Re: Lenovo G50-30 BIOS dump and fixes?

Thanks,
I've just was wandering what cause this behaviour.
One BIOS - balcklight,
Another - no backlight but screen polarization.

Re: Lenovo G50-30 no POST on powerup

Today I've changed KBC for new preprogrammed one.
Same story - so my old KBC was acting same as new one.

Re: Lenovo G50-30 BIOS dump and fixes?

I've also tried many other bios dumps, found on internet - and only 2 results, black LCD or with backlight.
Also I've tried to move DMI from original BIOS to one posted here - black screen,
and also to the BIOS that enables backlight - nothing has changed,
so my conclusion is that DMI doesn't store information for proper LCD run.

Re: Lenovo G50-30 BIOS dump and fixes?

Hello,
I'm struggling with Lenovo 50-30.
Can't get screen on LCD.
I've ordered new IT chip (preprogrammed) - and didn't help.

I've narrowed problem to BIOS somehow.
Original BIOS - LCD gets polarized and black, no camera light blink - display only on HDMI or VGA (but when LCD is disconnected).
Different BIOS - LCD comes with backlight, camera diode blinks, but again - nothing on LCD only backlight. Display on HDMI or VGA (when LCD is disconnected).
What part of BIOS speaks with LCD to...

Re: Lenovo G50-30 no POST on powerup

So I'm stuck on this:
1. Original bios from mobo with cleared ME region - Black lcd with polarisation, works HDMI (with plugged LCD), VGA - only when LCD disconnected,
2. 2nd bios - withe ME cleared - same situation but LCD has backlight.

So different bios different LCD behave.
Can it be KBC needs reprogramming somehow?

Re: CH341A Unable to Read BIOS Chip on DA0R53MB6E1 Motherboard

Hi there,
for all having issues:
1. Install drivers with PAR in the name - for programming,
2. Make sure chip has good connection - soldered into breakboard (I know what i say, checking continuity with a multimeter - everything was fine - but chip wasn't detected. Resoldering chip and breakboard pins helped)
3. 1.8V adapter not especially needeed - I've one and with poor soldering the chip, programmer didn't detected it - but it did connected straight to programmer without 1.8V adapter. After...

Re: Lenovo G50-30 no POST on powerup

Hello,
I've got an G50-30 NM-A311 rev 1.0 mobo with no display - only led and no display.
Found burning hot KBC chip. Bought a mobo which comes to a backlight, capslock working, cpu seams heating up - but no display.
Replaced KBC chip from bought mobo - and nothing - no backlight, capslock.
Replaced BIOS chip from bought mobo - starts up, shutes down, caplock working - but nothing on display but backlight.
Tried differend found bios'es , but backlight and capslock work only in this from a bought donor board.
