pls guys solve my problem
i ended up searching this result...
u need to type "powercfg.exe /globalpowerflag off /option batteryicon " then enter,
then "powercfg.exe /globalpowerflag on /option batteryicon" then enter again.
After this go back to properties and under the notification area tab, now the system icons should be selectable.
<SCHEME_GUID> (optional) Specifies the GUID of the power scheme to display, can be obtained by using powercfg -l. <SUB_GUID> (optional) Specifies the GUID of the subgroup to display. Requires a SCHEME_GUID to be provided. If neither SCHEME_GUID or SUB_GUID are provided, the settings of the current user's active power scheme are displayed. If SUB_GUID is not specified, all settings in the specified power scheme are displayed. -CHANGE, -X Modifies a setting value in the current power scheme. Usage: POWERCFG -X <SETTING> <VALUE> <SETTING> Specifies one of the following options: -monitor-timeout-ac <minutes> -monitor-timeout-dc <minutes> -disk-timeout-ac <minutes> -disk-timeout-dc <minutes> -standby-timeout-ac <minutes> -standby-timeout-dc <minutes> -hibernate-timeout-ac <minutes> -hibernate-timeout-dc <minutes> Example: POWERCFG -Change -monitor-timeout-ac 5 This would set the monitor idle timeout value to 5 minutes when on AC power. -CHANGENAME Modifies the name of a power scheme and optionally it's description. Usage: POWERCFG -CHANGENAME <GUID> <name> <scheme description> If the description is omitted only the name will be changed. -DUPLICATESCHEME Duplicates the specified power scheme. The resulting GUID which represents the new scheme will be displayed. Usage: POWERCFG -DUPLICATESCHEME <GUID> <destination GUID> <GUID> Specifies a scheme GUID obtained by using the powercfg -l. If <destination GUID> is omitted, a new GUID will be created for the duplicated scheme. -DELETE, -D Deletes the power scheme with the specified GUID.

Usage: POWERCFG -DELETESETTING <SUB_GUID> <SETTING_GUID> <SUB_GUID> Specifies the subgroup GUID. <SETTING_GUID> Specifies the power setting guid. -SETACTIVE, -S Makes the specified power scheme active on the system. Usage: POWERCFG -SETACTIVE <SCHEME_GUID> <SCHEME_GUID> Specifies the scheme guid. -GETACTIVESCHEME Retrieve the currently active power scheme. Usage: POWERCFG -GETACTIVESCHEME -SETACVALUEINDEX Sets a value associated with a specified power setting while the system is powered by AC power. Usage: POWERCFG -SETACVALUEINDEX <SCHEME_GUID> <SUB_GUID> <SETTING_GUID> <SettingIndex> <SCHEME_GUID> Specifies a power scheme GUID and may be obtained by using PowerCfg /L. <SUB_GUID> Specifies a subgroup of power setting GUID and may be obtained by using "PowerCfg /Q." <SETTING_GUID> Specifies an individual power setting GUID and may be obtained by using "PowerCfg /Q". <SettingIndex> Specifies which of the list of of possible values this power setting will be set to. Example: POWERCFG -SetAcValueIndex <GUID> <GUID> <GUID> 5 This would set the power setting's AC value to the 5th entry in the list of possible values for this power setting. -SETDCVALUEINDEX Sets a value associated with a specified power setting while the system is powered by DC power. Usage: POWERCFG -SETDCVALUEINDEX <SCHEME_GUID> <SUB_GUID> <SETTING_GUID> <SettingIndex> <SCHEME_GUID> Specifies a power scheme GUID and may be obtained by using PowerCfg /L. <SUB_GUID> Specifies a subgroup of power setting GUID and may be obtained by using "PowerCfg /Q." <SETTING_GUID> Specifies an individual power setting GUID and may be obtained by using "PowerCfg /Q". <SettingIndex> Specifies which of the list of possible values this setting will be set to. Example: POWERCFG -SetDcValueIndex <GUID> <GUID> <GUID> 5 This would set the power setting's DC value to the 5th entry in the list of possible values for this power setting. -HIBERNATE, -H Enables-Disables the hibernate feature. Hibernate timeout is not supported on all systems. Usage: POWERCFG -H <ON|OFF> POWERCFG -H -Size <PercentSize> -Size Specifies the desired hiberfile size in percentage of the total memory. The default size cannot be smaller than 50. This switch will also enable the hiberfile automatically. -AVAILABLESLEEPSTATES, -A Reports the sleep states available on the system Attempts to report reasons why sleep states are unavailable. -DEVICEQUERY Return a list of devices that meet the specified criteria. Usage: POWERCFG -DEVICEQUERY <queryflags> <queryflags> Secifies one of the following criteria: wake_from_S1_supported Return all devices that support waking the system from a light sleep state. wake_from_S2_supported Return all devices that support waking the system from a deeper sleep state. wake_from_S3_supported Return all devices that support waking the system from the deepest sleep state. wake_from_any Return all devices