Mbook needs power button pressed multiple times to start up when on battery

Hey all,
Not sure if anyone's had this particular problem, but here goes:
When on battery power, my Macbook does not power up properly--I have to press the power button 5,7, probably close to 10x sometimes before it goes on. Each time I press the button I can hear it begin to start up but then it shuts down.
Anyone had a similar problem? Or care to speculate on a possible reason/way to fix it? Figured I'd ask before I take a trip to the Apple store.
Thanks!!

Check to see how many battery cycles you have on the battery in System Profiler. Apple-About this Mac-More Info...-Power. Let us know the number of cycles, condition, and maximum mAh.
It couldn't hurt to try a SMC reset by turning off the machine, unplugging the magsafe, taking out the battery, and holding down the power button for 5 seconds.
Next, reset the PRAM by putting everything back in, pressing the power button to turn it on, and holding down command-option-p-r until it chimes twice.
Last, calibrate the battery (if you can get it working). Charge fully and let it sit charged for two hours. Then unplug the power and let it run down fully until it goes to sleep on its own and let it sit discharged for five hours. Last, charge it fully. Do this every 2-3 months to keep the battery working well otherwise keep it charging when possible. The goal is 2-3 cycles per week.

Help - HP Pavilion a6030.uk desktop. Have to press the power button multiple times to start up?

Hi,
I have a HP desktop computer. The model is HP Pavilion a6030.uk, Opertating system: windows vista.
My computer has had no problem at all until yesterday for some reason i had to push the power button multiple times to start it until it finally turned on and did the normal start up. Such as i would press the power button as normal to start it, but all of a sudden, it would turn off after about 2 seconds, and so I would press the power button several times and each time it would not start up and turn off, so the power button would be pressed again until it would finally turn on and start up and run as normal and seems to work fine. And it was the same today, i pressed the power button mutiple times (e.g. 6 times) until it finally started as normal.
As im not very knowledgeable or very computer/technology savvy wise in this area, please will someone help me and give me some advice/help to fix/solve this.
Thankyou for taking time to read this and any help would be much appreciated to resolving this problem.
Thanks.

Vonbon90, welcome to the forum.
When I see these symptoms on an older computer, I believe that it may be a failed/ing power supply unit (PSU). Here is a guide that will help your troubleshoot it.
Also, you could test the memory. This can be done by removing all of the memory modules and replacing them one at a time and booting.

My ipod has a blank white screen. I have tried pressing home and power button at same time and a restore and its still the same. Can anyone help please

Can anyone help me please? My ipod has a white screen that i cant get rid off. I have tried pressing home and power button at same time. I have tried a restore from itunes and its still the same. I cant even turn it off. Please someone help me.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

CFMCPopupMenu is shown multiple times if the menu key (VK_APPS) is pressed multiple times

Hello,
I have a problem with the CFMCPopupMenu in a Visual Studio Professional 2013 Update 4 created MFC DLL (Regular DLL using shared MFC DLL) and in a dialog based MFC application (others I didn't test - maybe in an SDI application too).
If the menu key (VK_APPS) is pressed multiple times, the context menu is created and shown multiple times.
When pressing the Alt (VK_MENU) key or clicking with the mouse buttons the menu is not shown multiple times.
It seems to be bug in CDialogImpl::PreTranslateMessage case WM_CONTEXTMENU where it is tested if a popup menu is already shown
and if there is an active popup menu this popup menu is closed, but only if the pMsg->wParam == VK_MENU.
The problem occurs in a dialog based MFC application and in dialog's in regular DLL's.
In case of MFC MDI applications the problem does not occur,
because in the CFrameImpl::ProcessKeyboard the key is passed to the popup menu for processing pActivePopupMenu->SendMessage(WM_KEYDOWN, nKey); and eaten up.
You can reproduce the problem in the following way:
1. Create a dialog based MFC application with the Visual Studio 2013 wizard.
2. Add a menu IDR_MENU1 to the resource.
3. Add a ON_WM_CONTEXTMENU / OnContextMenu message handler to the dialog.
4. Insert the following code into the OnContextMenu handler of the dialog:
_ASSERT(!CMFCPopupMenu::GetSafeActivePopupMenu());
CMenu m;
m.LoadMenu(IDR_MENU1);
CMFCPopupMenu* pPopupMenu = new CMFCPopupMenu;
pPopupMenu->SetAutoDestroy(FALSE);
VERIFY(pPopupMenu->Create(this, 100, 100, m.GetSafeHmenu(), TRUE, TRUE));
5. Compile and start the application and press the Menu Key (VK_APPS) multiple times.
-> You run into the ASSERT.
If you press the Alt-Key or left click with the mouse multiple times all is fine.
You can also add a tracepoint in the constructor and destructor to see that the CMFCPopup menu is created multiple times if the Menu-Key is pressed.
Kind regards,
Andreas.

