So I got a laptop yesterday from a local pen shop it said "doesn't hold charge" I brought it home and it displayed a "AC power adaptor wattage and type cannot be determined" message and wouldn't load up windows, I tried to reinstall windows and still errors, I have a new battery adaptor and it seems to be charging now but still no luck, I decided to use a program to erase everything off the computer and reinstall windows and when windows is setting up it stays stuck a 0% I'm so lost.

Please post make/model

--- The correct AC power adapter needs to be determined 

 

Also is the computer OS already Windows 7 or are you trying to do a Windows 7 Upgrade?

--- What was on the computer before you erased everything?

--- Did you back up anything or create an image onto external media?

 

Just to verify

Since you were able to erase everything off the computer and attempt to reinstall windows, you are doing so with the laptop directly plugged into an electrical outlet

You are using a new battery adapter that seems to be charging

--- Is this new battery adapter designed for your laptop?

It is a Inspiron 1440, I have the same kind of charger so I'm using that, it charges now but won't let me reinstall windows, hell I even tried running KILLDISK to erase everything and start from scratch but not working, idk what was on the PC This is how I got it, actually with just that charger warning. Yes the laptop is still directly plugged in

"AC power adaptor wattage and type cannot be determined" means you are using a power supply that is too weak for your laptop. Buy the right one.

You are probably already doing this but I can't assume

--- Please remove the battery 

--- Go into the BIOS and ensure the time is correct

--- I would also consider replacing the CMOS battery

Then try installing Windows 7

--- Report the exact error message and what step it happens at

We still do not know whether or not the original OS is Windows 7

--- The reason I mention that is, if it isn't Windows 7, there can be driver/incompatibility issues

--- Also since you cannot run the Windows 7 Upgrade Advisor, driver/compatibility issues cannot be determined

BTW, what is your Windows 7 install media?

--- Is it an install disc that came with the computer?

--- Is it one you purchased yourself?

 

On the AC power adapter, you need to ensure it's the correct one for your Inspiron 1440 

--- Using a same kind of charger needs better description to determine if it's the correct one for your Inspiron 1440

Dell laptops use 3 different AC power adapters. 120Watt, 90Watt, 65Watt.

 

Your Inspiron 1440 uses a 90Watt adapter. Using a 65Watt will not only degrade performance, but also cause long term issues.

 

It is recommended that you purchase the proper AC adapter (90Watt).

 

In the meantime you can go into the BIOS by pressing <F2> and go to the Advanced Screen, toggle to Adapter Warnings and change to Disable.

 

Save your changes and exit.
