NB-100 No Display with Power

I have NB-100 notebook, recently it hangs up with white screen after 10 minutes I open, then the worst came...
There is no display but with power. the hard disk led and the power led is steady.
Can please somebody help me with this problem? Thank you very much and God bless you all!

Which NB 100? What is the part number? Which country?
Which Windows?

    Is it possible to run a 30" Apple Display with a Power Book G4 Laptop

    yes with either this or that.

  • 23" Studio Display with Power Book (17")

    I am considering running a 23" studio display with my 17" PB. From perusing the discussions here it seems this is entirely possible (although there is some debate over keeping the clam shell closed during operation...). As a photographer and heavy user of Photoshop my concern is this: will I get full perfromance from the 23" in this configuration...will it perform to the extent that it would if connected to a current desktop Mac. Also....will adding a studio display to the PB diminish its performance in any way, either with its own screen on or off? For your information, the PB is relatively new; purchased within the last year. Also, if there are any Photoshop users out there: is it possible to set up the smaller 17" screen for things like palettes etc., and reserve the 23" for the image being edited, only? Thanks.

    It's plug and play, so that's not an issue.
    The debate about running the clamshell closed is so that, if the extra desktop space is not required, there is no point "stressing" the video ram and videocard and cpu by having the other display running - all resources can turn to the external display.
    As for extending the desktop, yes you can do that with Photoshop - you have the space of the PB and the new display, entirely up to you what you put where - just drag across.
    Performance wise, I don't imagine that Photoshop would cause as many difficulties as say video editing might, and I've not come across anyone saying that they have had performance issues from running the extra display - you may get some extra heat as the processor is taxed though.
    If in doubt, you could test at an Apple Store or reseller.
    Also, you might find getting extra ram a useful upgrade.
    Hope that helps, best of luck.

  • 27" LED Display with power issues

    I have had some peculiar issues with my ACD since I received it about a month and a half ago. I use it with my new i7 iMac. Specifically, the issue is with the power supply inside the unit (I think). One night about a month ago, I heard a "pop" from behind the ACD, and it went black. I knew that the unit itself was fully powered down as I could get nothing from any of the USB ports (such as charging of my iPod). I swapped power cables with my iMac, and the iMac powered on just fine, so I ruled that out. I then left the unit unplugged, boxed it up, and took it to the Apple Store the day after. To my surprise, it powered up just fine when I got there. Sure enough, it worked again when I brought it back home.
    Now, just last night, I switched off the breaker panel to the circuit that had the ACD on it to change a light fixture. When I turned it back on, I powered back up my iMac...and the ACD did not turn on. Same thing: all ports dead, no power at all. Left it unplugged for 2 hours...no results. Then, I left it unplugged over the entire night. When I woke up, plugged it back in , and now it works again.
    It seems as if the longer amount of time allows the power supply inside to "reset" somehow or something, but I am at a loss as to if this is some sort of true defect, or a flaw in design. Even the instruction manual recommends leaving the unit unplugged for a while if it fails to power on.
    Anyone have similar issues? Anyone able to help me figure out what is going on?

    What I do when I have issues that can be tough to replicate is record them with my phone, take the unit to the store, and if it doesn't happen, show them the video.

  • HT204154 My macbook with thunderbolt display without power supply stops working on battery mode, is that normal?

    I use a 27" Thunderbolt display on my macbook pro. If I disconnect the power supply from the mac, the monitor stops working.
    Is that normal or do I have to make some changes on the setup ?
    Thanks
    +GL

    Greetings koningsvaren,
    Welcome to the Apple Support Communities!
    I understand that you connect your MacBook Pro to an external Thunderbolt display and everything works as it should while connected to power, but once power is removed from the MacBook Pro, the second display no longer functions. It sounds like you may be using this configuration with your MacBook Pro closed, otherwise known as closed-clamshell mode. In order to use a second display with your Mac portable in closed-clamshell mode, the Mac portable must be connected to power. Please refer to the attached article for more information. If this is not the case, please let me know.

  • Powering down display with external power supply

    I am using a 23" display with an old PowerMac G4 from 1998 with an upgraded video card and external power supply.
    Is there any way to power off the monitor without powering down the computer? Ideally I'd like this to happen automatically based on my system prefs, but apparently the external power supply precludes this.
    As a "workaround", I've created a screen saver that displays a black image. Does this actually save any energy and/or extend the life of my display?
    Thanks,
    - Michael

    Hi Michael,
    Welcome to the discussions.
    You can install an on-off switch on the power lead to the external power supply (actually, it's safer to have a qualified electrician do this, as you are dealing with a mains power supply). I have this system for my ADC 15" Display, and it works fine.
    A black screen saver will not extend the life of your monitor. Screen savers were meant to mitigate the "burn in" effect that happens with CRT displays (and which doesn't happen with LCD displays). If the display is still on, the backlights will still be functioning and they are the finite life component of the LCD display that you need to look after. Also, because the LCD's themselves use so little energy, there will not be much energy saving.
    It's more appropriate to "sleep" the display. You can do this (via Energy saver settings in System Preferences) without having to "sleep" the entire computer. This will turn off the backlights and significantly extend the life of the display.
    (I'm presuming you are using OS X - you haven't supplied any details regarding your system. :))
    Cheers!

  • Acrylic 20" Cinema Display with new MacPro

    As I read the posts here, to use the old cinema display with an ADC connector I will need to buy Apple DVI to ADC adapter to connect my 20" cinema display with ADC to the new MacPro?
    This new DVI to ADC adapter provides power for the cinema display as I understand which is why it's so expensive whereas when cinema display was connected to my Powermac G5 the power came thru the ADC connection?
    Is this correct?