Hi Andreas,
Thanks for posting in MSDN forum.
Yes, I can reproduce this issue on my side. After look into the afxdialogimpl.cpp and afxframeimpl.cpp file, It really is a issue in the dialog message translate. I have no workaround to avoid this. But maybe we can try to use
CMenu class and handle WM_RBUTTONDOWN message instead of WM_CONTEXTMENU.
void CMFCPopupMenuTestDlg::OnRButtonDown(UINT nFlags, CPoint point)
// TODO: Add your message handler code here and/or call default
CMenu menu;
VERIFY(menu.LoadMenu(IDR_MENU1)); //IDR_MENU_POPUP是新建菜单ID
CMenu* popup=menu.GetSubMenu(0);
ClientToScreen(&point);
popup->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON, point.x, point.y, this );
CDialogEx::OnRButtonDown(nFlags, point);
By using this, we can avoid the VK_APP message caused multi pop up menu.
Also have you tried submit this issue to Microsoft connect?

I have reached out to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know why it went black

I have reached out to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know
1. Why it went black and is there a permanent fix for this
2.Will the IOS gets automatically updated as I feel the IOS was 5 when I got the phone in 2012 december
3.Do you suggest 7.1 for Iphone 4

1. There is no way of knowing. These things happen.
2. The iOS only gets updated when you want it to be.
3. You should always update to the latest iOS your phone will support. Apple do not write the updates to make your experience worse.

If you are still under warranty and/or have AppleCare, call them. Let them deal w/it. Out of warranty, your keyboard may need cleaning. Use a vacuum hose or a can of compressed air to get the dirt out from under the keys. For instructions to remove the keys if it comes to that check out the following websites:

HT1414 why does my iPhone 5s shut down unpredictably and needs to be reset every time to start back up?

why does my iPhone 5s shut down unpredictably and needs to be reset every time to start back up?

Hi Cyprus11,
Thanks for visiting Apple Support Communities.
If your iPhone is shutting down unexpectedly, I recommend going through these troubleshooting steps:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Best,
Jeremy

QUESTION: flashing power button at startup/won't start

I just bought this Imac intel core duo 2. it worked fine for the first couple of days. Now, when I try to turn it on, the power button (in the front pannel) starts flashing and the machine won't start up :o(
Anybody has any suggestions how to fix this problem?
Imac intel core duo 2 Mac OS X (10.4.7)

Thanks for your quick response Pete!
I definetely feel like I should just bring this back to get a new one since I just got it. Although it went on, once I shut it down it would take me quite a few tries to start up again. Kinda frustrated cuz I got tons of school work to do.
Have a good night! (midnight in nyc)

