System will not power up at all AC power light only G50-109NR
Hell,
I have a HP G50-109NR that has had the following parts replaced up to this point.:
System Board
Power On Assembly Board
Plug In Type DC Power Jack
I get the light next to the power jack to come on when I plug the power supply in.
That is all I can get to happen on this laptop. I don't want to give up, it seams to me like it is still not getting power but yet the little light next to the plug lights up. I have checked the output of the power supply and it seems to be working. I mean not a beep no other lights come on nothing. This time the system board came directly from HP. I have used very good anti static protection through the process. Anti static mats my self and even my hand tools are grounded together.
Please anyone that has any Ideas at all please contact me via my email [text removed for privacy]
Thank You for any help received.
Have you tested the polarity, voltage, amperage and such coming out of the power brick? There is definately power coming out of it, but LEDs, as I'm sure you know, will light up with a lot of power specs, including what may be out of range for the motherboard to power on with.
I take it the battery is completely discharged? I have owned several second hand laptops that have had issues with batteries. One, the battery was toasted, and if it was in the laptop, it wouldn't power up regardless of the DC input. The one I'm using now won't power on unless the battery /is/ installed, though the lights come on. Maybe you have a similar situation there.
I'd still consider stripping everything non-essential off the motherboard to try.

For a few weeks now, I've been getting the "Bookmarks and history system will not be functional..." message. When I clicked for more information, FireFox would freeze.
I found a solution about a new places database, but for the past few days I can't get FireFox to open at all. Then my whole system is frozen and I have to turn it off to get it going again, thus losing a lot of unsaved data.
How can I get FireFox back?A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine. -
My MacBook Pro will not powerup (even when connected to power supply).
My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.
Hi PatB11902,
Thank you for visiting Apple Support Communities.
If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
There are several steps that can help troubleshoot this behavior, found at this link:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Start with these steps:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Start up in Safe Mode.
If your Mac does not start up normally after these steps, here are some additional tips that can help:
Troubleshooting: My computer won't turn on - Apple Support
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

I am using an older windows computer with Windows XP and iTunes 11.0.5.5. Since upgrading my iPhone and iPad my system will not allow me to connect the devices to my iTunes -- it notes I need to upgrade to iTunes 11.5. However using automatic updates or manual update I can not update iTunes -- I get an error message the older windows iTunes could not be removed. I can not remove iTunes using control panel -- an older install/uninstall file is evidently missing. All of my music is contained on my PC -- more music is on my PC than I store on my other devices and I don't want to loose those music files nor permission to access those music files. Does anyone have a solution to uninstalling and upgrading windows iTunes without losing my music. I would like to be able to connect my iPhone and iPad to my PC again. RS

System will not boot with Seagate 3Tb expansion drive plugged in.
I have a HP Pavilion HPE h8- 1214 Desktop , I recieved a Seagate 3TB expasion drive as a gift but when plugged in, the system will not boot. It turns on but thats it. It never gets to the boot sequence. I have it plugged into the top 3.0 usb slot and have tried all of the other slots as well with no sucess. But if I leave it unplugged the system boots right up. I can then plug it in and it works fine. I have plugged it into my wifes HP All- In- One and it boots fine and works. I have a WD 2TB drive that works fine as well on my system . I have searched Segates support for hours and all they say is to change the boot sequence. Have tried that, no go. What they dont get is no matter what I do if that drive is plugged in it never gets as far as booting and reading the boot sequence. Please help. Thank you!
Hi NcBunky,
Are you using Win 7 64 bit? Did you update the Texas Instruments (TI) USB 3.0 XHCI Host Controller?
I have an H8 1380t PC. Updated the TI USB 3.0 driver and had the same problem.
When booting the PC with the USB 3.0 external drive connected to the PC the PC would not boot. When booting the PC with only the mouse, keyboard, and a USB 2.0 external drive attached the PC would boot. Once booted you could attach the USB 3.0 drive and it worked fine.
Solution was to roll back (reinstall) the TI USB 3.0 XHCI Host Controller to the original factory installed driver.
System now boots with the external USB 3.0 drive attached.

I have Windows 8 pro on my computer . I un-installed itunes on my computer to re-install itunes 7.1.1 Now the system will not allow the re-install. Can anyone help?
I have an HP Officejet Pro 7580 similar to the 8600 you have and after upgrading to Mountain Lion it wouldn't work. HP support site said download updates for Mountain Lion from App Store not their site so I went to software update but there were NO UPDATES FOR 10.8. Tried a million things and could not get printer to work. So I restored back to Lion figuring at least printer worked then only now I can't get it to work with old settings either. I am sick to death of claims by Apple and peripheral manufacturers that everything is compatible all you have to do is get updates well in this case THERE ARE NONE TO BE GOT and I don't have time to **** about trying to find 'work arounds'. There shouldnt be a need for work-arounds. Unless the updates are ready DONT release the new OS. You shouldn't have to be an IT tech to make basic things like printing work. I see also the HP 8600 is even sold by appstore so there is no reason why it shouldn't work with minimum fuss.

My iphoto will not open correctly. All I get is the little wheel going around and around. What do I need to do to fix this? I would like to be able to see my photos again.
There are 9 different versions of iPhoto and they run on 9 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have. -
Order types entered in a Ztable, system will not perform material listing.
Hi Guys,
I have a requirement where user will enter the list of order types to be excluded from material listing through a custom table.
For all those order types entered in the custom table the system will not perform any material listing check, regardless if the material is existing in the material listing.
Can you please tell me how to do this through coding???Any particular exit or where can i code this.???
Many Thanks in Advance,
Rajendra

Edited by: Vinod Kumar on Jan 13, 2012 4:08 PMSwagat,
Thank you for your response, what I am still not getting is - even in manual transfers via LT10 shouldn't the system restrict the movements to certain storage types? If you think from the shopfloor perspective the WM material movements are done at WM level only - meaning moving materials from one storage type to another and LT10 is widely used as it is one step tcode.
I know we can restrict movements when storage class is assigned in search strategy, but this applies only to hazardous materials. The material in question is not hazardous so I am still thinking if there is any way to restrict material movements.
Do you have any documentation link which mentions search strategies are not taken into consideration during manual transfer? If yes please send that would be helpful.
Once again thanks for your time. -
I've installed Mavericks on my Mac Pro. It works well, generally, but will not stay asleep! Pressing the power button twice sometimes extends the sleep mode but even that seldom results in a full overnight sleep. File sharing off. What else can help?
Hi fremley,
Thanks for visiting Apple Support Communities.
This article may be helpful with determining why your Mac Pro doesn't stay in sleep mode:
Mac OS X: Why your Mac might not sleep or stay in sleep mode
http://support.apple.com/kb/HT1776
Some things reset the sleep timers, preventing the computer from sleeping:
Hard drive access (even if you're not using the computer, a running application might be accessing your drive, such as when downloading a large file or listening to music in iTunes)
Moving the mouse or using a portable Mac's trackpad, pressing a mouse button, or pressing a key on the keyboard
Some System Preferences settings (see below)
Open applications (see below)
Input devices (see below)
Expansion cards (see below)
Additional drives, such as USB, FireWire, DVD, or CD drives (see below)

Installing an older version exposes your system to attack as described in this Adobe security advisory: http://blogs.adobe.com/psirt/2011/09/security-update-available-for-adobe-flash-player-apsb 11-26.html
If all you want to do is watch videos on Youtube, you don't need Flash and can watch them in HTML5 instead. All you need to do is to install Firefox which supports WebM. Firefox will run on most systems without a problem: http://www.mozilla.org/en-US/firefox/8.0/system-requirements/ (download link on the same page).
