Lenovo U310 LCD Screen Backlight Won't Turn On.

I purchased a new U310 near the end of August this year, using it primarily to bring with me to school. However, I've been having a problem with the LCD screen backlight. Typically, when the computer starts up, the backlight will be working fine. However, once the computer goes into powersave mode and shuts the display off, often the backlight to the display will not turn on again regardless of if I press keys or the touchpad. These are some things I've noticed:
The display IS still on. I can still very faintly make out the desktop and use the system, but the backlight is off completely
This issue does not happen all of the time, but is still quite frequent
Sometimes putting the computer to sleep and then waking it solves the problem, but not all of the time
Sometimes the backlight remains off even after a forced power off (holding down the power button), but typically a restart solves the problem and enables the backlight again
Adjusting screen brightness has no effect
This happens regardless of the battery level and whether or not the system is plugged in
Although this issue has seemed more prevalent recently, it even happened on the day I bought the laptop, but I just wasn't yet aware it was a reoccurring issue
I've been able to recreate this issue, in fact I was just able to make it happen twice in a row. First time the display went off and didn't turn back on, I restarted. This even repeated the next time the display went into powersave mode, so I restarted again. The third time the display went into powersave mode, I was able to turn it on again simply by touching the touchpad (as it should be).
I think that about sums up what I know. I apologize for making such a long post, but I'm thinking I can't be the only one with this issue. I'm new to the community and couldn't find a similar post anywhere on the forums. Since I infrequently use this system, and the issue has been there since I got it, I'm assuming it must be a driver problem. If anyone has any insight or is experiencing similar problems, I'd be glad to hear! I thought I'd post before contacting Lenovo directly. Thanks!

I suggest you please uninstall the energy management software, reebot and install it again. You will find the setup of energy management in drivers folder in the drive named lenovo ( maybe E or D). Please give it a shot and post results.

MacBook Pro (Late 2008) Screen Backlight won't turn on

Yesterday, I pulled out my MBP and started it up. The screen was "black," and at first I thought that it was totally dead, but a closer inspection revealed that the display was working, but the backlight wasn't turning on. I restarted, and the backlight came up to half brightness (even though the brightness adjustment buttons would say it was at full). A second restart would bring it up to full brightness, and it would run fine from there (unless it had to shut down again). This double-restart fix worked for about a day.
Finally, it gave out. (The last thing I did before it totally died was turn down the brightness; when I got to about 4 bars, the backlight totally turned off and stayed that way.)
I've tried restarting about 50 times, resetting PRAM, and resetting the SMC. So far, none of it has made a bit of difference. The computer is running fine (I can see the screen if I point a flashlight at it), but the backlight remains definitively off.
This computer has run pretty smoothly since I got it; I haven't had any problems with Lion since it installed, and the only thing that I did between the last time I shut it down and discovering this problem was go through airport security (which I've done many times before with this computer in tow).
If anyone has had a similar problem, or a solution, I would love to hear it.

sgmcb,
It looks like you've covered everything you need to do. It could be any number of things, but logic board seems the most likely. Not a cheap repair.
Don't take my word for this. Bring your MBP to your local Apple Store/Genius Bar and have them take a look at it. They won't repair anything, but they might be eliminate a few possibilities.
I just hope you post the results of your visit, in case others have a similar problem in the future!

My phone is doing the same thing. My computer acknowledges that I have connected my iPhone 4, however, iTunes will no longer connect or sync to my iPhone 4. I have uninstalled iTunes, Bonjour and all Apple products from my pc. I have re-installed them back on. I have reset my phone. I have emptied my temp folder. I have done everything. If my iPhone cannot update and sync with iTunes then I may as well get another phone from somewhere else. I am disappointed that I cannot resolve this issue.
Rebeccaspe31, were you able to resolve your issue? If so how?

Hard Reset: HOld the home button and the sleep/wake button of your iPhone for about 10 to 15 seconds at the same time. Holding down both buttons at the same time till you see the apple appear

My phone keeps displaying a white screen with the apple, then occasionally flicks to a blue screen, but won't turn on! HELP!!

Restore your software using iTunes.
Turn your device off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your device and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a device in recovery mode. Now you can restore to factory settings.
You should be able to restore your backup file after this procedure. If the problem comes back, you either have corruption in your backup file, or a serious hardware problem that should be looked at by a tech at the Genius Bar (make an appointment first).

Lenovo T410s LCD screen problem

I've got a problem with my LCD screen on Lenovo T410s. Everyting worked good so far. Today I wanted to check another LCD for that model which I've got. So I dicsonected the original LCD, and conected the second one to check. After I saw that the second one worked good, I disconected it. Then I conected again the original one and started the laptop. Unfortunately when it started, the screen didn't shine good - it's very dark. I disconected the one and tried back the second LCD, but again the second one shined very bad. Can anybody tell me what could happened? It looks like the inverter is demaged, but I don't even know where is the one inside that model. Please give me some advices
Solved!
Go to Solution.

These fuses are extremely tiny and not meant to be user-replaceable.
You'd have to pull the board out and start measuring them one by one until you find an "open" one.
No clue where exactly these are on a T410 board.
Good luck.

George

IPod Nano 4th gen - screen flickers, won't turn on, isn't recognised by computer or iTunes.

