How to baypass bios password on sumsung np300e5x


You can't bypass BIOS password. All you can do is to RESET BIOS, by removing CMOS battery and waiting some time till it discharges completely.
After you reset BIOS, you shuld enter BIOS at startup and input your setup values, so before doing this, you should check your BIOS setup. See some video tutorials but be careful. Dismounting a Laptop is not a joke. You may end with some parts in a shoebox rushing to your repair service...

Resetting cmos


The best way to RESET the BIOS back to the factory defaults if you do not know the Reset jumper or there isn't one is to remove the CMOS/BIOS battery and wait for approx. 20 mins for the charge in the BIOS to discharge.
If you cannot wait that long then short out the battery terminals on the motherboard with a paper clip.
Replace the BIOS battery, go into the BIOS setting and set the date and time etc.

Toshiba satelite bios password recovery


On laptops there isn't an easy way to recover passwords in the BIOS. Sometimes you can reset the password. Other times, you'll have to contact the manufacturer to get it reset.

Some laptops will allow you to reset the BIOS password by pulling the CMOS battery. The CMOS battery is typically located under one of the bottom panels for access to the memory or wireless cards. Some models have the CMOS battery connected by a small wire with a clip connector, others have the CMOS battery placed directly on the motherboard with a metal retainer clip.

Here is a link to a removable CMOS battery with wires: http://www.laptopparts101.com/wp-content/uploads/2008/12/removable-cmos-battery-560x420.jpg

Here is a link to a CMOS battery that is directly on the motherboard: http://www.laptopparts101.com/wp-content/uploads/2008/12/coin-cmos-battery-560x420.jpg

On a laptop, if you unplug the power cord, remove the laptop main battery and then remove the CMOS battery - and then wait at least 5 minutes, some models will blank out the BIOS password. Not every BIOS password can be erased by removing the CMOS battery - but if you are comfortable working on the laptop parts it is worth a try.

If removing the CMOS battery doesn't fix the BIOS password, the only option left is to contact the manufacturer for a reset. (If you took your laptop to a certified technician - they would just contact the manufacturer for the reset, and then bill the time to you!)

The number to contact Toshiba is 1-800-457-7777.

I have a Wipro Laptop. His BIOS is Phoenix. It has a CMOS password. How shall I clear the password.\?


Hi Nayanranjani.

As you trying to reset the BIOS password, let me provide the required steps.

You may reset the BIOS password by just removing and inserting the CMOS Battery.

The CMOS Battery will have the Computer date, time and also the BIOS password saved in it.

Hence, removing and re-inserting the CMOS password will reset the BIOS password.

Once the BIOS password is removed, you may assign a new BIOS password.

Hope this helps.

Please feel free to ask further questions.

Acer extensa 4220 bios password


There's no way that we can determine the BIOS password of your laptop. But if you can disassemble your laptop and locate the CMOS battery you can remove the CMOS battery to reset the BIOS together with the password. After resetting the CMOS battery you will no longer be asked to enter a password for the BIOS when you turn on your computer. However, there are instances that even though you reset the CMOS it's still asking for the password, for this concern, the computer manufacturer should deal with this concern.

Need to reset bios password for acer 4620 laptop. tryed removing battery on mb . no good . ? passmord bios


Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.
