Laptop overheating and automatically shutting down

I have a Compaq Presario A900 laptop. It always had overheating problem for which I have a cooling pad. However, for the last few days, the overheating phenomenon has increased and the system is shutting down automatically... Please help.......

HI;
The easiest thing to do is to spray canned air into the vents by the fan and heat sink. If a lot of dust comes out, that will probably take care of the issue. If no dust comes out, then you have other issues causing overheating and thermal shutdown. Take care not to overspin the fan blades when you blow the air into it.

Compaq Presario CQ60, overheating and automatically shutting down.

Hi.
I have a Compaq Presario CQ60 that is about a year old. These days I have been experiencing problems with my laptop. The problem is that the top hand corner gets hot, and then my laptop automatically shuts down itself. There is plenty of battery on my laptop, and it also happens, while my charger is plugged into it. This mainly happens when I am at school, where I do not bring my notebook fan cooler. I can basically do nothing, because every 30 minutes it will automatically shut down itself. It even happens when I am in "Battery save" mode. This is starting to irrate me, because I have only had this laptop for about a year, and my warranty just expired so there isn't much I could do. I have read about this being a problem to a lot of people...
I am wondering if it has something to do with my battery, because it is really bad. It only lasts for about 30 minutes from 100% to 10%. I do not know what the problem is, because I have no expertise in laptops.
I hope you can help me.

Dreaded Black Screen and automatic shut-down. Why does this happen ?

Why do I get a Black Screen and automatic shut-down ? My iMac felt warm...and I never hear a fan go on..could overheating be why it shuts down?

Hi Tish,
A few things.
If you bough this iMac used with no original install/hardware test discs, you can call Apple at 1-800-MYAPPLE ask for software sales and tell them you need a set of iMac replacement install/hardware test discs. You'll need to give the Apple rep your iMac's serial number.to get the appropriate discs. There will be around a $16 or $17 U.S. charge for discs.
Since your iMac is still freezing, I now wonder if it is RAM and/or hard drive related.
Your iMac maybe freezing because of serious lack of RAM.
How full is your Mac's hard drive?
You only have 1 GB of RAM installed.
OS X 10.6 Snow Leopard really needs more RAM than this.
Intel versions of OS X use more CPU, GPU, RAM and hard drive resources.
OS X, running alone (without any other applications running) can use up between 2 and 4 GBs of RAM memory.
Youf iMac model can 4 GBs of RAM, but only about 3.1 to 3.3 GBs of it will be recognized.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Without being able to run the Apple hardware test we have no way of knowing the condition of your iMac's hard drive.
The freezing could, also, be caused from a failing hard drive.
If you do not have any backup of your data, this is the time to create one.
Backup your important data to either DVD discs, flash drive/s or purchase an external hard drive to backup all,of your data to.
You can make an exact clone of the data, on your internal hard drive, using a data cloning like CarbonCopyCloner or SuperDuper. OR purchase the external drive and use OS X Time Machine to automatically backup your entire internal drive.

What does it mean if my computer turns on and automatically shuts down a few seconds later?

I tried to restart my desktop but every time it tries to reboot, it automatically shuts down within 30 seconds. Is there an easy resolution for this or do I need to bring it in?

Loud grating noise and automatic shutting down

I was writing on a blog and had created a new Wordpress page. I had not written any title nor had put any content in the body either. I chose "Pending" instead of "Draft" and went away for ten minutes.
The problem I have had with Wordpress is that it saves the draft every five minutes and with long pages or posts, the frequent automatic saving freezes the Firefox web browser I use and will cause me to Force Quit Firefox. This happens frequently - almost every time I edit a Wordpress post or page. I have to admit the post or page is usually very long and contains many images - about a hundred.
Today, I created a blank new page and went away. When I returned to the computer, I pressed a key to get going, and then a loud metallic rattling noise started plus a shadow descended over the screen.
There was a message along with this shadow that said I need to shut down the computer by pressing the Power button for several seconds, which I proceeded to do.
I then waited a minute before booting the computer.
A message came up that asked if I wanted to submit an error report to Apple as the computer had shut down in a funny way, and I submitted the report.
The only weird thing I did before the computer shut down was creating the page in Wordpress. Perhaps Wordpress.com doesn't like saving empty drafts? Maybe it created endless loops or took up all the space in the cache or something to cause my computer to act up ...
The noise was very loud. The laptop is the late 2010 model with SSD drive 250GB and 2.16 GHz.
Any opinions as to the likely the cause of this strange phenomenon?

