Re: C46_ lenovo_la-3691p bios requreid

if i flash bios with bios file provided by hbissou then laptop continue on but no display,

[Ramee]

Re: C46_ lenovo_la-3691p bios requreid

Even on external monitor no display? Check the panel, cable and voltages coming out from the cable.

[sanehdeep2012]

Re: C46_ lenovo_la-3691p bios requreid

no display in enternal or external ,

this is faulty releated to bios or south bridge might be,
