Hi, My Lenovo T400 with Windows 7 Home Premium does not go beyond the first Startup screen when powered On. How much ever we wait "ThinkPad" and the Lenovo Logo will not go away from the screen neither does the laptop go into Sleep mode. Even if we power off the system and then On it after sometime it still is the same. We did discharge the battery completely and then plugged in the AC adapter and power on the system but to no progess. We also removed the Battery, the CMOS battery and the AC adapter for over 30 Sec then replaced all to see if this works but No progess again. Can anyone help Us sort this issue. Thank You. Regards, AJ

Hi AJ,
This is not a hardware related issue. I most probably is related to the operating system. Once the computer is loading up the kernel files and advanced drivers and applications on your computer, it freezes up. To further isolate this, you need to boot the computer to safe mode.
Booting to Safe Mode:
1. Turn the computer on. Start tapping on F8 as the computer is loading up. 2. You should be able to see a black screen with options on it. It is the Advanced Boot Options. 3. Choose Safe mode or safe mode with networking.
In Safe mode, open the system configuration utility.
1. Press the Windows key + R 2. Type msconfig then click on ok 3. Click on the startup tab 4. Click on the disable all located on the bottom 5. Click apply and then ok 6. Restart your computer to normal mode.
If this works you are not done yet. You need to open the system configuration utility and check on the items under the start up tab one by one. You need to find our what program there is causing the computer not to load up. Once identified, You need to uninstall it from your system and your problem is resolved.
