I don't think it helps but you said you removed the BIOS/CMOS battery and it didn't work. Try again and remove it for at least an hour, in some cases this has helped.
I've removed it for an entire night at one point (at least 8 hours). It reset the Bios date and time at best. All the basic things I believe I might have tried them all. I'm thinking this is one of the newer laptop setups where the CMOS battery only affects the bios time, the information may stored elsewhere
You are probably right. You could also try asking the manufacturer for help. Maybe they can recommend something at least, because it is really quite new and there is almost nothing on the internet to find about it. I can find only BIOS update download and in which computers it have been used.
Yeah, I've done this actually. I contacted them they said they could fix it, but it would require about a month due to shipping fixing and returning (no less than 15 days in their words)... So honestly I would want to keep that as my last resort. The laptop is still under warranty as well, but they claim bios password resetting isn't covered and they can't give me a price range until after I ship it in. A technician did tell me it's probably no less $150 US to reset the bios... If it was I could pay and get it fixed in a few days then sure. But this is a waiting game - I pay to ship it to the manufacturer, then they will tell me a price which I'll have to choose to accept (or I wasted my time), then more waiting for a fix and a return... So yeah, definitely my last option.
remove battery , unplug laptop, press power on put back battery plug laptop try again is this help? ____________________________ or u can use bios password reset tool
Sorry for the late reply, take it to a hardware shop and ask them to flash the bios (ROM) chip. You can do it yourself too if you happen to have EPROM programmer with SOIC8 clip
