Help please laptop wont boot!

ok so the laptop in question is a satellite l455-s5975. when i turn it on it shows the toshiba screen and thats it, if i listen it makes a weird noise,kinda sounds like a car that wont start. i tried pressing f2 to enter setup and it just says please wait and does nothing. any clues? any help would be great thanks!

you need to know how to remove that hard drive from your computer, and slave it using an hdd enclosure so you can access your data from another computer. Did you try loading BIOS to default? it might help..

My HP laptop wont boot for no reason.

My HP laptop wont boot for no reason. I can read my hard drive in my enclosure attached to my desktop but it wont boot in the laptop. Can anyone advise on this issue if you have experience this before? Greeks can jump in too.

My suspicion is that somehow the order of the boot table in the bios is off. What is the computer set to boot from first?

Pavillion zv5000 laptop wont boot from cd after mobo and hdd replace

So I inherited a dead zv5000 laptop with no hdd. I replaced the motherboard and CPU, and it powered up and booted from the cd drive with no hdd installed. I was able to run memtek and the original hp os recovery discs, with no hdd installed.
Then I put in an empty hdd. The bios sees the hdd ok, but I suddenly can't boot from the cd drive. The bios settings are correct, and the discs spin in the cd drive, but it wont boot with the recovery discs, memtek, or an original xp install disc.
When I remove the hdd, it still wont boot from the cd drive.
So I google and I read stuff about hp tattoos on hdds and motheboards and dmi, and no passwords for the average person to do the tattoo.
So what do I need to do ? I don't understand why it was good with the new motherboard, but as soon as I plugged in an hdd it wont do anyting. I cant update bios because I cant boot past the bios, and not sure how that would help anyway.

If you have an open firmware password, delete it. It will not boot off anything but HD with OF password. Or at least thats what it was for me.

HELP PLEASE!! Boot problems with Snow Leopard (Blue Screen Loop)

Hi guys!
My MacBook (the model before the current one) wont boot up. It started stuttering and acting strange and then froze so I did a force restart. It then loaded all the way up until a blue screen when the mouse appears and can be moved. This flickers off after a few moments (the screen dims) and then comes back. The process repeats as if in some infinite loop.
The main problem is that I've lost my snow leopard disc so I'm pretty limited to what I can do until I can borrow / buy another one and I need to get my laptop back up right away for work.
I've tried booting in safe mode, no joy
I then tried to repair the drive in fsck, which repaired something. I did it again and it said all was ok but then booting stuck at the same place.
Finally I read on another forum that removing /Library/Preferences/com.apple.security.plist fixed login loop issues. I attempted this in single user mode but it said the file didnt exist?
Can anyone help me out here? I'm pretty stressed out as all my work stuff is on there for my new job...
Thanks!!

I had this same problem -- machine would boot, but loop at two blue screens before the login window. I sshed into the machine and checked /private/var/log/system.log and /var/log/secure.log which showed a unexpected character in /etc/authorization. Basically, the authorization file was corrupted (most likely by bad RAM.) The solution was to replace this file with one copied from another machine. I didn't match models, but did match OS when copying the file (i don't know if this matters at all), and as soon as the "cp" command was entered, the login window popped up. <-- totes awesome. The machine has been reliable since (all of 15 minutes)

Help please! Wont let me do upgrade?!

My brand-new Macbook I've had for two days won't let me download the software upgrade it says I need. It stops unexpectedly and says it can't download or says it doesn't have a network connection every time but I'm connected to wifi?? Help please!!

you want MacBook Pro forum, and/or Mavericks too.
Your system may have a system build that is not qualified, higher build number, than the public update on the software update servers.
otherwise you can get online etc?

Laptop wont boot with new memory installed please help

Hi I am trying to upgrade my laptop memory to two gigs When putting in the I gig modules in each slot the laptop will not boot. When I put in the original 256 memory module in slot one and the 1 gig in slot two I get it to boot and it only recognizes the 1 gig slot. Even with belarc it shows only slot one with 1042.

