T42 (2374-E88) - Wont Power Up

A friend asked me to see if I could get his Type 2374-E88 T42 working. It had not been used in a few years and had neither a port replicator nor a power adapter. I purchased a power adaptor, confirmed it is providing the required 16v output, but there is no response from the machine when I press the power button. I tried removing the battery, hard drive and RAM, waiting 30 seconds, reinstalling the RAM, reconnecting the power adapter and trying again with the same lack of response.
I fear it is a system board problem but wanted to poll you experts to see if there might be some other steps I could take to confirm that. If it is the system board, I'm up to trying to replace it if I can get one for under $200 but first have to figure out what the correct part number is for the board. (The Lenovo service parts manual does not contain a reference for the 2374-E88).
Thanks in advance for any assistance you can provide.

Welcome to the forum!
Do any lights come on when you try to power on, is the fan spinning, any signs of life at all?
Good luck and let us know.
Cheers,
George

Syncing iphone and now phone is stuck and wont power off or do anything

syncing iphone and now phone is stuck and wont power off or do anything

Reboot the phone: hold down the power button and the home button at the same time until you see the Apple logo. Ignore the "slide to shut down". When the screen has been completely black for a few minutes, press the power button again.

If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.

Iphone 4 wont power on or charge

Plug it into a power source for at least 30 minutes, then reset it, while still plugged in:
Press the Sleep/Wake button & Home button at the same time, keep pressing until you(hopefully) see the Apple logo, then release.

Iphone 4s wont power on, im just getting a blank screen with battery charging on front screen

iphone 4s wont power on, im just getting a blank screen with battery charging on front screen>>>>becouse it is after damage water

At Apple Store, if you have AppleCare +, replacement iPhone 4S costs $50, if no +, then it will cost $199. Either your battery is faulty, the power management is faulty, or the charging port is faulty, or all three. Start with battery replacement. If still problem, then try charging port with flex cable replacement. If still problem, then it is very complex fix or no fix at all possible.

My computer wont power up. I have unplugged it for 30 min and replugged but it will still not power up. Can I try something else? cant get an appt until Tuesday.

My computer wont power up. I have unplugged it for 30 min. and replugged and it still will not power up. I cant get an service appt until Tuesday. Is there something else I can do?

Until Tuesday, the only thing you might try, if you already have and didn't state that you did, if this is the same outlet that you have used, and suddenly you lost power, try plugging your computer into another outlet and see if that works. If it works, either try another appliance in the outlet you are having trouble with, or check to see if a breaker has tripped.
If that doesn't work, well...you will just have tro wait until Tuesday.
Wish you the best of luck

ITunes crashed now Mac mini wont power back on

iTunes crashed now Mac mini wont power back on

You have not provided any information on which to base troubleshooting. Minimal information would include the Model Mac mini you have for example Mid 2010 Mac mini, exactly what happened when iTunes crashed, and what -- if anything -- happens when you try to restart. It is unlikely iTunes has anything to do with the failure to reboot but instead iTunes crashed because of what even caused your Man mini to fail.
Just as a starting point, be sure and check all your connections, power, monitor, keyboard, mouse, everything. You would not be the first to have a plug come adrift unexpectedly.

Iphone wont power on unless on charge and itunes cannot restore iphone,, what can i do?

I recently bought an iphone off Ebay, the seller said it was broken and described the problems too me, the phone in my view is fixable. The main problem i have is that the phone wont power on unless it is plugged in on charge. This is where it leads onto my next problem. there are a lot of ways people are describing to restore the phone if it doesnt work. (Hold down power and home, let go of power then it goes into a certain mode which it will let it restore then connect to itunes.) My problem is that to do this i have to be connected to itunes to get it to this stage.
the battery isnt the problem I have been told as the previous owner said they had replaced the battery already to see if that was the problem but it clealy wasnt.
If anyone can help me to restore this phone or tell me if I need to just take it to a repare shop. If there is a simple way of doing it myself and saving about £100 I would love to hear it!!!

How exactly were you able to do that? Since the only signed software, for your phone, is iOS 7.0.3, that's the only version of iOS you could install on your phone.

Tv wont power in takes several attempts

Hi I got a toshiba 32" tv from carephone warehouse with my mobile contract.
Literally for a week it was fine but since then when we power off (standby or via plug) it takes sever attemps to get it on-somes 30 mins plus. The red light will flash to green abd itstill wont power on. When we do eventually get it on it goes off as soon as I touch any button on the cable remote and we have to start again. Sometimes itll come on but with no sound and sometimes itll come on but keep going off and restarting. Ive had the tv 3 months. I contacted toshiba and tgete were useless basically was told factory reset which did nothing or call out a tech. Why should I pay a tech to fix a 3 month old tv. Ive Google'd and kniw others have had similar issues. Any advise?
Thanks

It does sound like it needs repairs. It should still be under warranty.

How do you transfer data from a good G5 hardrive that wont power up?

I have an old G5 that wont power up but the hardrive is still good, I want to pull the HD and transfer the data to my new Mac Book Pro, any suggestions? thanks so much

Reb,
You can do your file transfers with the swiss army knife that aqua suggested. That was my first thought.
http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/?APC=XLR8YourMac09
However, if you purchase an external firewire drive, it will give you far more options. You can install a clean system on it using your Mac Book Pro and try to revive your G5. The G5 will boot from an external firewire drive but not the USB adapter/swiss knife.
You can also open the external case, swap out drives and use it as a firewire version of the swiss army knife to transfer files from the G5.
If you get the G5 is going, you could look at Disk Utilities and see if something on the G5 drive is the reason the computer is not starting.
Just some options to consider.

I have an iPod touch 4g that wont power on

Hi. I just bought a iPod touch 4g second hand. It worked perfectly when i looked at it & when i got it. Ive had it for almost a month & out of the blue it wont power on or show that it is charging. How do i fix this? Is this something that can be fixed? Could it need a new battery or charging port? Please help.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have an install disc stuck in a g5 that wont power up is there anyway to get it out

Hello,
If all else fails,like holding mouse buttn down on bootup...
Other than that, you can slide the door of the optical downwards with your fingers, then use a straightened out paper clip to push into that tiny hole to eject the tray.
