T400 power light indicator is on, but nothing else is

Hi,
Every once in a while when I turn on my laptop, it powers on but the monitor doesn't seem to boot up. The power light indicator is on and everything else sounds like it's running, but the monitor doesn't turn on and no beeps occur.
I tried running diagnostics and nothing wrong was found. Lenovo customer support couldn't help me.

Satalite Pro Power lights come on but nothing else ??

Hello All,
A quick question. Have been given a Satalite Pro. The Power lights up but nothing else.
I've tried the HDD in my Portege m200 and its running XP Pro. The Satalite Pro has 1 > 512 ram stick inside.
The overall condition is good and i'm tempted to spend a few shillings to try and bring it back to life or are we talking major surgery.
My knowledge is basic so would have to pass on to get fixed.
Would welcome your thoughts / suggestions.
Thanks
Neil

Hi
I dont know which Satellite Pro you have exactly but if your Portege M200 uses the same RAM modules, you should try this to exchange them. Sometimes the notebook doesnt start due faulty RAM modules. They are exchanged in few minutes and not expensive.
I doubt that the HDD would be the problem. If the HDD doesnt work, you able to access the BIOS at least.
In worst case its related to other expensive parts like CPU or mainboard. :(

When I power up my mac, I see the white screen and the apple icon. After a few seconds of powering up the screen goes dark. Yet I still can the mouse arrow but nothing else.

When I power up my Imac, I see the white screen and the apple icon. After a few seconds the screen goes dark. I am able to still see the mouse arrow as I move it around. But nothing else. What is the problem and how do I recover?

Try this from another user:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).

My apple tv stopped working. When I hit a button on the remote I see the signal gets to the Apple TV because the little light flicks but nothing else happens. Anyone know how to fix this??

My Apple TV suddenly stopped working. When I hit a button on the remote the light on the apple tv flickers but nothing else happens. Anyone know how I can fix this?

I had the same problem; Apple TV was working proper then for no reason I got the continuous blinking front LED. The Apple TV has no sound or video output at all. I tried reseting the Apple TV via my Apple remote controller but that didn't do anything for me. I finally called Apple and they told me that the way to fix my box is to reset the Apple TV to factory default. So I had to attach the Apple TV to one of my Apple computers and launch iTunes. Once iTunes was running it recognized my Apple TV and I clicked on the option to restore to factory default. After the restore my Apple TV now works properly. My final action on the Apple TV was to sign into my account and enter my password.

Do you have a question? This is a user to user help forum. Apple is not here only other users like yourself. You don't report problems to Apple here.

Pior to doing that I pulled the power cord and reset my networks... and still noting, please help....

Welcome to the Apple Community.
Yes there are quite a few similar reports at the moment, I haven't experienced the problem, yet others in the UK have, so we're not quite sure what criteria determines whether you are affected by this. I haven't seen any solutions so far, so it may just be a case of waiting to see if it's repaired or whether the rest of us are going to see the same thing.

Ok, tried message boards everywhere to try and figure this out before having to post a question. Have a 21.5" iMac running Snow Leopard 10.6.8. After updates no wireless capability for ipad or laptop, imac connects fine but nothing else.No widgets work.

Your post is pretty lengthy and I have to admit I didn't read it all. Please try restarting in Safe Mode, if that doesn't work please do both a SMC and PRAM reset. These may take 2-3 attempts.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

At App Store I see that Facebook needs updating. However, when I click on "update" the blue circle appears but nothing else happens.

At App Store I see that Facebook needs updating. However, when I click on "update" the blue circle appears but nothing else happens.

The blue circle should go around, clockwise, as a fine line, and then as a heavy line indicating it is downloading. Then it sits while the install takes place. It may sit and wait to start the download if the internet connection is slow.

Hard disk turns on but nothing else

Hello, I'm a teacher running a lab full iMacs and I have one giving me problems. When I press the power button I can here the hard disk (or something inside) start running but nothing else happens; no start up tone, no display, nothing. So far I have tried putting the install disk in and holding "C" but this gave me zero response and now the disk won't eject. I have, if I am remembering the terms correct, tried reseting the the SMU and SMC and still got nowhere. Any help someone can give me would be greatly appreciated!
God bless!

Run the cleaner tool and reinstall with sufficient user privileges and security stuff turned off. Your install went wrong because you didn't consider this.

My first gen 3g iphone photos are not recognised by camera wizard - it sees the phone but nothing else no files - it is not locked - ?