When putting in the I gig modules in each slot the laptop will not boot. When I put in the original 256 memory module in slot one and the 1 gig in slot two I get it to boot and it only recognizes the 1 gig slot.
That sort of thing is typical of incompatible modules. Turns out that unless you order your add-on memory from Toshiba or buy memory made by Kingston, you'll likely as not have that difficulty.

Please help! emac wont boot after installing os 9 alongside os x!

Hi,
I am a teacher. My school recently gave me an emac to use in my classroom that has Tiger installed on it. I have a bunch of OS 9 games that I want the kids to be able to use, so I decided to try to install OS 9 alongside os x. I just installed OS 9 on the same partition as os x using an OS 9 emac installation disc. I had to install OS 9 on the same partition as OS X because I am not allowed to repartition the school computer. I tested out classic in OS X, but it didn't play the games well. I then tried to boot naively into os 9 by going into system preferences, then to startup, and then selected OS 9 as what to boot into. When I restarted, the only thing I was left with was a floppy disk with a flashing question mark inside. I tried to boot back into OS X by holding the option key, but my only option for booting is OS 9. I then tried to boot back into OS X by holding down the "x" key, but it still tries to boot into OS 9. Could someone please help?
Thanks!!
-Stacy

Hi, Stacy -
Since the machine boots to the OS 9 Install CD, it is indeed OS 9 bootable, by definition.
Since the installer on the CD was able to 'see' the destination drive, then that drive does have OS 9 drivers on it.
Those two are the primary causes for a machine not being able to use OS 9 as a boot OS.
I assume you accepted the default install of OS 9 and did not customize it. If that is the case, then it should have installed all files needed by your machine in order to use it as a bootable OS.
About all that is left is make sure that the OS 9 System Folder has been blessed - registered as a bootable OS. To do that, boot to the OS 9 Install CD but do not run the installer. Instead, open the icon for the hard drive (if it is not already open), locate and open the System Folder (not the folder named just System - that's OSX). Drag the files named Finder and System (both are loose in the System Folder's window) out to the desktop. Close the Syatem Folder. Then drop those two files back into the closed System Folder.
Once that is done the System Folder should be displaying a miniture glyph of the Mac OS logo superimposed on the icon for that folder.
One other question, re the CD you used for the installation. Was it a Software Install CD specific to that machine (does it show eMac on the label)? Or was it a retail OS 9 Install CD (white label, gold 9)?

6735s.Failed Charger, Now Battery Playing Up? Laptop Wont Boot with Charger Plugged in!

Hi,
I have a HP Compaq 6735s and have owned it for around 2 years.The OS is windows 7 Ultimate, I have the installation CD.
The other week my charger for the laptop broke, and I ordered a new one from Amazon. The charger was advertised as an orginal/genuine HP charger (although I doubt it is).
As soon as I got the charger, I put my laptop on charge, The orange light around the charging socket came on to indicate it was charging. I leave it half hour to an hour and try to turn on the laptop. All i get is the fan on and nothing else, I pulled out the charger for a split second and the laptop boots fine. However, I left the laptop on charge overnight, and it gained only 9% charge!
When the laptop is on, and plugged in, the fan is on. As soon as I unplug the charger, the fan turns off. When the charger is unplugged, the ring around the charging socket will flash orange, and the battery will decrease very fast! Once the laptop has been powered on, and the charger unplugged, if it gets plugged in again, it doesnt charge, it just says "plugged in, not charging".
This is very frustating, and it makes me want to not use the laptop, which is not an option, as I need it.
Hopefully someone can help me!
Thanks in advance,
Matt

