Your RTC battery or CMOS battery is either dead or too low to keep the correct settings, windows will not operate correctly without the proper date and time kept. This battery has to be replaced for your system to operate. Below is the service manual that will advise you of the proper procedure to replace the battery. Once the battery is replaced, reboot the laptop, go to the BIOS screen and reset the date and time, then reboot as normal. In the case of your particular laptop, the laptop has to be disassembled down to the lower case and motherboard. The included service manual has the procedure for this.

Testimonial: "thank you for your help. I will replace the batter but Im not sure what you mean by this sentence "In the case of your particular laptop, the laptop has to be disassembled down to the lower case and motherboard. The included service manual has the procedure for this. "
No manufacturers password that I have ever heard of but you can remove your keyboard and disconnect the mother board (BIOS) battery. Leave it disconnected for a few minutes. When reconnected the password should be gone. A few laptops actually have a jumper to do this.
