Using 27++ battery with Thinkpad T510

2011-03-26, 8:41 AM

Hi,

 

I have just purchased a T510 with the 27++ slice battery, the battery "User Guide" is anything but !

 

Can someone please tell me whether there are any restrictions on when I connect & disconnect the slice battery?

i.e., can it be plugged and unplugged without powering down, hibernating or sleeping the Thinkpad?

 

For the battery to be useable, I'd certainly hope so, but as it connects to the docking connector, I'd like to know for sure before I do it for the first time.

 

As an aside, I have also just read that if you unplug the slice with the Thinkpad in sleep mode, even with a fully charged normal battery connected, the laptop goes to a power off state. - has anyone here seen that?  Can it be corrected?

 

regards

Dave

Hallo,

as no separate instructions for replacing the battery follow with the slice battery, check the Access Help User's Guide for instructions. If it doesn't offer special instructions for the slice battery, i suppose that its general instructions for replacing the main battery are better than nothing. For my notebook, which isn't a T510, the Access Help User's Guide says: turn off or hibernate the notebook, disconnect the AC adapter and all cables. Install or remove the battery. Then, connect the AC adapter and all other cables.

 

The Safety and Warranty Guide for your notebook gives some additional information on disconnecting and connecting cables to the notebook. It says:

 

Connect and disconnect cables as described in the following procedures when
installing, moving, or opening covers on this product or attached devices.


To connect:
1. Turn everything OFF.
2. First, attach all cables to devices.
3. Attach signal cables to connectors.
4. Attach power cords to outlets.
5. Turn devices ON.


To disconnect:
1. Turn everything OFF.
2. First, remove power cords from outlets.
3. Remove signal cables from connectors.
4. Remove all cables from devices.


The power cord must be disconnected from the wall outlet or receptacle before
installing all other electrical cables connected to the ThinkPad® computer.


The power cord may be reconnected to the wall outlet or receptacle only after all
other electrical cables have been connected to the computer.

Generally, hot plugging the battery should be okay.

Here are a couple guidelines.

 

If you are running on battery power while in 'on' or 'standby' state and the notebook is being powered by the slice battery (not the main) and you remove the slice battery, the system will power down. You are basically removing the current source of power. If you are in Hibernation or off state then you can remove it with no worries.

 

If you are running on battery power, and the energy in the slice battery is depleted so that the system is being powered by the main battery, you can then remove the slice battery without issue.. .but not the main.