that support waking the system from any sleep state. S1_supported List devices supporting light sleep. S2_supported List devices supporting deeper sleep. S3_supported List devices supporting deepest sleep. S4_supported List devices supporting hibernation. wake_programmable List devices that are user-configurable to wake the system from a sleep state. wake_armed List devices that are currently configured to wake the system from any sleep state. all_devices Return all devices present in the system. all_devices_verbose Return verbose list of devices. Example: POWERCFG -DEVICEQUERY wake_armed -DEVICEENABLEWAKE Enable the device to wake the system from a sleep state. Usage: POWERCFG -DEVICEENABLEWAKE <devicename> <devicename> Specifies a device retrieved using "PowerCfg -DEVICEQUERY wake_programmable". Example: POWERCFG -DEVICEENABLEWAKE "Microsoft USB IntelliMouse Explorer" -DEVICEDISABLEWAKE <devicename> disable the device from waking the system Disable the device from waking the system from a sleep state Usage: POWERCFG -DEVICEDISABLEWAKE <devicename> Specifies a device retrieved using "PowerCfg -DEVICEQUERY wake_armed". -IMPORT Imports all power settings from the specified file. Usage: POWERCFG -IMPORT <filename> <GUID> <filename> Specify a fully-qualified path to a file generated by using "PowerCfg -EXPORT parameter". <GUID> (optional) The settings are loaded into a power scheme represented by this GUID. If not supplied, powercfg will generate and use a new GUID Example: POWERCFG -IMPORT c:\scheme.pow -EXPORT Exports power scheme, represented by the specified GUID, to the specified file. Usage: POWERCFG -EXPORT <filename> <GUID> <filename> Specify a fully-qualified path to a destination file. <GUID> specifies a power scheme GUID and may be obtained by using "PowerCfg /L" Example: POWERCFG -EXPORT c:\scheme.pow 381b4222-f694-41f0-9685-ff5bb260df2e -LASTWAKE Reports information about what woke the system from the last sleep transition -HELP, -? Displays information on command-line parameters. -ALIASES Displays all aliases and their corresponding GUIDs. The user may use these aliases in place of any GUID on the commandline. -SETSECURITYDESCRIPTOR Sets a security descriptor associated with a specified power setting, power scheme, or action. Usage: POWERCFG -SETSECURITYDESCRIPTOR <GUID|ACTION> <SDDL> <GUID> Specifies a power scheme or a power setting GUID. <ACTION> Can be one of the following strings: ActionSetActive, ActionCreate, ActionDefault <SDDL> Specifies a valid security descriptor string in SDDL format. Call POWERCFG -GETSECURITYDESCRIPTOR to see an example SDDL STRING. -GETSECURITYDESCRIPTOR Gets a security descriptor associated with a specified power setting, power scheme, or action. Usage: POWERCFG -GETSECURITYDESCRIPTOR <GUID|ACTION> <GUID> Specifies a power scheme or a power setting GUID. <ACTION> Can be one of the following strings: ActionSetActive, ActionCreate, ActionDefault -REQUESTS Enumerate application and driver Power Requests. Power Requests prevent the computer from automatically powering off the display or entering a low-power sleep mode. -REQUESTSOVERRIDE Sets a Power Request override for a particular Process, Service, or Driver. If no parameters are specified, this command displays the current list of Power Request Overrides. Usage: POWERCFG -REQUESTSOVERRIDE <CALLER_TYPE> <NAME> <REQUEST> <CALLER_TYPE> Specifies one of the following caller type: PROCESS, SERVICE, DRIVER. This is obtained by calling the POWERCFG -REQUESTS command. <NAME> Specifies the caller name. This is the name returned from calling POWERCFG -REQUESTS command. <REQUEST> Specifies one or more of the following Power Request Types: Display, System, Awaymode. Example: POWERCFG -REQUESTSOVERRIDE PROCESS wmplayer.exe Display System -ENERGY Analyze the system for common energy-efficiency and battery life problems. The ENERGY command should be used when the computer is idle and with no open programs or documents. The ENERGY command will generate an HTML report file in the current path. The ENERGY command supports the following optional parameters: Usage: POWERCFG -ENERGY [-OUTPUT <FILENAME>] [-XML] [-DURATION <SECONDS>] POWERCFG -ENERGY -TRACE [-D <FILEPATH>] [-DURATION <SECONDS>] -OUTPUT <FILENAME> - Specify the path and filename to store the energy report HTML file. -XML - Format the report file as XML. -TRACE - Record system behavior and do not perform analysis. Trace files will be generated in the current path unless the -D parameter is specified. -D <FILEPATH> - Specify the directory to store trace data. May only be used with the -TRACE parameter. -DURATION <SECONDS> - Specify the number of seconds to observe system behavior. Default is 60 seconds. -WAKETIMERS Enumerate the active wake timers.
