fixed. Any advise?

Seems like mail is shutting down on its own several times a day. Any one have this problem
Other people have had the same problem. See this thread:
https://discussions.apple.com/message/17337738#17337738
Be sure to quit Mail before moving or deleting any Mail-related Library files!
I'd also advise having a recent backup before moving/deleting any Library files.
As you may know, your user Library is hidden. To see it: in the Finder, hold down the Option key and, under the Go menu, choose Library.
Note that the advice in that thread is from OS X 10.5. Things are in different places now, plus you probably have more than one file called Envelope Index (with different suffixes).
Your Envelope Indexes are now in YourUserLibrary/Mail/V2/MailData
Mail's caches are now in YourUserLibrary/Containers/com.apple.mail/Data/Library/Caches
You might want to try either the Envelope Indexes or caches first, not both at the same time, in case the problem is only with one.
If you do as advised in that thread, Mail will re-create your Envelope Indexes and/or caches (you'll have to "import" all your messages, which is just Envelope Index re-creating its index). If all works well after that, you can then remove the old caches and/or Envelope Indexes.
Please let me know.... -
MacBook Pro won't boot and shut down on its own.
Hi, I am running a Macbook Pro. My problem is that the OS froze during use, and I could not move the cursor. As which point I force shut down by holding the powerswitch. From that point onwards I could not get the machine to boot, it keep getting stuck at the grey screen with Apple icon. After loading at the grey screen for 15-20 mins it shuts down on its own.
I've tried to reset SMC (shift-control-option + power button) and PRAM (Command-Option-P-R) but it dint work. Please help. Thanks.It appears your problem occured after you upgraded to 10.8.2, but if you did it right after the SSD and RAM switch then it's hard to tell exactly what is causing the issue.
I advise returning back to factory, hold command option r boot and wipe everything and reinstall 10.8
..Step by Step to fix your Mac
If the problem continues, then make a warranty/AppleCare call, hopefully you didn't strip the screw heads or leave any other tell tale damage inside.
If your fine on 10.8.2 for some time, then switch the RAM and do a hardware test extended or Rember or Memtest to make sure the new RAM is not the issue.
If that's fine then Carbon Copy Cloner to the external SSD and hold option key down to boot from it and test that.
Then do the internal SSD switch and test that.
Take your time, Mac's are so finicky and you can't just slap this or that and expect it all to immediatly work like it should. -
I'm currently working in Myanmar and no chance to going into a Mac service provider or store. I was using my Macbook Pro (mid 2010) when beer was spilled onto the table. I lifted the computer instantly and as i did not see liquid on the machine and also it had a protective cover i was sure no liquid got in. I removed the cover and it was dry but then 5 minutes later it shut down on its own and it would not turn back on or charge. I left it for an hour or so and then it turned back on and was charging but then since i thought that may be it was because some liquid got in, I turned it off again immediately and disconnected from power source.
what is the best way to proceed knowing i won't be able to bring it in to a technician anytime soon?without on hand diagnostics, nobody can tell you the correct answer on that. No.
5 minutes later it shut down on its own and it would not turn back on or charge.
bad news
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. -
My PowerBook shuts down on its own (persists when RAM is changed)
Hi all,
My PowerBook shuts down on its own. It will display the "Are you sure you want to shut down your computer now?", and even with me clicking Cancel, it will just shut off immediately after displaying the sign, as if I pressed and held the Power Button.
I've sinced change the RAM back to the default piece, but the problem persists.
Moreover it's a random, although frequent and frustrating, occurance, so I'm not sure if the service centre will take it in since I cannot reproduce the problem.
I'm using it on a 1920x1200 display.http://docs.info.apple.com/article.html?artnum=14449
first you can try resetting Power Manager.
the rpoblem may be caused by some software bug, try making new user, then log in as new user and work for a while - if it works ok it's something in the original user software.
then you can try "archive and install" of the OS.
also, problem maybe caused by bad keyboard, top case (where the power button is) or logic board.
anyways keep files backed up and maybe get it diagnosed by service shop. -
HP pavilion dv6000t shuts down on its own
Hello,
My HP Pavilion dv6000t is now 3 years old and I recently replaced the fan as it was making a lot of noise. Referring the online guide, i removed all components necessary to replace the fan and put it back. It worked great for a few months and now I started getting blue screen of death and the laptop shuts down on its own. I then tried starting it back and it works for like 15 mins and then shuts down on its own. Found that hard disk gets very hot. Initially thought it might be an hdd issue. Got another 2.5" laptop harddrive, inserted it and started installing windows. It behaved the same way. During formatting of hdd, the screen went blue completely and then the system shut itself down. Switched back to old hard disk, installed fedora linux and it installed fine. As soon as it installed, logged into the OS and it showed error that one of the hard disks is failing with bad sectors. Worked with the OS for atleast for like 1 or 2 hours with basic navigation, browsing and then again in linux it went to full colored screen and then the system shut itself down. I touched the section to the left of the touchpad and it was warm. Tried installing windows again using the recovery CD but it crashed out in 10 mins and system shut itself down. Dont know what next to replace. Replacing mother board wont make sense as its as good as buying a new laptop itself. Any inputs is appreciated.
Thanks.
BrijeshHi, BrijeshGawande
Have you tried running the hardware diagnostics from the BIOS? Multiple failing hard drives sounds like it could be a bad SATA controller.