I have a new 4g Iphone - Telstra (Australia) disabled my old 3g and enabled the 4g so the 3g is just enabled to show contacts and photos etc.
I want to download my photos and contacts from the 3g. trouble is that my internet is dial up only at home and impossible to use as too slow.
So my itunes is now out of date (not current module 10.5 + etc.) and the 3g phone is also not operating on the latest ios.
BUT the itunes does sync the phone - but it seems to only sync from computer to phone - so my camera roll on the 3g is not on my computer - therein lies the dilemma - I don't know how to download the photos. I cannot update the ios on the 3g and it seems that might be reqired to "back up"
So first question is how do I back up (not sync) my 3g to itunes.
Do I need to updates its ios first and update iteuns first (in which case thats impossible)
So what else could I do.
It seems the other thing is that even if I could back up the 3g the Itunes won't recognise the 4g as the 4g is ios 4 or something and the itunes is not up to date.
SO I thought I should just use camera wizard or a photo package like iphoto or kodak easy share.
But with camera wizard my computer recognises the 3g phone BUT nothing else. It is greyed out for options, and ini Windoes Explorer it shows it as a camera but when you right click it has no "properties" - and no files show up at all...
it is like it seems the camera and then nothing else.
THE CAMERA is not locked.
WHAT shoudl I do?

also - when I use camera wizard it just tells me the phone is busy or in use and I should retry.
If I use it through windoes explorer - it shows me the camera to computer symbols and a line moving between then but bombs out saying camera is busy.

ACE 4710: Possible to allow a user to clear counters but nothing else?

Hello all,
Using an ACE 4710 we have a user setup with the Network-Monitor role which allows the user to view config, interface status, etc. We would also like to allow this user to clear the interface error counters as well, but nothing else. Is this possible?
Thanks!

Hello Brandon-
Network-Monitor only lets you browse outputs, it is a not a role that allows a user to make any changes including clearing stats. You can create custom roles and domains to get closer to what you want, but you cannot zero in on a single command like that.
i.e.
ACE# conif t
ACE(config)# role MyRole
ACE(config-role)# rule 1 permit modify feature ?
AAA             AAA related commands
access-list     ACL related commands
connection      TCP/UDP related commands
fault-tolerant Fault tolerance related commands
inspect         Appln inspection related commands
interface       Interface related commands
loadbalance     Loadbalancing policy and class commands
pki             PKI related commands
probe           Health probe related commands
rserver         Real server related commands
serverfarm      Serverfarm related commands
ssl             SSL related commands
sticky          Sticky related commands
vip             Virtual server related commands
You can create a permit or deny rule, within that, create/debug/modify/monitor each feature seperately.
Domains allow you to create containers for objects. You can place specific rservers, serverfarms, etc. into it - then apply it to a role so that the user assigned to it can only touch those objects.

I can print a test page from my Mac to my HP Officejet Pro 8600 but nothing else will print

Hi - I just recently had a hard drive crash and had to revert to an old Time Machine backup on my new hard drive to get my Mac back. Since getting back up and running I have been unable to get my Officejet Pro 8600 back online. My computer is wired to the wireless router but the printer is running wireless. My computer can see the printer just fine and I can even print a "Print Quality Diagnostic" report from my Mac to the printer from the HP utility. But nothing else will print. The firmware is up to date. I have tried resetting the printing system multiple times, rebooting the machine, etc... Nothing works. Any help would be appreciated.
If it helps, we were using a different printer the last time the time machine was backed up, so when we used that backup the old printer was showing, but I reset the printing system, so it shouldn't matter.
Thanks for your help!

Hello @Ryan221,
Welcome to the HP Support Forums! I see your hard drive recently crashed and now you are not longer able to print to your HP Officejet Pro 8600. I see you have reset the printing system with no success. Let's try a different approach:
Scrub/ Uninstall
• Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
• Click continue, click on one of the printers in the list.
• * Only do this step if you do not have any other HP Printers. Hold down Control, Option and Command, While holding the three buttons down,
• Click uninstall.
Reset Printing System
1. Click the Apple icon ( ), and then click System Preferences.
2. In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
3. Right-click (or Ctrl +click) in the left panel, and then click Reset printing system…
4. Click OK to confirm the reset.
5. Type the correct Name and Password.
6. Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol..
Repair Disk Permissions
1.On the Dock, click Applications, and then click Utilities.
2.Double-click Disk Utility.
3.Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
4.Click the Repair Disk Permissions button at the bottom of the window.
5.Once the repair is complete, restart the computer.
Restart the printer. Now you can download and install the printer software and install it. Click on the link below to begin the download and follow the on screen instructions:
HP Officejet Pro Full Feature Software and Driver - Mac OS X 10.6, OS X 10.7, OS X 10.8
I hope this helps, please let me know the outcome!
