Hi @ibalpha ,
Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion dv4 Notebook and issue with the Boot time. I would restore the BIOS with this document selecting the reloading the BIOS default settings. This should restore the quick boot option in BIOS.
Hope this helps.
Thanks.

Have not been able to use keynote if it's linked to icloud. It just starts and turns off quickly. No problem if I toggle off using icloud. Any ideas.

Have you updated to the latest level of Keynote on your iPad? Keynote 2.0.1 (1075) - Check Settings > Keynote
If so, there isn't much that you can do other than report this bug to Apple http://www.apple.com/feedback/ipad.html
You could try restarting or resetting your iPad.
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPad shuts down, then press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).

Try starting in Safe mode by holding down the Shift key while booting. Safe mode takes a while to load the OS. After that, restart the computer normally.
If that does not work, start up in Recovery by holding down the Command and R keys. In the window that opens, choose Disk Utility at the bottom and verify and repair your disk. Repair permissions while you are there.

I have been trying to download the movie Prometheus onto my Ipad. It sticks at 793mb and hasn't moved for hours. I have 48gb of space on my i-pad and have hard resetted and turned off and switched back on, always reconnecting with wi-fi immediately. It doesn't resume?
I haven't even received an email stating I have been charged for it???
Any ideas??

Well I have an update. I decided to stay as I was so far down the road. They gave me an engineer appointment of 14 of August which was totally disgusting.
I rang up to complain and was promised a call back as they tried to expediate my request. Never happened.
Whilst on these calls I also questioned the validity of sending another engineer unless they first checked that my local cabinet hard an available fibre port. I was promised and promised that they would put the notes on the call and it would not be a wasted engineer visit.
Engineer came today. Wasted visit - no ports on the cabinet.
He was not even sure why he was sent there knowing there were no ports. Talk about the blind leading the blind.
The incompetency of this corporation is absolutely astounding even when their customers are telling them they are going to fail they lie to your face just to appease you on the phone and move you on.
So I ordered my switch from sky to BT on June 6th.. and so far all I have is a phone line.
On top of this I noticed that they have charged me a late payment fee by DD and full line rental for first month. BT were so slow at installing it all that my up front line rental apparently did not cover their initialy switch over. Despite telling me I would not be charged I have been charged.
Now as a web designer I am now tempted to create basic website and use my SEO skills to push it to top of google rankings sharing with everyone of my experience of BT.

When you plug it in to iTunes does it show up under devices? Try restoring it. That's the best thing you can do if you're out of warrenty

ILOM feature "Graceful Shutdown and Power Off"

Hi,
We are using Sunblade 6250/6270s, with a stripped down SLES linux installed. We would want to be able use the ILOM feature "Graceful Shutdown and Power Off", but have failed doing this so far. What is required from the configuration and/or operating system to support this power off alternative? I have searched but not found any information on this topic.
Thanks,
Harri

The ILOM "Graceful Shutdown and Power Off" equal you press power button.
The SLES GUI (init 5) it will popup a window to let you confirm your action when you press the power button.
In the command line interface (init 3) when you press the power button your system Graceful Shutdown and Power Offed.

Disable "Power on" and "Power off" buttons in VM Manager 2.2.2

Hi Everyone,
I'd like to modify the role "user" and disable the "Power on" and "Power off" buttons so that a username that logs on to the VM Manager that belongs to the user role cannot power on/off a VM. Is this possible?
Many Thanks

The only way of tracking this up would to be to setup multiple individual users. At least you could see which user then powers off / on a VM from the list of jobs on the gui..

Why does my Macbook Pro with newest OS completely FREEZE when it comes out of sleep mode? Need to hard start with power button. Hating Apple right now.

Lumia 625 wont start after power off!

I bought a lumia 625 5 months ago and it worked fine. but recently when i switch off power it wont turn back on. So i had do keep it in air plane mode at night. After like one hour it switches on back. I tried resetting and restarting. Phone only vibrates after i release power key ( in all resetting methods), but does not show anything in the display. How can i fix this. help would be appreciated

I'm going to suggest a hard reset of the phone. Do a backup first, then either go to Settings/About and select Reset my Phone, or for the 625:
Warning! All data will be lost!
1.Power off your phone
2.Press power button and after phone vibrates once press volume down until you will see exclamation sign on the screen
3.Press in this order:volume up
volume down
power
volume down
4.Wait until format ends and the phone restarts
I'm thinking that something with the sleep mode has gotten corrupted in memory. If this doesn't clear the problem, then you likely have a hardware/firmware fault and the phone should be taken in for repair or replacement.

