Windows 7 Battery Drain Issues

[SCWolf8609]

Hi. New to the forums, and had an interesting problem I hope you all can help me with. First off System Specs:

Laptop: Dell Precision M4300
OS: Windows 7 RC 64 Bit
CPU: Intel Core 2 Duo T7500 2.20 GHz
Display: NVidia Quadro FX 360M
Ram: 4 GHz (don't know clock cycles)

Alright, now the problem: the battery does not charge anymore. I upgraded from Win XP (clean instal, reformatted the drive during initial installation). The battery worked fine - I didn't time it or check to see for extended battery life, I just knew that when it unplugged from the wall, the battery supplied power and kept it on. After a week or so the battery died. I didn't think anything of it and got a replacement battery. Again, the replacement battery worked for a week or so and then died. The charge icon on the original battery kept telling me there was a problem and the battery would not charge - now the battery icon is stuck at saying 94-95% charged with the replacement. However a quick disconnect from the AC and the lap top goes off. Is there anyway for fix this? The computer also does not go into stand by - indicating that there is not even a reserve charge on the battery, it goes completely off and Windows treats it like an error shutdown by asking if you would like to start in safe mode, yadda, yadda.

Thanks for reading - hope you can help.

Hello Wolf, welcome to the forums! It sounds like you're facing an issue with your Dell Precision M4300 laptop where the battery is not charging properly. The fact that this issue is occurring with both the original battery and a replacement one suggests that the problem might not be with the batteries themselves but with the laptop or its charging system. Here are a few troubleshooting steps you can try to diagnose and potentially fix the issue: 1. Check Power Adapter and Charging Port: - Ensure that the power adapter is working correctly. Try using a different power outlet or adapter to see if the issue persists. - Check the charging port on your laptop for any physical damage or debris that might be obstructing a proper connection. 2. Update Drivers: - Make sure your chipset and power management drivers are up to date. Outdated drivers can sometimes cause charging issues. 3. Reset Power Management: - Reset the power management settings by uninstalling the battery driver and letting Windows reinstall it upon restart. - To do this, go to Device Manager, expand the Batteries section, right-click on each Microsoft ACPI Compliant Control Method Battery, and select Uninstall. Restart your laptop and check if the issue is resolved. 4. BIOS Update: - Check if there is an updated BIOS version available for your laptop on the Dell support website. Sometimes, BIOS updates can address power management issues. 5. Battery Calibration: - Perform a battery calibration: Fully charge the battery, then let it discharge completely until the laptop shuts down. Charge it back to full without interruption. This process helps calibrate the battery percentage readings. 6. Hardware Check: - If none of the above steps work, there might be a hardware issue with either the battery, charging port, or power management system. In this case, it's best to contact Dell Support or a qualified technician for further assistance. Given that you upgraded from Windows XP and performed a clean install when moving to Windows 7 RC, there could be compatibility issues contributing to the battery problem. Try these steps and see if they help resolve the charging issue. If the problem persists, further diagnostics or professional help might be necessary. Let me know if you need more guidance or if you have any other questions!