I would boot from your USB restore drive (hold down D during boot) and run extended diagnostics to see if any hardware issues are detected. If none, watch it like a hawk and contact Apple support to follow up.

I have a late 2008 iMac with dual intels and the fans won't come on anymore. About every 1 1/2 hours, it automatically shuts down to cool off. Is there any way to manually turn it on? Or, do they have to be replaced?

About every 1 1/2 hours, it automatically shuts down to cool off. Is there any way to manually turn it on? Or, do they have to be replaced?

I tried that with no improvement. I think I might have to have the fans replaced. do you know if this is a particularly difficult procedure? Something wierd that I've noticed is that if I have a video on for more than several minutes, the fans comes on, and also when I am on a Skype video conference for awhile. Otherwise, the fan jst doen't come on as the intels heaten up to the point the the auto shut down kicks in...any advise? This definitely interupts my work! Thanks for your help and input thus far!

When I start iTunes on my home computer (Not a MAC), it automatically shuts down, and gives me the message that the Data Execution Prevention security feature has shut it down...what to do?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

HT4061 my ipad automatically shut down and now i lost al savings and in-app purchases the battery was on 50% what happened and can i get my purchases back

my ipad automatically shut down and now i lost al savings and in-app purchases the battery was on 50% what happened and can i get my purchases back

Hi there,
This seems very frustrating. An iPad can shut down randomally for many reasons, just like a computer can crash. If it begins to happen regularly, then do contact Apple, but there are no signs that your iPad is malfunctioning from just one shut down like this.
But, you should be able to get all your in-app purchases back. In some apps, there is a 'restore purchases' button, which will download all the purchases you made for free.
In some cases, you can tap to make the purchase again, and it will be downloaded at no charge, however this does not happen with consumable items such as coins and credits.
I reccomend contacting iTunes Store Support at the link below, they will take a closer look at your purchases and give you further steps on redeeming them. They may also refund you if they have been lost.
iTunes Store Support
You can also contact the developer of the app, and report the crash and missing purchases. If you tell me the app, I'll give you the relevent contact in the developers.
Other than that, sorry for the problems, and have a great day,
Nathan

Second replacement unit automatically shuts down and never opened again. can i asked for a brand new replacement since it'll be my third replacement?

Last September 13, 2011 I purchased an Iphone 4. I was told that it's warranty is good for 1 year. On may 13 2012, the sleep/wake button of my iphone malfunctioned. I immediately brought it to store where i bought the unit. They sent it to Singapore for service. 10 days after, on May 23, 2012, I received a text message from them telling me that my "replacement unit is available for pick up". Meaning that my old unit was replaced. When the customer representative and I checked the replacement unit issued to me, we saw deep scratches in front and back of the unit. I returned the unit to them because of the deep scratches. They told me that they'll return it to Singapore and will make a new report. Comes June 12, 2012 when i received a message again from them saying that my replacement unit is again available for pick up. the customer service representative and I checked the unit again for scratches. Finally the unit is clean. On June 23, 2012, the replacement unit issued to me automatically shuts down for 8 times. i quickly brought it to the store. Even their security saw the problem of my iphone (because he helped me troubleshoot it first). on the last time we tried opening it, it hanged and didn't continue to open. So for the third time, the unit is again subject for check up to see if it is under warranty. my concern is, apple is very vocal about their warranty which is "replacement".. Is there anything I can do to ask for a good unit from apple since this matter is a big inconvenience for me where in i have to provide myself another phone where i can use my number. and the worry that i might get another bad replacement unit.

Of course you can ask... asking is always an option. Regardless, it is always up to Apple as to whether the device is replaced with service units or new.

