I have a problem with my Dell N5110. this worked with External monitor fine. But Led working backlight only not any display on the screen. i checked LCD_VDD and is shown Power 0V. I found U4901 is faulty on this MB. Thereafter i tested with a jumber to pin 3 with pin 4. Display worked fine. i shut down the notebook. But unfortunately this jumber wire has Shorted with PR4002 ( DCBat out 18V ) after shut down the notebook. Now i changed blown fuse on the led screen and this notebook is giving 8 beep sounds ( Says No display attached. I try with the external also but same ). any one having idea ?

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, I have a Dell XPS 9500 which works when it want. Specs : I7 10750H, GTX 1650Ti 4GB, 15.6" 1920x1200.
It can works fine for hours until the screen goes black or the image is fully frozen (laptop unresponsive) or the display is glitched.
Then another issue is sometime the laptop doesn't wanna boot or post at all, after a "clear cmos" (disconnecting main battery and pressing power button for some time) when I'm pressing the power button the keyboard lit up but sometime the laptop display the Dell logo, sometime the screen can just lit black, sometime it launch... -