My 4th gen iPod Nano has been playing up.
When I connect it to my computer or a dock, the screen flickers with the Apple logo. Once unplugged, it won't turn back on and the screen goes completely black. I tried to reset it numerous times (both connected and unplugged) but that didn't help at all.
I tried to see if I could fix it by restoring it and putting it in disk mode, but the iPod isn't recognise by any of the computers in my house and doesn't appear in either iTunes or 'My Computer' so that really doesn't help. I'm positive it's not an issue with my computer or USB cable because the other iPods in my house connect just fine.
Any idea on how to fix this?

If you have synced your iPod touch to a computer, it should be relatively easy to fix. Plug the iPod into the computer to which it is synced. Once plugged in, hold the home (square button on front) and the power button on the top for approximately 10-15 seconds. After the apple disappears from your screen a couple times, a new screen will popup indicating to start iTunes on your computer. Once you start iTunes, you will be given the option to begin the restore mode and then choose to restore your particular iPod. Once again, you have to had synced your iPod to a computer to utilize this option. Not sure how I figured it out, but I finally did! Good luck and let me know if it does/doesn't work for you.

My Screen Saver won't turn off on my I-Mac. Is there a way to fix this?

I have an I-Mac that every once in a while won't turn off it's screen saver when I move the mouse. I can see the mouse move and switch to the screen with the caculator, but I am unable to get the screen saver to stop and view the screen proper.
It has been updated with mavericks, but was doing this before the update. It's set to update on a weekly basis, so It should be good in that department.
so far, any suggestiosn I have been able to find haven't stopped this from happening. i'm looking for a way to exit out of the screen saver.

Have you tried going to System Preferences/Desktop & Screensaver/Screensaver, and choose "Start after Never"? That turns off the screensaver. Then, under System Preferences/Desktop & Screensaver/Desktop, choose the image you want. You can vary the sleep by playing around with System Preferences/Energy Saver, and playing around with your preferences.

Keyboard backlight won't turn on after spill.

Yeah so, me being a complete idiot, I was holding an open bottle of Snapple right next to me while laying down on my bed browsing stuff when I inevitably spill it everywhere. All over my sheets, clothes, and of course my keyboard. I immediately turned it upside down and drained the liquid, also rubbed the entire keyboard with a wet rag and some rubbing alcohol. All the liquid/stickiness is gone and the keys work perfectly fine, albeit the smell is still faintly there. But the real problem is now my backlight won't work. I noticed it flicker while cleaning it but thought it was nothing.
Any general way on how to fix this? And no, I'm not spending a thousand bucks and wait a month for some dudes to take the whole thing apart and wipe out my harddrive again for no reason.

OK, Wow.
Whenever a liquid spill occurs the first thing that has to happen is the laptop should be shut down immediately. All power must be removed as soon as possible. It is especially important that the battery be disconnected and removed.
All affected parts must be removed from the laptop. No attempt should be made to start/restart the computer since this could potentially damage the logic board beyond all repair.
Then all affected parts would be washed in deionized water and blown dry with compressed air. (In a water spill the deionized water is probably not as critical. Depends on the mineral content of the water.).
This is especially true of the large chips on the logic board. Liquid can wick under them and cause havoc for weeks if not months after the incident.
The logic board should be placed in a drying/dehumidifing oven for at least two days. Longer depending on the spill.
The keyboard is a separate matter as described below.
This is how these keyboards work:
This is the contactor array of a MacBook Pro 2011 13" . You're looking at it from back to front. Those round dots are where the silicone rubber "cones" cause the front array to make contact with the back array, telling the computer which key has been pushed. The width of these (I think deposited silver ) traces is about 0.5 mm.
Now you're only looking at the just the front array. You can see that the contact pads are connected in series. A break anywhere in the trace connecting them would cause the "downstream" keys to stop working.
So here you see a site where ionic corrosion occurred. I know that this particular MBP was exposed to water. So I bought it very cheaply. I was able to clean and completely dry out the logic board and the MBP worked fine for a while but quickly the Q - W - E - R -T - Y - P keys got wonky then completely stopped working. I bought a replacement keyboard for cheap but then found out that it's held to the front frame with around 80 tiny screws. So I was using it with a BlueTooth keyboard. Recently I bit the bullet and for $69 bought an entire top case for my machine. Putting it in meant that the everything had to come out of and off the top case.
So you can see from the amount of corrosion, it doesn't take much to cause a failure. In this case a drop of liquid less than 0.5 mm would, over time with ionic action, cause a failure. There was a post about someone who had their MBP in a leather case and when they opened it up there was a lot of moisture on it. It was winter where he lived and we figured it was condensation. So even without spills this could happen.
So since your problem was with a sugary drink the sugar will be hydroscopic, that is it will attract water out of the air and keep the contact area moist. This will lead to future failures be it on the logic board on on the keyboard membranes.
The backlight being part of that array you've been looking at. (Finally got to it.)

White Screen and Won't Turn On

I just bought a used Ipod Touch 3rd Gen 32GB, but the Ipod won't turn on and it's not working.
If it ever turns on, it's always a white screen.
What can I do to solve this problem???

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

When updating to the new iOS my ipod died and now I have nothing but a white screen that won't turn off and itunes now doesn't recognize it

When I was updating my ipod touch to the new iOS last night it died and now I have nothing but a white screen. iTunes no longer recongnizes the device and it won't turn off when I hold the power button or when I hold the power and home screen button.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
