Dell laptop forced to be slow when charger cable defective or battery removed altogether or battery is fried/at end of its life. I have a Dell 5559. Its charger is ok but the charging pin perhaps is defective now. So, when i boot up, it slows down the PC right from the get go. POST time message says "The AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available." When windows load, i can see PC Is locked to 400MHz. Now i can use throttle stop to overclock the CPU and make it run at optimal potential. But this is very inconvenient because i need to restart pc frequently and every reboot costs me 5 minutes at least. Besides, i use linux intermittently. Can anyone disable charger/battery detection in bios modding or at least make sure computer wont slow down due to alleged AC adapter incompatibility?
I looked into rar file and saw that, but hoped it could be worked-around. But it is not. Thank you anyway.
