Why does Satellite Pro A300 not start when the power button is pressed?

Suddenly my new Satellite Pro A300 will not start correctly when the power button is pressed. The situation is this: When I press the power button the Toshiba opening picture (Leading Innovation) appears and disappers quickly. Then there is a black screen for about 30 seconds. Then there is a rectangular frame with the text Microsoft Corporation underneath. And nothing happens however long I wait.
In order to get on with the starting proces I then shut down the computer by pressing down the power button until the computer stops. ("The hard way to shut down")
Now I press the power button shortly to turn on the computer. Then the computer starts normally with the Toshiba opening picture and after a few seconds I am asked to open the computer in safe mode or in normal mode. I now choose to open in normal mode and the computer opens normally and is ready to work.
What shall I do to get a normal start procedure?

When notebook starts normally (after choosing normal mode) shut down your notebook properly using START > Shut down option. Next start should be normal.
When the OS is switched down on irregular way you will be always asked how to start it again (safe or normal mode).
The same happen on my Satellite A300.

My Macbook Pro 17" 2.44ghz all of a sudden one day decided to not boot up. When the power button is pressed the sleep light in the front on the latch release turns on and there is a small running sound but it never boots up and the screen never lights up. Anyone else have this problem? Any ideas?
I'd love to repair it but not if it'll cost 500 bucks or more to replace the logicboard.
I appreciate any help

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

Satellite Pro U400 sometimes freezes when the power cord is plugged in

Hello! I know this problem has been discussed here and there but I would like to open a new thread on that. Here is the scenario.
I have recently bought a new Toshiba Satellite Pro U400-247 (PSU45E) with two batteries: (a) the original one, (b) additionally purchased Toshiba genuine PA3636U-1BRL, 7200 mAh. The notebook has the latest BIOS (4.80) and the latest drivers downloaded from Toshiba and installed (ConfigFree is not installed). I am using XP Pro SP3 (clean install done by myself). Everything is working very well, except for one thing:
Sometimes (but not always), when the notebook is working on battery and I plug in the power cord, everything freezes and I have to restart. Some observations:
(a) it tends to happen more frequently when the low battery alarm has already sounded;
(b) it seems to happen more frequently with the 7200 mAh battery and less frequently with the original battery;
(c) it seems to happen more often when a USB device (e.g. mouse) has been connected with the notebook, but that is not a rule;
(d) it seems to happen less frequently when I move the USB mouse at the time I am plugging in the power cord;
(e) I have experimented a lot with Toshiba PowerSaver's settings (e.g. changed the CPU levels for my profiles) but nothing I have modified seems to change the situation;
(f) I have tried various suggestions I found on different forums, but no avail (e.g. BIOS settings);
(g) otherwise, I can say that I really have not seen a smoother computer, everything else is really working just fine, no other problems whatsoever :)
All this makes me think that this must be some kind of bug in the motherboard drivers, the PowerSaver driver or other drivers interacting with the battery, the CPU or possibly USB. Is there an explanation for this problem and can it be rectified somehow (e.g. by providing a driver update)?

Hello, thanks for the reply!
My bad, of course I meant the chipset driver. That, however, does not change the essence of the question. Also, I know that a notebook should function properly even the AC adaptor is connected or not connected. That is why I posted my question.
As for the OS reinstall, sorry, I would not do that just on some wild guess from somebody. I recently finished the clean OS install. I have installed XP on dozens of notebooks in my life and I know what I am doing. I have been into computers and networking for 15 years and I know when I see a problem not related to how I install my OSes.
My personal opinion: this problem has not to do with the OS install since the same problem also existed when I test-installed the XP OS image from Toshiba's own downgrade CD (that was before I did a clean install from my own slipstreamed CD). And, if you really use a properly and carefully configured OS with all the necessary software, an OS reinstall is not something you just do every day.
As for the rest (testing the memory / adapter / motherboard etc.): as I have mentioned, similar (although not identical) topics have been raised in various other instances (e.g. at http://laptopforums.toshiba.com/t5/B...EABCA64EE6C5D9) . That means that this problem is most probably not specific to my computer or even to U400 but it may happen with other Toshiba notebooks too. Therefore a (rather standard) suggestion to spend days on reinstalling (and in my case, carefully reconfiguring) the OS, checking the memory, adapter, mobo etc. does not sound as the most plausible one in this case. FYI, I always do full tests on hardware right after I have installed an OS. In this computer, all tests (Toshiba's own; 3rd party memory diagnostics, HDD diagnostics) were passed OK. Indeed, I did not have the AC adapter tested but as it otherwise works fine, the possible problem (if there is one) would be a minor one to notice, and would require testing at a Toshiba service centre (there is no direct Toshiba agency in my country). I think testing the AC adapter is the last resort as much more probably, the problem lies somewhere else.
Even if this problem is hardware-related, I do not expect Toshiba to replace all such hardware out there. However, on many occasions, hardware-related problems can be cured or alleviated on the software side (e.g. by a driver or BIOS update). Since it seems that other people are having similar problems with Toshiba hardware/software, I thought that maybe someone has found an actual solution or maybe there are Toshiba employees reading these forums who could look into it.

