Quên Password CMOS của laptop??

[TNTANH]

Máy Compaq V5000, password lúc boot thì nhớ, nhưng password cmos thì quên mất rồi :(( :(( , để xài thì cũng bình thường, vì mình đâu có cần chỉnh gì trong đó nhưng thấy khó chịu quá :angry: , bro nào biết password thứ 2 or cách nào đó thì giúp tntanh, thx

nó dùng chip bios cũa hảng nào vây Bro
CmosPwd 4.8
cài ni chỉ dungd c cho máy desktop
Works with the following BIOSes
- 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

If the standard method does not work, then try to kill the CMOS password with CMOSPWD /K (and press Enter), and then see if you can get into the CMOS without a password. If you can, you successfully "killed" the old CMOS password. DO NOT KILL THE CMOS ON LAPTOPS!

On laptops, the password is usually stored in an eeprom on the motherboard,
you need an eeprom programmer (electronic device) to retrieve it.

hic máy you là latop thì mình cũng chả biết làm cách nào đễ tìm cả, cái ni phải có cái máy EProm mà mấy ông sữa bios thì may ra mới đoc dc

Dùng lệnh Debug của DOS (DOS thực chứ không phải trên Windows) để xoá tất cả thông tin của CMOS đi

C:\>Debug
o 70 17
o 71 17
q

Lâu quá không xài nên không biết có chính xác lắm không, bro thử xem.

của tntanh xài Bios Phoenix

cái lệnh debug tntanh nhớ là vậy

o 70 1f (hoặc là ef)
o 71 ff
q

cái này biết nhưng ko dám làm vì dù gì nó vẫn chạy dc bình thường :)

mới chat với thằng s/p thì dc cái này
Philip: Tang, The only way you can remove the BIOS password is by removing and replacing the RTC(Real Time Clock) battery on the Motherboard.
Philip: You need to remove the RTC battery and turn on the notebook. Turn of the notebook and reseat the RTC battery and then turn on the notebook. With this the BIOS settings will be removed and it be back to defaults.

Vậy là sử dụng phương thức cổ xưa là tháo pin
vậy lappy có cái jumper để short không bro

/có 1 số main lúc boot hold phím j hay k j đấy để clear CMOS
1 số hold Insert

:D không sure lắm

[TNTANH]

xong rồi, tưởng phải tháo banh máy ra , nhưng thằng S/p HP gủi cho cái tài liệu, coi xong thì chỉ cần tháo RAM & cái Mini PCI ra