  • Need to connect an Apple Display with an ADC plug to a Mac Mini with a DVI port

    I have an older Mac Mini (I'd guess at least 4-5 years old, but I have a terrible memory), and I want to connect a Cinema HD Display with an ADC connector plug. Unfortunately, my Mini only has a DVI port, and I cannot find an Apple adapter, or any adapter for that matter, under 200 dollars, which is an absurd price to simply connect one slightly different plug to another. If a $200 adapter is really the only option, then I will find a different monitor, but I would prefer to connect this one, as it is the most convenient option.

    It is far more than a matter of different plugs. The signalling schemes are completely different and it also has to act as an external power supply for the screen. This screen was originally designed to get power from a PowerMac computer.
    I found a genuine adapter on Amazon see http://www.amazon.com/Apple-M8661LL-Display-Adapter-4038234011420/dp/B00011KHT2 at $119 but other than that you could look on eBay for a used one.
    You are right to consider whether it is worth paying more for a brand new screen rather than trying to extend the life of this old screen. Be aware that if you want to try using Apple's latest 27" ThunderBolt screen you cannot directly connect that to your old Mac mini but could do so by (you guessed it) buying another expensive adapter. In this case you would need an adapter from Kanex see http://www.kanexlive.com/c247dl
    You can of course use virtually any standard (non Apple) DVI display.

  • I have a macbook pro 15" Retina Display with 2.6 ghz and 8gb of ram yet when i try to download a HD movie from itunes it says my computer doesn't support HD?

    i have a macbook pro 15" retina Display with 2.6 ghz and 8gb of ram when i try to download an HD movie from itunes it says my computer doesn't support HD? i went to the support on the apple website and looked at the specs that a computer has to meet in order to play HD movies and mine is well above them. Why can't i play the movies?

    That would at least partially explain it.
    These MacBook Pros drew more power than the power brick could readily supply, and so would only run at top speed when the power brick was supplemented by the battery.
    Though the applicable tech note has been removed, it stated:
    "If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide."

  • External display with MacBook Pro in Lion

    Hello,
       Yesterday I bought a Mac OS X Lion, and I found one annoying feature of the system - working on a MacBook Pro (MBP), and very often use an external display, with that do not use display in the MBP. When connecting an external monitor doing video processing,and this activity I was used by Mac OS X Snow Leopard to open the MBP there wasaccess of air to cool the computer. After installing the Lion was the fact that even at very small opening MBP is switched to internal MBP display. This is the functionality of the Lion off somewhere or somehow set? I looked in Preferences, and I have found nothing. Thank you in advance for information on how to solve this problem.

    I own a mac mini that stays connected to the 52" LCD 120hz in my living room. The image is perfect, and fits just fine. I did a mini-display port to dvi and got a monster cable adapter for dvi to hdmi which too it to my tv. I did have to go into the tv and set the tv to overscan I think on the image to make it fit and you will have to adjust the resolution on the computer. I can say the colors are darker on the tv and this is just due to the nature of the screen size. Newer LED tvs may be better, but mine is only 1 1/2 years old.
    For an external display, just go to the educators link, select your college and you get $100 off. My wife is an educator and I am back in college so it's no hassle. Or they just ask for an ID. I own 2 24" ACD and they are nice. I do photography and a screen calibration is a must. Once done you'll be happy. And docking with the laptop is handy.

  • Can I connect my thunderbolt display's power cable to supply power to the new retina display macbook pro?

    I'm planning to buy a new retina display macbook pro, but I have a thunderbolt display and I use the display's power cable to supply the power to a macbook air. As the power connector on the new macbook pro is differet, It looks to me that I won't be able to connect it to the new computer. I'm I correct?

    You'll just need this adapter, which you can buy or order with the computer:

  • Sharing Cinema display with a PC

    Is there a way to share (via a swith box) my 20" cinema display with a PC. I know that there are DVI switchers but do they support the fact that the MAC display is powered through the connector interface aand that the firewire and usb is on the same connector as well???
    Thanks

    The DVI connector does not carry the power to the display. The cable from the display carries the power, USB, FireWire, and digital signals. At the computer end it is split into separate cables with plugs for USB, FireWire, power and DVI.. The switch would go between this DVI plug and the DVI connector on the computer's video card. The power would not go though the switch. The fancier switches will also have sockets to switch the UBS as well, so a keyboard and mouse plugged into the display will switch to the computer using it. This will also allow computer control of the display brightness.

  • Early (Jan.04) Cinema 20" display with ADC:

    Need to replace video card in G5 (Jan 04). Need video card with ADC. Any suggestions as to where to purchase this. Tried DV Warehouse already. To expensive for refurbished card. Can I get around the ADC on new video card.

    The Mac Pro features one DVI-I, to which you can attach your DVI-display-with-powerbrick-in-cable, and two Mini DisplayPort.
    ATI has moved forward smartly into Mini DisplayPort, nearly shortchanging users of what they call "legacy" Interfaces such as DVI, HDMI, and VGA. In order to run Three legacy Interfaces, ACTIVE (read Powered) adapters are REQUIRED.
    What appears to be happening is that "the simulation of DVI" provided is a little short on power. If you don't run the ACTIVE adapters that include an additional USB for still more power, you can't run three.
    Some users have reported that passive adapters used for ANY DVI displays are having sporadic trouble. The low-cost ACTIVE Adapters contain signal Drivers that use an internal power lead. The pricey Dual-Link adapters need two sets of Driver circuits, and go to an external USB cord to pick up still more power to run them.
    Executive summary: There may be sporadic problems with signal levels for certain displays. If an adapter is needed, an ACTIVE DVI adapter is recommended.
    If running three DVI displays, ACTIVE Adapters that also include an extra USB cord are REQUIRED.
