DOCUMENT:Q263240 17-DEC-2000 [win95x] TITLE :PRB: Tab Disappears from Power Management Properties on IBM Thin PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:Win2000:95 OPER/SYS: KEYWORDS:kbHWx86 kbOEM ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== Windows 95 does not allow the Control Panel Power Management application to display more than eight tabs at a time. The ninth tab is not displayed on the Power Management application if original equipment manufacturers (OEMs) and/or independent hardware vendors (IHVs) add their own custom tab. CAUSE ===== Windows 95 removes (or hides) any tabs that are installed after the eighth tab. This problem has been verified after installing a Xircom CE2 performance series cardbus card on a Windows 95-based computer, which adds a new PC-Card Modems tab to the Power Management application. When this new tab is added, one of the eight tabs that were previously visible is removed. STATUS ====== This behavior is by design. Windows 95 was not designed to support more than eight tabs at the time the product was released. This limitation has been corrected in Microsoft Windows 98 and later. MORE INFORMATION ================ Steps to Reproduce the Problem ------------------------------ 1. Install Windows 95 OSR2.1 on IBM ThinkPad 600X with Intel SpeedStep Technology processor installed. 2. Install Internet Explorer 5, which is a prerequisite of ThinkPad Configuration Utility, and then restart the system. 3. Install all relevant device drivers, and then restart the system at each installation of a device driver. 4. Install ThinkPad Configuration Utility, and then restart the system. 5. Open ThinkPad Configuration Utility. 6. Select Power Management (click the battery icon), which should open the Control Panel Power Management application. 7. Confirm that seven tabs are displayed on the Power Management properties (Power Mode, Suspend resume option, Alarm, Power Management, Disk Drives, Hibernation, Advanced Setting). 8. Close the Power Management properties. 9. Install the Intel SpeedStep application, and then restart the system. 10. Open ThinkPad Configuration Utility, or open the Power Management application in Control Panel. (Select Power Management to open the Power Management application.) 11. Confirm that eight tabs are displayed on the Power Management properties (Power Mode, Suspend resume option, Alarm, Power Management, Disk Drives, Hibernation, Advanced Setting, Intel SpeedStep Technology). 12. Close the Power Management properties. 13. Install any PC Card to the system, for example, a PC Card Modem (Xircom CE2 Performance series cardbus card). 14. Open ThinkPad Configuration Utility (or, open the Power Management application in Control Panel.) Notice that the PC Card Modem tab, which is one of the Windows 95 standard tabs, has been added and is displayed. However, one of tabs that was previously available is missing. In this case, the Intel SpeedStep Technology or Power Mode tab disappears.
