HP G72 Not receiving power and not starting

Hi, so my G72 is not starting at all. Here's the backstory...i have been getting the internal battery message for a while at startup, approximately three weeks, and just ignoring it. We also had bad thunderstorms a couple of days ago and because of that our router was actually fried. My laptop was plugged in but not on. But, the weird thing is, my laptop worked for the next two days perfectly fine afterwards until i took it to my friend's house. There, when i plugged in, the charging light didn't appear. I moved to anothe outlet, still no dice, and actually i began to hear a high pitched beeping from my AC charger, the kind of beeping where you know somehting is wrong. Did a little research and came to the conclusion that it was toast, or at least not working like it should. SO we grabbed some other chargers that were rated for the same voltage and maH as mine, and tried them...after a couple minutes of trying them, we got my buddy's Dell charger to work, or at least make the charging light turn on. Thinking we fixed the problem, we took it out and put the other dell charger that was similar in, and again, the light wasn't coming on. After that, no matter what we did we could not get my laptop to get a charge light. I tried the hold power button down for a minute thing, and that didnt work either. I've ordered a new battery and charger, but now i don't think that will work either, and here's why...My mom has a g62, which uses a similar battery and charger. I plugged her battery into my laptop, no start up, even while using her charger, there was no charging light. This makes me think it is either the motherboard is dead, which would really upset me and may even deter me from buying another HP, or something is messed up with the AC jack on my laptop, which doesn't make too much sense saying as it worked PERFECTLY fine for 3 years until one day, which uasually those things get intermittent until they stop working. Any ideas or suggestions would be GREATLY appreciated, as i am willing to try anything if it means not spending anothe 800 bucks before i have to pay for school and car insurace and for the proposal I'm planning for my girlfriend. Thanks muchly.

Hello Soccermike,
I understand that your computer will not boot.
Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.
This should reset the hardware in the computer.
Also try to boot without the battery connected.
If you have tried other adapters it may be a problem with the board.
Make sure that the wire for the adapter is not loose.
Try to just wiggle the wire for the adapter inside the computer.
Let me know how everything goes.

I have a MacBook pro that has power issues and will not start but the hardrive is fine. I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one? Also, the software is not updated as the computer hasn't worked for about 2 months.
Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well? It is not saved in the cloud.
Thanks for your help, it is much appreciated.

You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

I just installed OS X Yosemite on my MacBook. I now cannot get the computer to start up. If I hold down the power button to try and power it back up, it will not start. Any ideas on how to fix this?

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and install the OS X Yosemite 10.10.3 Combo Update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:

Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X

My Mac Mini was not sending a signal to the monitor. I powered down using the power button and now it will not start. When i power up I get a strange 2 tone sound, like a warning alarm. The fan starts, and the light comes on, but no screen

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

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.

I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

After this Application pool is started but i am not able to communicate with IIS server through browser.
Please help any one to resolve this issue.

Update problem - will not start up, showing itunes logo and power cable

I tried to install the latest update this morning and now my iphone 5 will not start up. When I press the start button the apple logo appears then the screen shows an itunes logo and a picture of the power cable. I have started up itunes on my laptop and plugged the phone into it, but still the same problem.
Help!!!

That screen means it has entered recovery mode and you must use the recovery mode instructions in http://support.apple.com/kb/HT1808 to connect to a computer running iTunes. In summary:

Hey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

Because of low battery my iphone 5 got switched off and than its not starting by pressing the power button or by keeping it on charge. While charging a white screen comes for 2 second and goes away. This process continues till the phone is on charge. Please suggest how can I start my phone.

Hello Ritugor,
I would be concerned too if my iPhone was not powering on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Why will my iPad 2 not recognize any iPod cables? I have tried two different cables in both the wall and in my laptop, but it will not register that it is receiving power, nor will the laptop recognize that they are connected.

Crizzo is right, the best way to charge is with the included power block. That said, the USB cords are interchangable as far as an of us know. (just not power bricks, iPhone and iPod bricks put out 5W of power, the iPad wants 10W and will always say 'not charging' if plugged into less power than it requires even though it will charge, just very slowly)
If you have tried to charge your iPad - with the iPad charger - with multiple cables and multiple computers and get no joy then it's time to head to the apple store and have them check it out. The 30 pin USB port can go bad - mine did - and it's a manufacturer's defect (unless there's any sort of obvious damage) and should be covered under the warranty;

TECRA 9100 - power light flashes and will not start up system

my laptop will not start up - all I get when I push power on button is the power LED flashing the following sequence. S-S-S-S-L-L-L-S(S=SHORT, L= LONG)
DOES ANYONE KNOW WHAT THIS CODE INDICATES.
The only thing I might have done was to put a screw (b8 which is 12mm) into the network card locking switch slot on bottom of laptop that says MAX 4mm .
Any info would be appreciated to [email protected]

Hello
Unfortunately here is no public document about explanation of those hexadecimal codes and I can not tell you what it means exactly. The fact is that power supply electronic has detects some malfunction and sends code.
Sorry but I dont believe that you can do something alone. Try please to contact service partner in your country and explain them the situation.