HT3964 My Macbook Pro did not respond to the power button, and I ended up resetting the smc. After that, it would start, but the keyboard would not respond, pnly the trackpad. On the screen there is a symbol with ahorizontal white bar and a row of empt

After resetting the SMC the keyboard is inoperative. On the start screen appears a traslucent square with a horizontal bar in white, and a row of empty dots below (the same format as for example the brightness symbol). I cannot turn the Mac off with the power button, only with the trackpad, clicking on the turn off symbol on the screen.
When I try to login with my username, no characters appear as I type.
I can login as a guest, but from there I can do nothing, because the keyboard is still inop and if I wanted to, for example, have the software updated, I need to type an admin login, which is impossible.
Thanks for your help

What happens if you close the lid? Sleep?
In your place I would use sleep state to reset PRAM, as it can resolve your graphical mess.
Your keyboard likely was not powered after SMC/PRAM failure, so you will need to open MBP cover without opening the lid and disconnect battery power cable with insulated tools from logic board, wait for 5-10 minutes, then try to reset PRAM while keeping cover

Why does my macbook only turn on when the power adapter is plugged in?

The battery life says its at 73% and climbing but whenever I unplug my power adapter the mac automatically shuts down and if I try to turn on the macbook without my power adapter plugged in, it wont turn on. How do I make it go back to where I can turn the mac on without it being plugged in? Thank you for your help!

I would try two things the first being resetting the System Management Controller:
1) If the computer is on, turn it off.
2) Disconnect the AC Adapter and remove the computer's battery.
3) Press and hold down the power button for 5 seconds and then release the button.
4) Reconnect the battery and AC Adapter.
5) Press the Power button to restart the computer.
If that doesn't work I would recalibrate the battery.
To calibrate the battery:
1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5) Turn off the computer or allow it to sleep for five hours or longer.
6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

How do I set up my MBP so that a message does not pop up when the power button is pressed?

When I press my power button on my retina a message that says "Are you sure you want to ..?"
How do I set it up so that that message does not pop up?
My friends keep turning off my computer..

Tell your friends to leave your computer alone. That's not the proper way to turn off your MBP. And no, that message cannot be turned off. It is a safety feature.

Macbook Pro not starting without Holding Power Button

Hello,
my Macbook Pro (bought March 2008) seems to be dead.
When the power button is pressed (and ONLY IF HELD.. cause if I just push it once it powers up and turns off instantly) it starts and does 2 seconds of normal boot (DVD drive check, HD starts to spin along with the fans) then the power just cuts out and you hear the HD off sound. The LED on the front at this moment keeps flashing and then all goes off.
I tried doing a SMC reset and even a PRAM reset already, but no luck. I've read to try an Hardware Test with the Install DvD so I've inserted it but the MacbookPro powers off before even starting it (The Screen never starts )
What should I do?
Thanks for your help :-S

I already tried with the Battery in and without but no luck. I'm sure it's not that kind of problem unfortunally

My hp Pavilion p6230y died. It will not boot. The power button LED does not lite.

The power supply LED is lit, and all the voltages are correct (metered). The fans turn on when the power button is pressed, and I can feel the HDD turning and it gets warm. I stripped the system down to bare essential, nothing but wireless keyboard & mouse, HDMI connector to monitor. I cleaned out all the dust from inside the computer.I reseated the CPU chip. No beeps at all coming from motherboard. The CPU heatsink is stone cold. I suspect either CPU chip &/or motherboard. Anybody have any ideas?
This question was solved.
View Solution.

Usually when the fans twitch it means that the CPU is OK. That is not a theory, it is practical experience. My next step is what I suggested to you. Clear the CMOS settings. That is usually a last ditch effort. I always have a spare PSU around to verify that it is not the culprit.
Follow the troubleshooting on this HP web document to check your PSU. Just testing it with a meter does not help much because it can fail under load. The multimeter does not put a load on the power supply unit. Even those cheapie PSU testers are pretty worthless, except for a cursory test.

WHY DOES IT SAY BATTERY NOT CHARGING WHEN I TRY TO CHARGE MY IPAD??

WHY DOES IT SAY BATTERY NOT CHARGING WHEN I TRY TO CHARGE MY IPAD ???

How are you trying to charge it, via a computer or the wall plug ? If a computer, then a lot of computers (especially older ones) generally do not provide enough power to their USB ports to charge the iPad at a sufficient rate - it may still be charging slowly, and should be a bit quicker if the iPad's screen is off (if you leave it for a while and then disconnect it from your computer you may find that it's battery percentage has gone up). The wall charger is usually the most efficient way to charge the iPad.
If the wall charger then have you tried a reset to see if it charges after the iPad has restarted ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
If that doesn't work then have you tried a different charger and/or cable ? Do you know anybody else with an iPad so that you can try their charger and cable and they can try yours ?
And for info typing in capitals is considered SHOUTING.

Read the KB article. Make sure you are using the 10W adapter that came with the iPad or a High-Power USB 2.0 port.

If you are running Tiger, you don't have time machine.
You need to get something like SuperDuper! or Carbon Copy Cloner (sorry, I don't have a handy link for CCC but you can Google it to get their site) to make a clone of your drive on the external and then do incremental backups. The free versions do a lot and you can upgrade to the full-service versions for small change if you need more. The one time I used SuperDuper! for cloning a volume it worked just fine.
(My backup application is the last PPC capable version of Retrospect, which does a credible job, or has over the past ten-twelve years.)

Mac Book Pro will not start on Battery Power

Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

What is the exact model of your MBP? The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
If the SMC reset does not solve the situation, post this from your MBP:
Make certain that the power adapter is connected.
Ciao.

Why does my photo's not email on the classic or journal view? It appears blank.

Why does my photo's not email on the classic or journal view? It appears blank and no photos are emailed. I don't want to always use the themes

Make a temporary, duplicate copy of the library and try the two fixes below in order as needed:
Fix #1
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your Home/Library/Caches/com.apple.iPhoto folder.
3 - reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select the options identified in the screenshot and the option to rebuild the small thumbnails.
Click to view full size
Now those two templates again.
