Re: dell lcd brightness problem
Sometimes if your connection cable for the LCD display is not plugged in tightly enough it can cause a dim display. Recheck your connection. Also, try adjusting the display contrast to the brightest setting. Disable any ambient sensor if equipped.Comment

Re: dell lcd brightness problem
actually dell laptops only support the lcds which comes with inverter and specially made for dell .i think by changing the bios or fermwire chip on lcd can solve this issue.any one can point out the location of that chipComment

Re: dell lcd brightness problem
what about measurements ? vin, brigthness and on/off =? i think you have vin = 19v and on/off ? 3.3 but dont have brightness signal, chek with schematics and if you dont have the brightness then solder a wire from nearest 3.3v.Comment

Re: dell lcd brightness problem
disconnect the brightness pin first from the connector before solder a wire from nearest 3.3v on it . do this to avoid return current on the board .Comment

Re: dell lcd brightness problem
agree to spidey . LCD screen with LVDS connector is a standard .
only Vin , on/off and brightness signals are necessary to light up the screenComment

Hello, I have a Dell 15R-5521, with the problem that the Ctrl, Alt, Shitf and Num Lock keys do not work, I tested the keyboard with a keyboard tester and it is functional, I also got another new keyboard and the computer has the same problem with the same keys. Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.
As additional information,... -
Hello everyone,
so, I have this laptop Dell Inspiron N5110 with a heating problem on both CPU (I7-2680qm) and GPU (GT 525m), I tried many solutions, like changing thermal paste every month, using thermal pads on CPU and GPU, even using thermal pads on CPU nearby coils; but nothing worked, just minutes after booting the laptop shuts itself down so I thought it might be a short problem, so I decided to check what's going on, so I went online and some tutorial (general one) said to check inductors in order to find the shorted circuit, after checking (CPU removed), I found the culprit to be... -
Hi everybody. I have a Getac S410 G1 with a screen brightness witch cannot be adjusted. It is at full brightness when the charger is plugged in (19V on the LCD connector) and at minimum under battery (12V on the LCD connector). Does anyone know where the problem is coming from ? Thank you.

Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen....
