Dell N5110 3 Beeps

[John_F_L]

Hello, I have a Dell N5110 Intel version with Nvidia graphics and when it starts I get 3 beeps. Board model 48.4IE07.011. I started by changing RAM and CPU, nothing changed.
Then I tried to reprogram bios with a downloaded dump, again the same. Next try, I changed the IO chip, the same.
Last thing I did I open schematic and boardview and check all the voltages from the power sequence page, and they are all present.
Anything else I can try before I give up on the machine?

Re: Dell N5110 3 Beeps

is there any display?
does the fan spins?
is the voltage for the GPU present?

Re: Dell N5110 3 Beeps

there is no display...
the fan spins...
all the voltages are present...
I followed all the power rails from the schematic and check every one.... all correct.

Try converting the mb to UMA so that you can rule out nvidea graphics issue.

the customer doesn't want to pay so I can do all that job converting it to uma. So I'll give it back unfixed and all done.

It would have taken 5 mins to convert it to uma. Anyway, its your customer and your choice.

Re: Dell N5110 3 Beeps

it's not five minutes... I searched through internet and to convert the N5110 to UMA there are a lot of components to be removed (together with the BGA)

John bro, you are mistaken or you have given wrong model. as long as it is DEll Inspiron N5110 -it will take less then 5 mins with no bga work involved. However, if it is N5010-then there is lot of things to modify. If you still have the laptop-i can give you the knowhow for N5110 Conversion from dis to uma.

No need to remove bga(thats optional if you want to reduce power consumption). Just need to do the following:

01. Remove PU9303(vga power)
02. Remove GFX Coil.
03. Shift R2011-2013(located near HM chipset)

100% Working solution.

I do this solution on my laptop but not working. There is backlight on but no display on screen. Need to change bios or something ?
