Question about Samsung NP300E4C-A02US Laptop

1 Answer

Bios reset My aunt somehow put a bios password on the laptop. I've tried everything from using the RTC jumpers to taking out the CMOS battery for 2 days and replacing it, nothing so far is working. I cannot boot into windows, as soon as the screen flickers on the password is needed. She has no idea what the password could be since she was just pressing keys, any ideas?

By resetting the CMOS battery all you need to do is to teardown your laptop and have to remove and reinstall the CMOS battery. And for the replacement of the CMOS battery of your Samsung laptop just call SAmsung technical support so that they can give you the exact model of the CMOS battery and where you can have the battery. Thank you.

SOURCE: hi, i have a samsung v20 laptop.2 questions...

I have a Samsung V20 for many years and I know it doesn't support a wireless connection built in. But if you connect a USB like myself you can have access to the internet wirelessly. The flikering on the screen are you sure you haven't got a screen saver switched on, you may have it set to a clear black screen and like you say have to tap the keyboard and it comes back to life. It may also have hibernation switched on which will automatically turn off the screen have so many minutes you can change all these setting by right clicking on the desktop and selecting properties and under the screen saver tab there will be a power btton you should see hibernation and other tabs across the top these can be altered to whatever you want.

Hope this of use.

1) Remove the AC adapter (Charger), and main Battery.

2) The CMOS Battery is now referred to also, as the RTC Battery.
Real Time Clock

3) Turn the laptop over, bottom side up.
The large rectangular cover in the middle, is the Memory Door.
Loosen the screws, lift on the Memory Door; on the screw side.

The RTC Battery is a coin-cell battery, in a plastic holder ('Bag'), with two wires coming out, that end in a small male plug connector.

Unplug the male connector from the motherboard, remove the RTC Battery.

Past this point cannot tell you exact location of those jumper pads.
Usually under a piece of Mylar plastic.
Often under the Ram Memory modules, or under the Wireless Module. ('Card')

The RTC Battery helps retain that password.
However there is also a capacitor, or capacitors; that hold a trickle charge - INDEFINITELY, after ALL power is removed.

Briefly touching the aforementioned jumper pads, relieves this stored trickle charge.

applebook - 29th June 2008,

"There is no way to reset the Bios on the new Latitudes. Removing the power and PRAM battery does nothing. Everything in the Bios is contained in the EPROM flash chip and keyboard ROM chip. The E series uses a chip that cannot be reset by jumpers either."

Next plan of attack is to take;
1) Drivers license, or some other valid form of identification
2) Proof of purchase
3) Credit Card
4) Laptop

,down to nearest Dell authorized repair shop, and have the resident tech obtain the Master Password from Dell.

The Master Password will be used to either;
A) Create a new password
B) Eliminate the password

Tech keeps the Master Password.

I need to rest password in bios


Hi,
Removing the RTC battery and leaving it uninstalled for 5 or more minutes causes all passwords and CMOS settings to be cleared. BIOS password can be removed by temporarily disconnecting/ removing the RTC/ CMOS (Coin-cell) battery from the motherboard.
Disconnect the coin-cell battery from the system board and it will reset the BIOS to its default setting and the password would be gone.
Please Refer to Page 29, 106 & 79 of the REPAIR MANUAL IBM T40 for Battery removal, keyboard removal and RTC battery removal instructions.
The Backup Battery (RTC, CMOS) is located under the keyboard. So you have to remove the keyboard to access the battery. The above Manual from IBM shows the exact method/ instructions and pictures for laptop dis-assembly for the purpose.
If you are comfortable with working inside such electronics, you can't do it yourself, or else you may seek help from local laptop service professional.


Hope it helps! Good Luck! Thanks for using Fixya!

Dell vostro a860 bios password


The best method to reset a BIOS password depends on what BIOS the computer has. Common BIOS's include AMI, Award, IBM and Phoenix. Numerous other BIOS's do exist, but these are the most common.