My iPad air keeps shutting down on its own!
My iPad air keeps shutting down on its own, and this is the second IPad Air doing this. I really don't want to go trade it in for another. Does anyone have the same issue and is there a way to fix it? And yes I've done the manual reset and computer reset.
Memory Size & The Impact of 64-bit Applications
The iPad Air, like the iPhone 5s, ships with 1GB of LPDDR3 memory. Apple frowns upon dissection of review samples but I think it’s a safe bet that we’re not talking about a PoP (Package-on-Package) configuration but rather discrete, external DRAM here. It’s also probably a safe bet that even the iPad mini with Retina Display will ship with 1GB of memory as well.
Something I didn’t have time to address in my iPhone 5s review was the impact of 64-bit applications on memory usage. I actually ran some tests after the 5s review hit but never got the chance to share the data, so I figured now is as good a time as any to do just that.
Unlike traditional desktop OSes, iOS doesn’t support paging to disk (or in this case, NAND). Application data can either reside in memory or the associated process is terminated and has to be reloaded the next time you request it. It’s a decision likely made to both maintain user experience and limit the number of program/erase cycles on the internal NAND.
The good news is that iOS was architected to run on as little hardware as possible and as a result tends to be quite memory efficient. There are also power implications of going to larger memories. The combination of these two things has kept Apple on the conservative side of increasing memory capacity on many iDevices.
The move to a 64-bit platform however does complicate things a bit. Moving to a larger memory address space increases the size of pointers, which in turn can increase the footprint of 64-bit applications compared to their 32-bit counterparts. So although there’s clearly a performance uplift from app developers recompiling in 64-bit mode (more registers, access to new instructions), there’s also an associated memory footprint penalty. Since the iPad Air and iPhone 5s don’t feature a corresponding increase in memory capacity, I wondered if this might be a problem going forward.
To find out I monitored total platform memory usage in a couple of scenarios. Before measuring I always manually quit all open apps and performed a hard reset on the device. Note that the data below is reporting both clean and dirty memory, so it’s possible that some of the memory space could be recovered in the event that another process needed it. I hoped to minimize the impact by always working on a cleanly reset platform and only testing one app at a time.
I looked at memory usage under the following scenarios:
1) A clean boot with no additional apps open
2) Running Mobile Safari with 4 tabs open (two AnandTech.com tabs, two Apple.com tabs, all showing the same content)
3) Infinity Blade 3 (64-bit enabled) sitting at the very first scene once you start the game
4) iOS Maps in hybrid view with 3D mode enabled, with a WiFi assisted GPS lock on my physical location
5) Google Maps in the same view, under the same conditions. I threw in this one to have a 32-bit app reference point.
In general you’re looking at a 20 - 30% increase in memory footprint when dealing with an all 64-bit environment. At worst, the device’s total memory usage never exceeded 60% of what ships with the platform but these are admittedly fairly light use cases. With more apps open, including some doing work in the background, I do see relatively aggressive eviction of apps from memory. The most visible case is when Safari tabs have to be reloaded upon switching to them. Applications being evicted from memory don’t tend to be a huge problem since the A7 can reload them quickly.
The tricky part is you don’t really need all that much more memory. Unfortunately as with any dual-channel memory architecture, you’re fairly limited in how you can increase memory capacity and still get peak performance. Apple’s only move here would be to go to 2GB, which understandably comes with both power and financial costs. The former is a bigger concern for the iPhone 5s, but on the iPad Air I would’ve expected a transition sooner rather than later. -
HP officejet pro 8600 Plus shuts down on its own while making numerous copies.
My printer HP officejet Pro 8600 Plus keeps shutting down if I print or make more than 5 copies then gives me a message to avoid damage shut down the printer with the on button. Well it shuts down on its own.
Hello mb_bernhardt,
Welcome to the HP Support forums. I understand that your Officejet Pro 8600 Plus printer is giving you a Printer Failure message and then the printer shuts down.
I’ve included the A 'Printer Failure' Message That Might Include an '0x610000f6' or '0x61xxxxxx' Error Code Displays o... document. If the error message that you’ve received includes an Error code there is one set of instructions to follow, and if there is no Error code there is another set of instructions to follow.

my iPad shut down on its own and when i switched it on, it asks to 'Activate iPad' and reads below 'This iPad was lost and erased. Sign in with the Apple ID that was used to erase this iPad". Please help!!!!
Is it possible that you or someone who knows your iCloud sign on went into the Find My iPhone app and erased your device via iCloud? Because that is what that message is saying.
Have you tried to sign on with your Apple ID and password?
