Problema pantalla L412

Hola mi laptop se quedo con la pantalla negra, entiendo que puede ser porque se le quemo algun componente (Foco de la pantalla, panel de la pantalla e inverter para la pantalla). Ahorita queria saber si alguien sabe acerca de cambiar pantallas de este tipo que me pueda guiar.
Ocupo saber si este modelo cuenta con inverter remplazable y donde se ubica en la computadora
Imagenes adicionales de mi pantalla y especificaciones

Tu L412 tiene pantalla LED de manera que no hay inverter. Si mal no recuerdo el LED subcard esta integrado en la motherboard.
Si buteas la laptop y alumbras la pantalla con una linterna, puedes ver algo?

Then use the last of the How to Troubleshoot iSight suggestions:
"... contact Apple or an Apple-Authorized Service Provider for service."

Problema al conectar el mac a tv philips, pantalla en rosa

Hola, tengo un macbook air de diciembre de 2012, y mi tele es una philips, al conectar con el hdmi y un adaptador para el thunderbolt; se ve perfectamente, pero al cabo de un rato la pantalla se pone de un color rosa y verde, como puedo solucionarlo?

Puede ser que se deba a un problema con la configuracion de la television, si funciona con otra television entonces debe de ser algun problema de configuracion, haz probado conectar otra maquina a esa tv?
Gracias y Saludos,

I have problem with Access Connections on L412 after that utilyty upgrade

I have problem with Access Connections on L412 after that utilyty upgrade in early August. Windows 7 Ultimate/x64.
It stops connecting to WPA2 Enterprise (AES-CCMP), Microsoft PEAP, no server cert, with any credentials I try to use. The same account(s) works with native Intel manager on other notebooks and on mobile devices. I lost the wireless connectivity to enterprise WiFi network.
And, after deinstallation of Access Connections, the inability to connect keeped intact with native Win7 WiFi management.
I think, something was broken in Access Connections 5.83 Build 83C753WW and some registry settings/ dll modules were altered but not returned to normal after deinstall.

Access Connections is definitely broken for WPA encryption. Both versions 5.02 and 5.84 fail for me. If I use the Windows XP wireless configuration instead of Access Connections, everything works.
Does anyone know how to report this to Lenovo? I chased links around the web site but couldn't find a place.

PROBLEMA AL ENCEDER EL IPHONE SE ME QUEDA LA PANTALLA CON LA MANZANA Y NO ME DEJAR HACER NADA

Did you try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again after the screen went black?
Connecting in recovery mode can also help:

L412 bios/overheat problem

This is something for other users/Lenovo to be aware of. Last night, I realized that my volume buttons for my L412 stopped working for Ubuntu. I didn't think much of it, assuming it was something with the OS. I usually put it to sleep using the function key at night, but that also wasn't working, so I just left it on overnight because I had stuff open.
I came to it this morning and it was running very hot, hotter than I've ever seen it. I rebooted into my native Windows 7 and I was still unable to use the Function keys or the volume control buttons. I shut it down and turned it back on again and the fan never came on at powerup like it usually does, and when I rebooted Windows, CPU was at 79*C and HDD at 51*C!! Usually HDD Is in the low 40s and CPU in the high 40s.
I shut it down, unplugged it, took the battery out, held the power button for a few seconds, powered it up again, and now all is well; the fan started racing right away and it's been fine since.
That was BIOS 1.37. I've updated to BIOS 1.38, which hopefully fixes this problem, however, let it be a warning to the Lenovo engineers to fix it in the next update if it doesn't, and to everyone else so you don't fry your computers if you notice any of these symptoms!

It's happened again! CPU at 81*, HDD 50*.
Some additional information: This time, I had used the computer on battery during class, taken it home, plugged it in like I always do, and started using it. Again, no Fn or sound/microphone control functionality, or cooling.

hello! my problem is that my ipod touch is locked, and when I try to slide my finger the screen does not respond, and eh already tried but does not work! that pued do?
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 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.

See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Featurs appin the Window Control Panel. Then reinstall all the Apple software components
- New cable and different USB port
- Run this and see if the results help with determine the cause
iTunes for Windows: Device Sync Tests
- Try on another computer to help determine if computer or iPod problem

L412 BLACK SCREEN PROBLEM

There was a power otuage and my laptop went black after the power outage. The battery was not inside the laptop when the power outage occured. When the power outage ended, I powered back on my laptop but it won't been nor will it boot onto the Lenovo Boot Screen where it will say Thinkvantage.
Furthermore, it won't boot onto windows. It just sits there when I power it on with only the wireless adapter on. . What's the problem?
I already removed the power plug, unplugged and replugged the battery, held the power button for 30 seconds, pressed it 10 times, and removed HD and memory. Still doesn't work. What's the problem?

As I understand the issue there is no display when you power on the laptop.
The issue can be with the system board , you should contact the service center for the repair.
Best Regards,
Tanuj
