Question about Dell Inspiron 1501 Notebook

2 Answers

I had the battery not recognized on boot up. then

I had the battery not recognized on boot up (dell inspiron 1501 bios 2.6.1). then the ac adapter stopped giving ac power. i changed to a different adapter (hp notebook) and now only works on ac power (it doesn't charge the battery). i updated the bios (version 2.6.3) and now get the ac adapter not recognized msg. additionally the original adapter doesn't show the green light it used to when plugged into an outlet. any thoughts on trying to salvage the original adapter vs modifying the one that runs on ac power only vs getting a new dell adapter? thanks in advance for your help.

The Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

Error code 3600:0749 dell inspiron 1501 . Result is the same if it runs on battery or AC alone (no battery in laptop).


Check the system battery information and charger information of the computer restart the computer, while the computer is booting up, press F2 repeatedly check "battery info"
If it stated ac adapter = unknown device update the BIOS
Click on drivers and downloads
Click or choose by service tag
Download the BIOS and install it on the computer
Check information after updating if same message AC adapter = unknown device; call manufaturer for a replacement AC adapter, if status has changed it is a battery problem or motherboard, contact manufacturer to test battery.

The adapter could be faulty or has failed slightly and is below the operating limits. This means you probably need to replace the power adapter.

Dell inspiron 1501 cannot indentify ac adapter


try this first. drain the flea power. remove batter and ac adapter. press and hold on the power button for 10 seconds. plug back ac adapter and battery. go online to http:support.dell.com then download the latest bios update.

once you reach the dell support site select on support for home users. then drivers and downloads. enter the service tag.

when the list of drivers and updates are listed make sure you selected the correct operating system. look for the BIOS then download it via browser. (do not download the manager)

after the download run or install the update.

If all fails. try a diff ac adapter if same problem message appears then replace the motherboard. else replace ac adapter.

Dell Inspiron 1501 will not boot with battery or adapter


Take the battery out and try with AC only, if no change, then you will likely need a motherboard replacement

Dell inspiron 1501 work fine turn off last night now wont turn on


You mentioned trying a different battery, try a different AC adapter.

When plugging in the ac adapter to the wall, see if the POWER LED comes on on the adapter, then when you connect it to the computer, see if the LED stays on.

If the issue occurs with both AC adapters (No battery installed) then the motherboard has failed. If one ac adapter works but the other doesn't then the adapter is bad

Replacement battery for Dell Inspiron 1501 won't charge


If your old battery was doing the same (not charging), then is is because the charger is not charging the battery. Do you have a friend with a Dell laptop? Maybe you can use a borrowed charger to test and see if it will charge the batteries. To answer your question , no Dell does not have anything built in to prevent you from using a 3rd party battery.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
