Many people were looking how to change the Bios password remotely. Please read my previous post about the Bios settings<\/a>. To set Bios\u00a0password you will need Key scan codes the information about them is also given in my previous post.
\n<\/a>So this is how you do it:<\/p>\n

First we take the script form my previous post<\/a> and slightly modify it.
\n1. The follwing\u00a0script sets the Bios password to ‘password<\/em>‘ on the machine that had not password set.<\/p>\n

Const wbemFlagReturnImmediately = 16
\nConst wbemFlagForwardOnly = 32
\nlFlags = wbemFlagReturnImmediately + wbemFlagForwardOnly
\nstrService = “winmgmts:{impersonationlevel=impersonate}\/\/”
\nstrComputer = “.”
\nstrNamespace = “\/root\/HP\/InstrumentedBIOS”
\nstrQuery = “select * from HP_BIOSSettingInterface”
\nSet objWMIService = GetObject(strService & _
\nstrComputer & strNamespace)
\nSet colItems = objWMIService.ExecQuery(strQuery,,lFlags)
\nFor each objItem in colItems
\nobjItem.SetBiosSetting oReturn, _
\n“Setup Password”,\u00a0_
\n“<kbd\/>191E1F1F11181320”
\nNext
\n<\/em>
\n2. The following script changes the Bios password from ‘password’\u00a0 <\/em>to 123′<\/em><\/p>\n

Const wbemFlagReturnImmediately = 16
\nConst wbemFlagForwardOnly = 32
\nlFlags = wbemFlagReturnImmediately + wbemFlagForwardOnly
\nstrService = “winmgmts:{impersonationlevel=impersonate}\/\/”
\nstrComputer = “.”
\nstrNamespace = “\/root\/HP\/InstrumentedBIOS”
\nstrQuery = “select * from HP_BIOSSettingInterface”
\nSet objWMIService = GetObject(strService & _
\nstrComputer & strNamespace)
\nSet colItems = objWMIService.ExecQuery(strQuery,,lFlags)
\nFor each objItem in colItems
\nobjItem.SetBiosSetting oReturn, _
\n“Setup Password”, _
\n“<kbd\/>020304”, _
\n“<kbd\/>191E1F1F11181320”
\nNext<\/em><\/p>\n

3. The following script removes\u00a0Bios password. In order to remove the password you still have to know what it is. In this case it is set to ‘password’<\/em><\/p>\n

Const wbemFlagReturnImmediately = 16
\nConst wbemFlagForwardOnly = 32
\nlFlags = wbemFlagReturnImmediately + wbemFlagForwardOnly
\nstrService = “winmgmts:{impersonationlevel=impersonate}\/\/”
\nstrComputer = “.”
\nstrNamespace = “\/root\/HP\/InstrumentedBIOS”
\nstrQuery = “select * from HP_BIOSSettingInterface”
\nSet objWMIService = GetObject(strService & _
\nstrComputer & strNamespace)
\nSet colItems = objWMIService.ExecQuery(strQuery,,lFlags)
\nFor each objItem in colItems
\nobjItem.SetBiosSetting oReturn, _
\n“Setup Password”, _
\n“<kbd\/>”, _
\n“<kbd\/>191E1F1F11181320”
\nNext<\/em><\/p>\n

This only been tested on HP laptops and desktops(nc6400,nc6220, 6910p, dc7600). Also HP CIM<\/a> must be installed.<\/p>\n
