Before Servicing The Computer; 1010 External Battery Pack - Lenovo ThinkPad T440p Hardware Maintenance Manual

Before servicing the computer

Some models you are servicing might have a SIM card that a customer has installed. If the computer you are
servicing has a SIM card installed, remove it before you start the servicing.
To remove the SIM card, do the following:
1. Turn off the computer, then disconnect the ac power adapter and all cables from the computer.
2. Remove the battery. See "1010 External battery pack" on page 56.
3. Locate the SIM card slot inside the battery compartment, and then gently pull the card out of the slot.
After you finish the servicing, ensure that you install the card back into the SIM-card slot firmly.

Important notices for replacing a battery pack
Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
The Lenovo Solution Center program provides an automatic battery diagnostic test that determines if the
battery pack is defective. A battery pack FRU should not be replaced unless this diagnostic test shows
that the battery is defective. The only exception to this is if the battery pack is physically damaged or a
customer is reporting a possible safety issue.
If the Lenovo Solution Center program is not installed on the computer, the customer should download and
install the program to diagnose the battery pack, before getting a non-physically damaged battery pack
replaced. Note that the replacement of a physically damaged battery pack is not covered by the warranty.
