Hi all,
I was asked by a friend to look at his Dell Inspiron 1525 Laptop. He can’t get past the sign-in screen using Vista Home Premium.
Dell wants $70 to just take possession of it. Needless to say he was hoping I could determine the problem.
Now it no longer goes to the sign-in screen but instead gives the following message:
“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.
Please connect a Dell 65W AC adapter or greater for best system performance.
To resolve this issue, try to reseat the power adapter.
Strike the F3 key (before the F1 or F2 key) if you do not want to see power warning message again.
Strike the F1 key to continue, F2 to run the setup utility
Press F5 to run diagnostics.”
The power supply is in fact a 65 Watt Dell power supply that came with the unit. The power supply does in fact provide power by indicating the green pilot light on the brick. Also the screen pops up brighter as the power supply is plugged in.
Pressing the F1 key goes through the diagnostic with the following results:
Error code 3600:0749
Msg: AC_ADAPTER – Invalid AC adapter detected
Error Code: 0F00:075D
Msg: DISK_0 – Self-test Read Error
Pressing the F2 key only brings me back to the same message screen.
Ok, the problem and solution seem obvious, but I know from experience error codes don’t always tell the true cause or problem but only the symptom of another problem (kind of like the check engine light on cars).
My question is…do you think the power adapter is in fact defective or could the battery be defective? And will this cause the starting problem? The hard drive error does not concern me because I think that’s from repeated restarts without proper shut downs.
Can you suggest any other steps short of sending unit back to Dell?
Additional info…Can’t start in Safe Mode, all other diagnostics pass including memory, it’s possible to enter the Bios and make changes.
Thanks to any or all who reply.
