evo da ti malo pomognem, probaj prvo s ovim izvafi bio bateriju i drži je vani odspojenu jedno 10 minuta ne treba duže, spoji je natrag, sastavi laptop, da zaboravil reči bateriju izvadi van i neka bude vani, probaj onda na punjač spojiti laptop bez baterije i upali ga, ovo je sa service manuala od laptopa ali ne pali na svakom.
Evo ti i malo teži način ali bi to moralo onda funkcionirati to sam dobil na nekom stranom forumu jednom:
"only 2 ways to reset (clear) bios. 1 - is to unplug cmos battery located under keyboard and wait at least 3 days (10 days is recommended) before putting battery back in or AC power.If password is still there then repeat and wait longer. or option
2 - remove motherboard, locate bios chip on the back (upper left hand corner) , just below the bios chip there is a capacitor (NEK jE8) use a volt meter to discharge capacitor. Use the lowest setting like 2.5v, connect ground test lead to ground and hold positive lead to the + side of capacitor. Continue to hold untill you have zero voltage, once you have a zero reading, locate the fuse (M15) , on same side of motherboard, just under the docking station, use same process until discharged, Flip motherboard over and locate capacitor just to the left of the cpu, Use same process until zero, flip back over and return to the capacitor next to the bios chip and test, if zero your good to go, if you still have voltage repeat process until zero reading on both capacitor and fuse. Remember all this is to be done with No power from AC, Battery, and CMOS. Discharge process should take about 20 minutes. Tested and proven 100% and much faster than 3 to 10 days. Remember this will void your warranty. Good Luck"
