I have a Dell Insperion 1501 that has been running great. Suddenly the AC adapter is not recognized and will not charge the battery.

No changes had been done to it except to update the system from Windows Updates. I have done some research and everything points to this being a BIOS issue. My only problem is that the BIOS will not update. I am logged in as the system administrator and it denies the update.

Any pointers or options?

A Phoenix Winphlash window opens up stating "Cannot load driver C:\Users\Desktop\PHLASNT.SYS, Pease check your accounts, if you have no administrator privilage, please login again.
Access is denied.
Error code: 5

I am logged in as the system administrator.

After this is done then I get several files on the desktop.

WinPhlash, MFC42.DLL, MSVCP60.DLL, and PHLASHLC.DLL. There is also a PHLASH Help but that has not been any help.

Update:

Took the computer to Best Buy and asked them to plug a new cord into it and verify that the issue was not in the comp. It is the ac adapter that is the problem.

In my research for this issue there were 3 possible problems that I could understand. One is the adapter just went bad, there is supposedly a chip inside the adapter that can be replaced and that is for those who are more skilled at those type of repairs. The second is that there is a chip inside the laptop that can be replaced. The final issue is, what I was trying to resolve, a BIOS error and would need to be flashed.

Thanks for the help to get me to a point that made me aware that it was not what I thought it was.
