so, i let my parents borrow my laptop to watch a movie, and then i came back, and found out that the 3rd LED on my laptop, a N5010 inspiron, flashes 4 times amber, then pauses on white and repeats.
i did look up the question on Google, turns out it has something to do with the laptop not recognizing the battery pack.
one suggested to take the battery out, and clean the terminals. i tried so, but no avail.
however, the battery itself still works, it flashes when plugged and unplugged from the charger. i cannot tell if it charges or not.
see, i used this laptop as a desktop, left it plugged in all the time.
the true time that my battery will last is unknown.
it is running windows 7 and is fully updated.
Thank you for writing to us. Please check if the ac adapter is detected in BIOS follow the steps below.
Shut down the computer and tap F2 during the startup > default BIOS page will be ‘Main’ in that page check the Ac adapter type is 65W/90W/130W. If the adapter is detected in BIOS, Kindly update the BIOS using the link bellow.
In this link punch in the system service tag or express service code and select the appropriate operating system, under the BIOS category select the latest BIOS and install it.
Connect the Ac Adapter before updating the BIOS and do not use the system until it restarts after the update.
Please let me know if this helps.
sorry for the very late reply.
it took me some time to understand where you wanted me to look on the boot menu....
but i did find it.
it shows the ac power is 65W.
i tried updating bios but it gave me an error:
"Cann't flash to the same Bios version. Press OK to exit. "
yes it actually says "Cann't"
Please send me the system service tag or express service code through this private chat, I will see what best can be done.
