Does it hurt to clear CMOS without the power completely disconnected?

I noticed in this thread https://forum-en.msi.com/index.php?topic=31222.0 that it says to completely remove all power before clearing CMOS. all the user guide said was that the system needs to be powered off so to me that simply meant just turned off.
I have cleared my CMOS twice but both times it was not unplugged but simply turned off so did I risk damaging anything?

No it shouldn't damage anything it's just that at times some people seem to be unable to get CMOS cleared by simply turning system off and switching jumper/pushing clear CMOS button and it's recommended to pull the plug or if PSU has an on/off switch turn it off 1st.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?

Please take the Mac to Apple store to have it checked out.

Envy DV7 laptop will not boot without the power cord being connected

My laptop won't boot on its own even when the battery indicator reads "fully charged (97%). If I have the power cord plugged into the computer (and the wall), it boots right away. Without the power cord, the "power indicator light" flashes once, the screen brightens to a lighter shade of gray, then it just shuts down.
I'm thinking I need to replace the battery but I thought it best to check with the experts first...................☺
Thanks!!
ETA..........I just saw the post about power cord failure. My power cord is one of those affected and I will be filling out the request for a replacement. Unfortunately my serial number is apparently located inside the battery compartment. I'm wondering if my cord has overheated and caused this boot problem with my computer.

Hello, @jksweeney
Welcome to the HP Forums.
I see that your having an issue with the power and your notebook. That you've applied to have the power cord replaced as it was part of the recall.
Please let me know when that has been taken care of if the issue remains. I will remain subscribe to this thread, so that I will be notified if you post again.
Thank you for posting on the HP Forums.

Iv'e tried C-F2 also. has anyone used this devive (AV360) on there own 27" thunderbolt display (not the imac) and gotten it to work? If so I'd appreciate the help.

There are multiple reasons that lead to issue. You should read the troubleshooting guide to get the right solution to solve the issue: iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support

I am having trouble with my iPad, i can start it, but the iPad does not work. i tried to use the power and home button at the same time, the apple logo appears, but the iPad does not work. What am I suppose to do?

After the Apple logo appears, what happens then? Can you hear any sounds or if you tap on the screen, does it seem like apps can open or are you just seeing a black screen? You might have a hardware problem, but you can try restoring the software and see what happens.

W500: using the switchable graphics with vista ultimate without the power manager software?

seriously, invest in a new hitachi travelstar 320gb for 49 bucks from that tiger place online and a usb hard drive caddy, pop in your free clonezilla cd and your rescue and recovery problems will be over!
after reading all the problems with that software i figured my data was too valuble to get caught in that mess so for under 75 bucks problem solved and i rid my w500 of that bloatware. even cheaper then ordering the recovery disks from lenovo.
working on getting rid of the rest of the useless software now.
hey question, how do you use the switchable graphics on the w500 with vista ultimate without the power manager software? if you can thats next!!

That's because you are asking a T500/W500 question in the Thinkvantage forum. Anyway, the answer to your question is in this thread.
ATI recently started packaging their switchable graphics driver together with their regular Catalyst. So downloading their latest driver Catalyst 9.4 from the ATI/AMD site and then modifying it with the Mobility Modder will allow you to use switchable graphics without the power manager. The little problem is just that the released version of the Mobility Modder stopped working with Catalyst 9.2 and you are on your own getting a modified Modder working on 9.4, see here.
So I decided not to make more work for myself staying on a modded Catalyst 9.1 and for the time being living without switchable graphics.

My Macbook won't turn on without the power lead in!

So yeah.. basically what it says, one day everything was fine and then the next day I tried to turn it on and it just wouldn't start without it being plugged into the power so I did all the classics and took the battery out and made sure everything looked right and stuff but still nothing without the power lead in!
It's not even liked I have changed anything major-ly. I mean the only thing I've changed is that I've started playing on Starcraft again, which I used to do (don't judge me!) and that seems to have changed something, it might be unrelated, I don't know!
The weird thing though is that it works fine with the lead in until I take it out and then it just turns off. oh and it will sleep with the power lead out but that's all.
Can you help at all?!

