Error code 0176 concerned with System Security. The system has been tampered with.
Try to enter the bios setup. Save the bios setting and exit. Lets see if it resolves your problem

SOURCE: bios lock, ERROR CODE 0271
Error code 0271 - Date and time error. Neither the date nor the time is set in the computer.
Run BIOS Setup Utility to reset the time and date
It sounds as though your computer has the wrong time in the CMOS. The CMOS (Complementary Metal-Oxide Semiconductors) is the chip that holds the basic startup information for the BIOS, system and its peripherals while the system is turned on and off.
If you can get into the BIOS check the date and time settings and make sure they are correct.
It may also be a case of the CMOS battery going out. When this happens your computer will tend to not keep the correct time. They are cheap and relatively easy to replace. Before buying a new batter your can try to take it out and let it sit for about 10 minutes or so to reset the CMOS and then go put the battery back in and go into the BIOS and reset the clock.
Hopefully taking the batter out or replacing it will get past your lock icon asking for the password. Just search for CMOS or BIOS default password for your brand of laptop.

Both errors are related to the backup battery which is located under
the main battery. It is probably dead. You can get one on
eBay for $3.29 w/free shipping or pay a shop $20 to put one
in. If you do it yourself be very gentle plugging it into the
tricky little slot - it is possible to break the connector loose from
the motherboard but it is an easy repair if you have patience and
dexterity. As for the password, try just hitting enter. It
is the supervisor password to change the BIOS settings and was probably
Hope this helps.

Change the bios battery.Remove the notebook battery and then you should see the bios battery.Maybe you should have to disassembly the complete pc because it is a little dificult without disassembly.