Powerbook 17" G4 automatically shuts down in sleep mode

Powerbook 17" G4 automatically shuts down in sleep mode intermittently. When press power button to bring it back up, it takes a very long time to reboot and the date is set to Dec 31, 1969. It comes back up finally, but this is irritating.
Thanks for any help,

Hi Reaskt
Have you tried using Temperture Monitor to monitor your temps? Maybe it is overheating. Also it sounds like your backup battery is dead, that's why the clock reset's it's self. If you still have applecare I would give apple a call a soon I could. To me it looks like you would need a new logic board. I realy hope that you have applecare. Also have you tried an Erase and Install? Have you tried running Disk Utility booted from your install CD?
Post back when you get more info

X200 Series 7454-2JU Automatically shutting down.

Hello All....
Long time reader, first time poster. Anyways i am having an issue with a couple X200 Series laptops.
The users are reporting that the systems are automatically shutting down with no warning or error messages. Both systems are running Windows XP SP3, fully updated, and have the Lenovo Systems updates.
I have read somethings online about setting the Automatic Recovery in Windows which i have tried, but with no avail.
Is there anyone who has experienced the same issue? or is still experiencing the same issue?
Any help is greatly appreciated
Thanks

mikiexu,
we came to same conclusion that it mostly happens when it's in the ultrabase. We ended up rebuilding one of the x200 machines and the user was working fine. A couple of other users whose pc's we rebuilt still had the same issue. We concluded that somewhere there was software causing us to drink a 24 during lunch.(JOKE)
BUT....i think i found what is causing the issue. Look in the Scheduled Tasks in the Control Panel. If you see something there called PMTASK...DISABLE IT.....it is used as power management to set the machine into hibernation, dimming the screen etc. my gut tells that this is causing the problem

Laptop battery drains after shut down

Hi, I have bought hp pavilion 15-no28se six months back,
Its working good, but one issue is contantly irritating me, it is due to its battery drainage after shut down overnight.It almost drains 8-10 percent withing 12 hours. Whereas, I properly shut down it and caliberated as well, but of no use. Although, battery status is OK, and I think battery is fine becasue once I took out battery from laptop for 24 hours, then inserted again and checked it and not a single percent dropped down.
I am so tense that why it is draining when battery works well and properly shut down?Please guide me on this.I am waiting..

Hello again rocket_sc,
I hope you had a great weekend!
To test, calibrate, and re-synchronize your battery you will need to first follow the steps in this document on Testing and Calibrating the Battery (Windows 8). Once this is completed, and the battery continues to drain, then you can move to re-install the ACPI-Compliant Control Method Battery.
I understand that this process can be a little overwhelming, but not to worry! I would gladly expand on the steps provided above!
To answer your first question: you are not uninstalling the software as you would from Programs and Features (like uninstalling software downloaded from a CD). Instead, you are removing small driver components removable from the Device Manager.
To get the Device Manager, please follow the steps below:
Step 1. Go to Device Manager:
a. Press the  and type "Device Manager"
b. Click the Device Manager tab on the top right-hand side.
c. The Device Manager should be open.
Step 2. Select Batteries:
a. Click the right-facing triangle to the left hand side of "batteries"
Step 3. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there
a. If you see any duplicates of the "Microsoft ACPI-Compliant Control Method Battery", please select them both.
Step 4. Click Uninstall
a. You might also see an option that says "disable." Please disregard this option, and click on Uninstall.
Step 5. At the prompt put a check in the box to remove the current driver
Step 6. Restart the computer
Step 7: Remove the battery for one minute and then put it back in
When the computer comes back up it should automatically find and install the driver.
Step 8. Go to Device Manager
a. Press the  and type "Device Manager"
b. Click the Device Manager tab on the top right-hand side.
c. The Device Manager should be open.
Step 9. Select Batteries
a. Click the right-facing triangle to the left hand side of "batteries"
Step 10. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there (there should only be one).
Step 11. Click "Update Driver Software"
Do the same thing with Microsoft ACPI-Compliant Embedded Controller.
a. If you do not see this parcel of software in the Device Manager, please skip this step. If you do, the same steps would include:
* Right-clicking this device driver in the Device Manager
* Click on "uninstall"
* Put a check in the box next to "remove the current driver" and pressing "ok"
* Restarting the computer
* Remove the battery for one minute, then re-insert it
* Return to the Device Manager
* Right-clicking the Microsoft ACPI-Compliant Embedded Controller
* Click "update driver software"
Please re-post with the results of your troubleshooting, and I look forward to your reply!