You probably have battery update 1.3 installed unless you fixed it already. See if you have battery update 1.3 installed. It seems to be installed when you update to 10.4.11. You can find it here.
MacBook/Library/System/Library/SystemConfiguration/BatteryUpdater.bundle
Use get info to check. It is the MacBook Pro update. If it is 1.3 drag it to the trash and then reboot. After you reboot you will be able to emtpy the trash. Once you have done that run software update and it should install Battery Update 1.2. You should also reset the SMC (System Management Controller).
Also the only battery that Apple extended the warranty on is the original core duo batteries. This is from the 1.2 update notice.
+For MacBook and MacBook Pro systems with Intel Core Duo processors, this program extends repair coverage on the battery for up to two years from the date of purchase of the computer.+

Does turning off your MacBook by holding the power button hurt your MacBook

Almost whenever I exit out of War Craft 3: The Frozen Throne my Mac Book freezes up, as a result I frequently turn off my Mac Book by holding down the power button- Does this hurt my Mac Book?

There is most definitely a chance that you can cause stability problems (although, it is somewhat less likely that you would cause any harm to the hardware). The likelihood of you causing problems increases directly with how often you shut down this way. You should be seeking a solution to the issue you are having with WC3. As Johathan mentioned, OS X does quite a bit in it's shutdown process. Bypassing that can cause anything from basic data corruption, to stability issues, to a non-bootable system depending on what the machine is in the middle of doing when you force it to shut down. In general, worst case scenario is that you would need to re-install OS X to fix things up. It's really not worth taking a chance on your systems stability for the sake of a game. I would say that you really should try to track down a solution to the problem you are having with the game.

Does Apple host business web pages without the OSX Server?

Does anyone know if Apple hosts business web pages other than what you would get with the iWeb app and MobileMe without the OSX Server?

I would suggest using a third party hosting service "I use IX Web Hosting. MobileMe simply does a domain mask. IX Web Hosting offers reasonable pricing, unlimited bandwidth, & dedicated IP addresses just to name a couple features.

Clear CMOS - without moving jumper/pins

Thinking about trying to OC my 3000+(W)@Neo2.
My case and eq. in genreall makes it hard to clear CMOS the "old way", and I remember someone telling of a keystroke one could do under reboot to clear CMOS.
How can I do this on the Neo2 and what are the dissadvantages?

If "Ins" Key is held down when powering up , system starts with reduced fsb and other safe settings . Making that clear cmos jumper uneccesary when OC has gone bad.
Note ! It must be powered off and powered on with the key pressed (just restart key + "ins" wont work).

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.

HT3131 how can i run in clamshell without the power adapter plugged in?

just what the question states..I dont want to have to always connect the power adapter. thanks

thanks this works well with the power adapter pluged into the mac, but I am looking for this exact setup without the need for the power to be supplied to the mac.
in otherwords, run it off the battery only.
I want to think that there is either a preferences setting, or function to be able to do this.
currently it appears that the mac will only run in the configuration with external perpherials with the power supply.

Hi, my iphone 4 home screen keeps flashing on and off repeatedly. if I'm using my phone or in an app it will just go black then light up to the home screen and it does this over and over. Then the power off option will pop up. what should i do

Hi my iphone 4 home screen keeps flashing on and off repeatdly. I will beonmy phone or in an app and it will go to a black screen and then light up to the home screen. Then the power off option will pop up. I have tried letting it die and recharging it and powering it off neither worked. Does any one have an idea on what this could be or what I can do?

If the Slide to Power Off option is coming up, that suggests your power button isn't working correctly and is sticking.
Best thing to do is bring the phone to an Apple store (make an appointment first) and have a Genius take a look at it.