Some BIOS's allow you to require a password be entered before the system will boot. Some BIOS's allow you to require a password to be entered before the BIOS setup may be accessed.

The general categories of solutions to reset a BIOS password are:

* Using a Backdoor BIOS Password
* Resetting the BIOS Password using Software
* Resetting the BIOS Password using Hardware
* Vendor Specific Solutions for resetting the BIOS Password

Using a Backdoor BIOS Password

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.
AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords

One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
Backdoor BIOS Passwords from Other Manufacturers

Reported BIOS backdoor passwords for other manufacturers include:

Manufacturer BIOS Password
VOBIS & IBM merlin
Dell Dell
Biostar Biostar
Compaq Compaq
Enox xo11nE
Epox central
Freetech Posterie
IWill iwill
Jetway spooml
Packard Bell bell9
QDI QDI
Siemens SKY_FOX
SOYO SY_MB
TMC BIGO
Toshiba Toshiba

Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.
Resetting the BIOS Password using Software

Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.

You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

CmosPwd will recover the BIOS password for the following BIOS versions:

* ACER/IBM BIOS
* AMI BIOS
* AMI WinBIOS 2.5
* Award 4.5x/4.6x/6.0
* Compaq (1992)
* Compaq (New version)
* IBM (PS/2, Activa, Thinkpad)
* Packard Bell
* Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
* Phoenix 4 release 6 (User)
* Gateway Solo - Phoenix 4.0 release 6
* Toshiba
* Zenith AMI

Resetting the BIOS Password using Hardware

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.

Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

RTC's which require external batteries include:

* Dallas Semiconductor DS12885S
* TI benchmarq bq3258S
* Motorola MC146818AP
* Hitachi HD146818AP
* Samsung KS82C6818A

Most RTC chips with integrated batteries can be reset to clear the BIOS password by shorting two pins together for a few seconds.

You will see more than one option for some chips due to testing by various people in the field. Remember to remove power from the system before shorting these pins.

RTC Chip Pins
Dallas DS1287A
TI benchmarq bp3287AMT 3 (N.C.) and 21 (NC/RCL)
Chips & Technologies P82C206 12 (GND) and 32 (5V)
-or-
74 (GND) and 75 (5V)
OPTi F82C206 3 and 26
Dallas Semiconductor DS12887A 3 (N.C.) and 21 (RCLR)

You should be able to discover how to reset the BIOS password stored in most RTC (Real Time Clock) chips by reading the manufacturers data sheet for that RTC. Some RTC's, like the Dallas DS1287 and TI benchmarq bq3287mt cannot be cleared. The solution to resetting the BIOS password on systems with those RTC's is to purchase a replacement RTC chip. How inconvenient!

How to break the bios password?


Hello,

All you need to do is just to power off your system, remove the battery and unscrew all the screws that will lead you to your board.

When you are at the board, remove the cmos battery of your laptop and put back your laptop battery to power on the laptop for a while, power on without the cmos battery, your laptop will be reset and will not ask of the bios password anymore.

After it has been reset, you can now put back the cmos battery and couple everything back.

Your laptop will work without asking you bios password anymore.

Take care

Unable to reset bios password - removing coin cell battery had no effect


Then you can try it out by removing the jumper.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password.
The location of this jumper varies depending upon the motherboard brand.You should read your motherboard
manual to check its location.If you don't have the manual then look for the jumpers near the CMOS battery.
Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS etc.When you find the jumper,look carefully.
There will be 3 pins and the jumper will be joining the center pin to either left or right pin.What you need to
do is remove the jumper and join the center pin to the opposite pin.e.g.if the jumper joins center pin to left pin
then remove it and join center pin to right pin.Now wait for a few seconds and then again remove the jumper and join
the center pin to left pin.Make sure to turn the PC off before opening the cabinet and resetting the jumper.