Difference between Reboot and Power OFF/ON

Hi Community,
in a forum a User is reporting serious problems after an update to the actual major release 10.6.5. He said if he boot the system in safe mode everything works as expected, after a reboot the same but after a power off and on again, the system is freezing after the login.
Now I'm searching for the difference between this two start methods, maybe we can isolate the problem a bit easier.
Thx & Bye Tom

If the operating system is running when the power button is used to stop the computer, this can do great harm to the disk by not allowing all of the data to be written to disk as it should be.
Yes I agree but this wasn't what I'm asking for. The question is why the system works fine as long as the User proceed a normal reboot and why it is broke after a shutdown. I don't believe that the User enforce a dirty shutdown after he boot the system in safe mode. But sure, if he boot the system after a shutdown, and the system is freezing, than he have to proceed a dirty shutdown. What else could he do?
Thx & Bye Tom

Major Freezing and Power off problems.

So this is going to be kind of a long post, but if there is anyone out there who knows what the **** I can do to solve this issue I would really appreciate it. I bought an 8gb iPhone when they were first released last summer. Just 2 days ago the phone started to power itself off if it had been in sleep mode for more than a few minutes. I tried everything in the book (reset, reset settings, restore, etc.) Nothing helped. I went to an apple store and since the genius there was able to reproduce the issue they just gave me a brand new phone right there. Awesome right?! Wrong! After syncing the new phone with iTunes I am now having even worse issues. The brand new phone powers off in the middle of calls and other apps. And sometimes the phone will freeze completely. I tried everything in the book again. Finally I did a restore, and this time tried erasing all media content (music, photos, videos.) This seemed to do the trick as I didn't have a problem all night and pretty much all day. But just about 15 minutes ago the same problems started again! I'm losing my mind over this! Please help!

It was taken out of a white box at the store. On the side of the box there was a label that said "Replacement 8GB iPhone."
You probably got a bad refurbished unit. It happens. If they rebuilt a unit with an intermittent problem, and they don't catch it during testing, the next guys going to have a problem. I repaired a lot of RCA XL-100 solid state modular TV sets in the 70s. Every module we got from RCA was rebuilt. I would say we had problems with about 10% of them. They would work out of the box, but usually would act up after they got warm.

Fake lockscreen and power off screens appearing and cant slide slider on fake lockscreen

hi i have been having my screen frozen with a fake lockscreen with slider that wont slide i know it fake cause its not my lockscreen pic its my homescreen pic and when i try to power off then it show a fake power off slider i end up having to reboot

I Have been having the same problem sporadically and it is most certainly a fake lock screen, exactly as you describe. I have never jail broke my phone nor iPad.
it is really annoying and only happens sometimes. I have even seen the real lock screen and go to swipe it and it immedistely changes to the fake one and wont swipe. I have found i can swipe up in the camera icon and get the camera to start then cancel that and will be at main screen, but that means i have to leave the camera accessible on the lock screen.
it seems to come and go, i also noticed if i wipe ipad and reinstall OS, it wil usually not happen for a month or so then it is back.

Kernel Panic and power off

Hi all,
I have now for a couple of days Kernel Panics and auto power off of my iMac G5!
I have experienced KP in several occasions. Notably (can be reproduced) in iPhoto when I try to order prints online. The dialogue box pops up and then after 10 sec I have a KP!
Also some KP when viewing clips with Quicktime (wmv with Flip4Mac as well as plain mov files!).
Note that my software is up-to-date. I re-applied the combo Mac OSX 10.4.8 but that did not help.
I did reset the MPU and now I even have the iMac powering off (actually crashing badly).
For info, I have experienced KP at sleep mode since day 1! I rally fear an hardware issue.
Question: how can I trouble-shoot Kernel Panics?
PS: I have rebuilt the authorizations, no luck...
Thanks

Hi, Emilio.
