Have any T430x users had random shutdown problems?

like this one with the T400x model:
T400s random shutdowns - Lenovo Community
If not I'll buy a new one, otherwise I'll buy another brand. Thanks!

Have you run all the newest updates at the new Lenovo update site. It is up and running and took my computer a while to update including a new bios.
This helps but will/can make it worst for a while.
My Take:
If you laptop is new OR you have just installed a good bit of software OR did anything to move alot of files around on your drive it will take time for Vista to re index the files. Being that the processor is slow it will suck up resources that are required for the touchpad or even the keyboard. Mine would even freeze the keyboard and you could type and nothing would happen and then all of a sudden everything you typed pops up on the screen.
I have found that when ever you "upset" the indexing it is best to just leave your computer alone and let it do it's thing. You will see alot of hard drive and processor activity. After this stops, all is well and you should not have any more problems.
This is my opinion on what is happening and I have noticed the same on all three of my X301 units one with normal hard drive and one with 80gb SSD and 128gb SSD. Basically the slower processor is fine 90% of the time but seems to bog down a bit when asked to do too much.
Try this and see. Leave you laptop up and running for several hours, make sure it is set to not go to sleep and come back and see if it does not make a difference.

Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7

Hello,
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.

G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

Thanks for the advice. I did check the system.log in Console and found the following altert:
PMU FORCED SHUTDOWN, CAUSE = -122
Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
• PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
• OS 10.4.7
• Logging in with Open Directory/Active Directory mobile profiles
• iTunes 7
Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
(And Apple wants to be taken seriously in the enterprise market?)

Random Shutdown Problem Fixed (for now)

I experienced the same random shutdown problems/symptoms with my MacBook that have been extensively described in this forum and elsewhere. I sent it back for repair under AppleCare and it was returned in 3 days. It has been running now for 4 days with no problems and far cooler and quieter (the fan rarely comes on) than it was before. The repair sheet indicates that the heat sink and heat assembly unit were replaced.
I'll keep my fingers crossed, but at least in my case and perhaps others, the problem may simply have to do with the thermal contact with the heat sink going bad and the processor simply shuts down due to overheating.
MacBook 2 GHz Mac OS X (10.4.7)

Followup:
They told me something interesting at my Mac Retailer. They have had two other machines brought in doing the same thing. They tried new logic boards with no success, they tried new thermal assemblies with no luck, new ram - nothing seemed to solve the problem.
What they finnally did was replace the Hard Drive - they tell me this has fixed the problem. Now I don't know if that is what they'll do to mine. The other two machines had the 60gb drives - mine is a 100gb, but we'll see. From all I have heard, this doesn't make a lot of sense to me. Anyway, we'll see what happens.
Anyone else hear anything about replacing the hard drive?

Random Shutdown Problem

Hello I started seeing the random shutdown problem around 6 weeks ago. The problem occurs every once in a while usually around the first 5 minutes of the unit booting up. When the system powers down I will try to bring it back up but it just powers down within about 15-30 seconds again. So I wait a little while about a minute, sometimes removing the battery for 30 seconds and the system will come back fine. The random shutdown has happened probably about a dozen times within the last 6 weeks. It's not causing a real big headache yet. I didn't purchase Applecare as I never do because I rarely keep a laptop for more than a year. My question is has anyone got their unit fixed what was the culprit. I've sent my unit in already once due to receiving a spinning pinwheel 90% of the time. They gutted the unit and sent it back and it has been working fine other than the RSD. I've been waiting things out to see if there is going to be a software fix for the RSD. Any tips recommendations are appreciated.

My question is has anyone got their unit
fixed what was the culprit.
Mine has not had the problem recur after replacing the heat sink a month ago. Currently Apple seems to be replacing both logic board and heat sink with a new design for the combination.

General opinion would say it's a hardware problem; there won't be a software fix.
I'd say you should send in it for repair.

Are the replacement Heatsinks fixing people's Random Shutdown problems?

Is the replacement heatsink (the shorter one) still the method of choice from Apple for fixing Random Shutdown problems?
Is it working for people who've had it done recently?

Does this max out the CPU?
Yes. People who advocate this are testing to see if it's possible to induce a "random" shut down.
Why would anyone want to do that?
Good question. I've seen two reasons put forward: (a) It's better to make it happen now yourself rather let it strike out of the blue at some later date (and if running this test doesn't induce RSDs you can feel confident that your computer is probably immune); (b) If you take your MacBook to an Apple Store it could be useful for demonstrating to an Apple "genius" that your computer has the problem, especially if your shutdowns are infrequent.
(personally, I don't agree with (a))

Did you delete all receipts with iDVD in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/ folder before installing the new copy? If not then do so and delete the new application also.

Do you have the right boxes checked to sync the music to your iPod?
iTunes: Syncing media content to iOS devices and iPod
Do they play in iTunes on the computer?
Have you successfully synced music form this iTunes library/computer before?

I have the new iPad. Even with airplane mode on, my battery life is extremely limited. Is there a problem with the battery? I used to have the ipad2 and had no such problem.