Here is a link to your notebook's support portal. Use the troubleshooting in the solve a problem section.
Did you ever calibrate your battery?
Chances are that your battery is no longer serviceable. Two to three years is a reasonable amount of service life for a Lion battery if it was never calibrated and/or has been left plugged in for extended periods of time. A battery that will not charge beyond 9% probably has issues.
Use the HP Support assistant to perform a battery status check. Also consider calibrating your battery. Calibration resets the 100% to the maximum actual battery capacity.
Best regards,
erico

HELP! laptop wont load past Welcome and warranty out

I have an HP Pavilion g6 with Windows 7 Home OS. I have no repair disc/install disk as I bought it brand new with the OS already installed and ready to use. I bought it in Fall 2011, so my warranty is out and I can't get help from Tech because they want to charge me just to talk to me over the phone without a warranty.
My laptop will load until the Welcome screen, and I have seen many posts already about this issue, however they are all able to load in Safe Mode and/or still have their warranty. I cannot load in Safe Mode. System Tune-up will not complete, stops halfway through as Failed, Startup and Run-in tests also fail. I already had problems back in March this year and had to restore to factory settings.
What boggles me most, is it was working fine until 2 a.m. this morning, when i stopped playing Fallout NV - was offline, have not connected it to internet for some months now. However, after the game I unplugged my laptop and took it upstairs and plugged it in in my room, and since then it hasn't worked. I can get to the boot options (Esc, F2, F8, F9, F10, F11, F12), but unable to do system repair due to no disc, and even though when I restored it to factory settings in March and made sure to do a Restore point at that time, the OS is not finding that restore point at all. It is not acknowledging any external hard drives I attach so I can do a new restore point. I don't want to just lose my photos - they are the only photos I have of my children (i think this is why most of us don't want to just restore to factory settings all over again).
Is there any way to do get it up and running again without losing literally EVERYTHING? I don't give a crap about the games or apps, those can all be installed from Steam later on again. But i don't want to lose my photos and baby vids and documents.
Thanks in advance,
Ree

Hi Ree,
Here are a couple of methods you could try to back-up your existing data.
1. One possible way to try and retrieve your files from a non-booting drive is to follow the process detailed in the link below. The Ubuntu operating system CD you create can run from the CD alone ( ie it doesn't have to install on the Hard Drive ) and I've often found it to be successful in retrieving data even from a failing Hard Drive. When you've created the CD, follow the instructions and see if you can back up your existing files.
http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windo...
2. Another option would be to remove the HDD, place it in an external caddy - an example is on the link below - connect this to another PC and see if you can access your files.
External HDD Caddy 2.5".

DP-K

Hp Laptop wont boot!

Hello! I had shut off my laptop to travel and when I tried to turn it on my laptop wouldn't boot up properly. My laptop would turn on and the HP logo would appear normally but after loading for a few moments an error would appear. "Your PC ran into a problem and needs to restart.... KERNEL_SECURITY_CHECK_FAILURE" The message would apear for about 3 seconds then would disapear back to the HP logo start up. It would then repeat. I tried these various teqniques and none of which have worked:1. Press f11 to get setup help.2. Press f2 to get a diagnosis3. Press f10 to make sure information is correct. My sister (Who has the same laptop model) had a very similar problem except she was able to reset her laptop and she didnt have the repeating pattern that I did. I would like to reset my laptop to factory settings as I do not have very many personal documents or items on the laptop. I am still under waranty for until about October and I also want to know if that would help anything. **Almost forgot, I didnt download any recent things and I cant get anywhere past the things i mentioned. I cannot get tothe login.** PLEASE HELP ASAP! I HAVE IMPORTANT THINGS TO GET TO!

Try removing a/c adapter and battery and then hold down the power on/off key for few seconds.
Also, if possible try accessing BIOS by pressing F10 key repeatedly.
If BIOS you can access BIOS then try using computer in VGA mode, by pressing F8 for advance boot options.
Also if you have any external monitor/display then try connecting it, so that video driver can be reinstalled.
You also mentioned about some stripes which shows some kind of damage to LCD, Please check on that as well
