My T440 has been working without issue for a few years, but recently it left to go to sleep and it would not restart... appeared completely dead. Plugged in the AC and got the 3 LED flashes at the power button, but still nothing... no power.
After reading other posts I ended up opening up the case and disconnecting the internal battery and the CMOS battery, reconnecting them, close it up and plug in the AC and it's working again once I update the time settings in the BIOS.
I have since update the BIOS to the latest version, fully charged the batteries and used the Lenovo tools to check the system and all reports good including the batteries, but it's still having issues
Obviously this is not ideal and I would like to resolve/fix whatever the issue is?
PS - The reset hole on the bottom doesn't work

Welcome to the Lenovo forum discussion!
We recommend contacting the Lenovo Think Support at 1-800-565-3344 and inquire for a complete diagnosis/repair service as this could be a possible hardware malfunction with the laptop.
Alternatively, you can bring the laptop to a service provider https://support.lenovo.com/us/en/solutions/ht118678?CID=ww:lenovosocial:20x9m6 (filter by country) and inquire for a warranty service. We hope everything will turn out smoothly.

My T440s has been perfect from the start (2014), but now it either won't start or will start and goes as far as the user icons to click. I have gone through all of the posts for this problem and acted upon the following:
1. Removed the battery pack and pushed the reset button for 5 seconds. Result: nothing.
2. With the battery pack removed, I opened the case and unplugged the internal battery. Then I plugged in the external power supply and tried unsuccessfully to start the computer. Next I unplugged the external power supply, replugged the internal battery, closed the case, put back in the ext. battery pack and put it on the dock this time (in case there might be a problem with the ext. power supply). The computer started normally with its sounds and pictures until it came to the icons for entering the user programs. At that point it went dead. The ON"button blinked several times and went off. It would not come back on.
At this point I am out of options. Any more suggestions? Please! I am on an old and sluggish Dell with XP and hope I can receive an email if anyone replies. Thank you.

Try hitting F10 at startup to get to built-in diagnostics.
