In my laptop Toshiba satellite L640, there are 2 issues
1] when I press on Power button it does not start OS I have to press any keys to start the OS.
2] When the battery is inserted in its slot and charger is connected, the battery does not charge in fact the status doesn not even change to Plugged in. But, when I remove the battery and turn the laptop on it works fine.
Can anyone please help me in these issues ?
the first issue,you can fix in the BIOS, you can set your PC to turn on by pressing any key on the keyboard, you have to remove this configuration and you're done, and the second problem, do not really understand, but i suppouse is a protection system.

I set my tango down for a couple of months while busy with other things. I charged it for a bit, turned it on and saw the red battery icon. I charged it overnight and saw the green battery symbol. I clicked the power button The splash screen came up, said it was installing updates and screen turned off. That evening I tried to turn it on and it wouldn't do anything. Next morning it turned on - splash screen - white screen, off. Now it doesn't do anything at all. I've tried - volume button and power, both volume buttons...nothing. Has anyone else had this problem? Any ideas? Thanks.

I have accidentally deleted the file System/Library/Extensions/IOStorageFamily.kext by mistake. I know how stupid this was!
Now my iMac (model 2008, running Mavericks) gets stuck on the grey startup screen and hangs forever after the Apple logo turns into a no entry sign whilst the wheel continues to turn forever, see the following link for image showing this screen:
No entry sign on startup screen
I have run Disk Utility from the install CD and repaired the disk permissions with no success.
I have tried to run the rescue partition by using the Command + R key but this just displays my exsisting HD and does not show another option.
I have tried to boot into single user start with no success. The screen eventually hangs and says it can not find IOStorageFamily.kext.
I have tried to boot into safe mode with no success. It simply fails with the no entry sign as above.
I have reset the PRAM but this did not make any difference.
I have done a hardware test using the D key on startup but this returned no errors.
Please can someone advise if there is any way to fix this problem and if the is then what is the best way to do it? I know that it is not a harddrive failing or anything else and is simply because I accidently deleted the IOStorageFamily.kext file. Surely there is a way to repair this?
I appreciate any help or advice.
Many thanks
I have managed to fix the problem by using the following method:
http://support.apple.com/kb/PH13842
It says:
If you have two Mac computers with FireWire or Thunderbolt ports, you
can connect them so that one of them appears as an external hard disk
on the other. This is called “target disk mode.”
Connect the two computers with a FireWire or Thunderbolt cable. Start
up the computer to be used as a disk in target disk mode: If the
computer is off, start it up while holding down the T key.
If the computer is on, choose Apple menu > System Preferences, click
Startup Disk, then click Target Disk Mode.
When the computer has started up, a disk icon appears on the desktop
of the other computer.
Transfer files by dragging them to and from the disk. Eject the disk
by dragging its icon to the Trash. While you drag, the Trash icon
changes to an Eject icon.
On the computer you used as a disk, push the power button to shut it
down, then disconnect the cable.
After connecting to another Mac I simply copied the deleted file back into the correct directory from the host Mac.
I then booted my Mac successfully and repaired the file permissions via Disk Utility.
I want to access BIOS on my ThinkPad x120e. I have tried to do it several ways like pressing F1 button for couple times, but it doesn't access the BIOS anyway.
How can I access the BIOS on ThinkPad x120e?
NOTE: I'm using Windows 7
Thanks.
As soon as you power on your computer, there should be a message that says "Press F1 to enter setup" or it might say "Press ESC to interrupt normal boot process". At this point, you should be prompted to enter the BIOS.
Needless to say that it doesn't matter what OS you have, bacause this process is OS indipendent. When you access BIOS, your OS is not even loaded yet.
I have a dual monitor setup,
1: a computer monitor connected via vga
2: a samsung lcd tv conntected via dvi->hdim cable
Until yesterday, this setup was working just fine. Today when I booted windows 7, the bios & windows loading ... screen shows up fine on my lcd tv
however, when windows loads and shows my desktop, my TV goes blank, and I only get the desktop on my computer monitor.
When I go to "screen resolution" and "detect", I only see my computer monitor listed.
As far as I know, no new display drivers were installed, I am using nvadia gt300.
Also, since the bios/welcome screen does show up on my TV, I can root out the tv/cable being faulty.
has anyone encountered something similar before ?
I had exactly the same problem. I de- and reinstalled drivers, I deinstalled the 11/18 Windows Update, I turned my monitor off and on again at least a dozen times as did I unplug and replug the HDMI cable - nothing worked.
Then, in an act of despair, I unplugged my monitor's power cable, replugged it and.... here we go again!
HTH!

Since I updated to OSX Lion I got a strange issue.
I am used to never shut down my Mac, I simply put it in hibernate / sleep mode.
But since the update to Lion the mac just starts up at random times.
Day and Night I can hear the CD-Drive sound when it wakes up.
The screen does not even go on, it stays black but the as soon as you hit any key the monitor just turns on.
This is really annoying as it sometimes wakes you up at night when you MAC is booting up.
I could not find a similar issue reported yet.
Thanks

Given the RTC (Alarm) wake reason, ensure Wake for network activity is turned off. See the last comment in the thread at https://discussions.apple.com/thread/3247367?start=0&tstart=0
Also ensure you have not scheduled wake. See http://osxdaily.com/2010/07/17/why-mac-wakes-from-sleep/
Launch the Terminal and type the following at the command line:
syslog |grep -i "Wake reason"
OHC: stands for Open Host Controller, is usually USB or Firewire. If you see OHC1 or OHC2 it is almost certainly an external USB keyboard or mouse that has woken up the machine.
EHC: standing for Enhanced Host Controller, is another USB interface, but can also be wireless devices and bluetooth since they are also on the USB bus of a Mac.
USB: a USB device woke the machine up
LID0: this is literally the lid of your MacBook or MacBook Pro, when you open the lid the machine wakes up from sleep.
PWRB: PWRB stands for Power Button, which is the physical power button on your Mac
RTC: Real Time Clock Alarm, is generally from wake-on-demand services like when you schedule sleep and wake on a Mac via the Energy Saver control panel. It can also be from launchd setting, user applications, backups, and other scheduled events.
Hope this fixes your problem.