What is your brightness setting & how many apps are open?
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Pro Random Shutdown problem?

So we bought a 15" Pro and it has this odd problem of just randomly shutting down. The battery has power in it and most of the time it is plugged into the wall anyway. Sometimes music is playing or I am even actily using teh laptop and then it just shutts down and I have to reboot. I know I will have to take it in for repairs and/or replacement, but I was wondering if anyone else has heard of or experienced this problem and have any idea what would cause such an issue?

The problem you are describing could be a bad battery. You should check to see if your battery is part of the recall (https://support.apple.com/macbookpro15/batteryexchange/). If it is...there's your problem.
If it's not, it still could be the battery, but you should try resetting the PMU first (http://docs.info.apple.com/article.html?artnum=303319). If that doesn't work, call AppleCare and ask for a replacement battery...
Lots of folks on these boards have described similar experiences....try using the "Search Discussions" feature next time...

Any X301 users having touch pad problems?

Everyone of my X301 units have had a problem where double tapping on the touch pad does not work for a few seconds at a time. Also there can be a few seconds delay waiting on what I typed to appear on the screen. I know the X301 has a lower powered processor but sometimes when I am doing simple word processing these quirks will appear.
Is there a setting to make the touch pad more sensitive?
Is there a setting to move the input of the touch pad up on the list for the processor to handle?
Other than this, the X301 is perfect for me and my employees.

Random Shutdown Problem (External HD problem?)

I've had a problem that's been getting worse recently. My MacBook Pro will freeze up, and a multi-language "you need to shut-down" message will cover the screen at seemingly random times. I've started to notice that this only happens when I'm using iTunes. I have a good amount of music, and it's all on my external hard-drive. I think this may play a part in the error, but I can't tell anything besides that. It's happened after my external HD was asleep and I clicked on a song to play it, and its also happened when my external was awake and playing my music. Also, it happened when I just closed iTunes. To resolve it I have to do a hard reboot.
Any possible solutions? I'm a student, and I don't want it to happen when I'm in the middle of a paper or other projects.

Turns out it is what they call a kernel panic.
http://en.wikipedia.org/wiki/Kernel_panic
http://docs.info.apple.com/article.html?artnum=106227
Unfortunately they don't have much to say as for fixing it...
Looks like I'll have to make a trip to the Apple store.

Random shutdown problem after replacement of new MB

i got the replacement of my MB one month ago due to the random shut down problem. the symptom before the replacement was not only random shut down but also that the MB could not be turned on once a while.
now it's been one month after i got the replacement from apple store, there is no randon shutdown at all, but when i got up this morning, i couldn't turn it on. i tried several times, but it just turned out to be dead. any suggestion about what i'm supposed to do? shall i ask for a refund or a replacement? i'm just afraid of that i would get a defect model again.

thanks for both replies.
i usually close the MB when the shutdown is completed, i know the shutdown won't be completed if i close it right after i shut it down.
and also, i got a whole new mb as a replacement from apple store rather than having it repared and just the logical board replaced. and it's really weird, since it was said the new logical board doesn't have whatsoever problem. i also read some news on tuaw or infiniteloop (i forgot which one it is), the RSS is not really caused by the faulty logical board, it was the heat sink melt by the high temperature coming from the intel processor which shortcut the circuits around it. now i'm totally desperated. it looks like unless apple drops the stupid intel chip, otherwise the RSS will never go ever.

Have any of you had trouble with calls since updating to iOS 4.3.3?

Hi there everyone,
I recently updated my iPhone 4 (from ATT) to iOS 4.3.3 and suddenly I am having trouble making and receiving calls--I am not receiving a great majority of my calls and apparently it goes straight to voicemail. When I try to make a phone call, there is terrible reception and the call eventually drops --but the screen continues as if I am still talking to the person. I know it really isnt a problem with the network becuase a) I have full bars whereever I go, and b) Ive been using this phone for the past 9 months in the same area with no problem!!
Are any of you having this problem, and if so what is your remedy (if you have found one). Should I just take it to the apple store and see what they have to say?
Thanks!

Did you get this resolved? I am having the same problem.

Have any of you had any issues with resizing in Adobe PS CC 2014?

If I resize a photo in prior versions, I have not issues. If I go canvas size in Adobe PS CC 2014, the image becomes larger- but cropped and a color is added as a border. This doesn't happen in the prior versions.

I guess that I should have been more specific, Noel. I compared and contrasted Adobe PS CC 2014 with the CC version and CS6 version. I noticed a big difference. After a couple of hours toying with adobe PS CS6, CC, and CC 2014, here is the difference that I have discovered: in the older versions, if you wanted to make a canvas size like 24 x26 inches, you had to use "Canvas size" under the "Image" tab. In CC 2014, if you do that, it will keep the image looking small, but add a huge border around it. If you go into "Image Size" you can type in your dimensions, and it resizes the image without adding the border. Noel, if you are familiar with resizing images, please talk me through my mistakes. I need to learn, and I have no one in my area to teach me. Your help would be appreciated.