P35 Platinum: I have to press the power button multiple times to start

Hello fellow MSI customers,
as written in the subject, I have a problem with starting my PC. When I press the power button, the computer powers on, but there is no output to the screen. In fact, my LCD stays in standby mode. I can hear the fans running, so something is going on. According to the LEDs on the mainboard, it is a memory problem.
Now I turn the computer off, using the power button (have to hold it for a few seconds). When off, I start again and everything runs as it should.
After starting, I ran memtest86 multiple times without any errors. I ran a few games, compiled some programs, installed Vista 64bit, Linux, all without any crashes or hangups. It is just the starting that makes problems. After booting it is very stable.
Seeing that it could be a memory problem, I brought another pair of memory, just to be sure. I couldn't reproduce the problem on that day! Any type of memory I put in (the one before, or the newly brought home) the computer always started on the press of the button. So I thought, OK, maybe they were not seated correctly. But, alas, two days later it is again only starting by pressing the power button three times.
What I tried:
1. Boot using only 1 piece of memory stick
2. Boot using only 1 piece of memory, but different one
3. Use another pair of memory <- worked, but on that day it also worked using my original memory
4. Disconnected everything except graphics card, to make sure it is not a power supply issue (minimized power usage)
5. Tried all of the above with a different processor
6. Used another power supply
Any other ideas?
Here are my specs:
MSI P35 platinum
Core2 Q6600
Nvidia 7900GT
4GB V-Data DDR2 800MHz <--- I think this is the problem, any experiences?
Enermax Liberty 400W
a few other things (HDDs, XFi, DVD-RW)
By the way, how can I boot from an external DVD-RW? It doesn't show in the menu when I press F11 (boot menu).
Thank you for any help, muro
And just to let a bit of steam off:
1. I had major problems with the RAID controller (not MSI fault, rather intel) - I put two disks into a RAID 0, then RAID 1 and they always failed after a few boots - member missing on both disks. I was getting angry, so I put them as normal (non RAID) disks and everything is fine since, although no RAID.
2. Installing anything except windows with an IDE DVD-RW is very hard. It took me ages until I got Ubuntu booting (there are guides on the net, google is your friend), and much longer to get grub (boot loader) working. Long story short - if you have multiple disks, use the Linux disk as the bootable, do NOT put grub on the disk where Vista is installed.
3. I have no idea, how to update the BIOS, if I had to. I'm using 1.1 that came on the board. I use 64bit Vista and Linux, none of which is supported to upgrade the BIOS. Any hints how to do it (if I needed to)?

Hello,
now today is the day I've finally received my replacement board. The good news first - it DOES work! Yepeeee!
Now some more information:
The jmicron controller seems to be missing - a screen with something about "Marvel" is shown before the intel raid screen. However, it is only visible for a fraction of second, so I cannot read it. I think it detects my IDE DVD-RW so I'm quite certain it's the replacement for jmicron. I won't miss it - it took me ages to install Linux with the jmicron controller.
The problem where I had to restart the computer sometimes because it didn't even post (RAM error) is gone. It boots just fine now.
I had an extremely long first post - about a minute, but after that it boots very fast now.
anyway, regarding some questions around here - the manual states MSI recommends using an 350W power supply. My 400W is more than enough. Please note - it is an Enermax, not one bundled with a cheap case. My cheap RAM sticks also work very well now. I did try them on different boards before, so now I know I just had a faulty board.
In the end, I can only say this: This is my 3rd board already and it's the first one that works well. As the hardware changed, I presume there were major issues with this board that lead them to make a new revision. What is strange, though, is that the revision is still 1.1, as were my previous two. I pity everybody who had the same problems as I did, but I can now say that I'm very happy about the board now.
Cheers, muro

LV PDA: Detecting Power button press

Hi,
I am developing an application that i want to run on a PDA fulltime, so it'll be started and the power button will perodically be used to stand-by the ipaq. I need to perform an operation when the PDA is powered on in order to reinitialise my DAQ card in the CF slot.
I've found the "First call" VI, but this doesnt give a signal if the ipaq is power cycled. So my question is, how do i detect from LV PDA when either: the pda is powered on, or when the power button is pressed?
Thanks
Matt

I've found a solution that doesnt require checking for power on now. Not sure if this will help you or not..
Basically when the program first runs, i do the init. code. Then each time the program loops i check for an error from the dac card. If there is no error- run the acquisition code. However if there is an error (The pda has been power cycled and the program is trying to reference a card that isnt there) run the init code again and use a shift register to pass the new refnum onwards.
