T440S sometimes won't boot unless i detach che internal battery

#1 Post by pictux » Fri May 19, 2017 9:36 am

Hi everybody.
My t440s has now this annoying problem.
Sometimes (i mean: every 2 days or so) it won't boot.
Not only, if i attach the power cord, nothing happens (usually attaching the power cord, the red led blinks 3 times).
It seems dead.

I try removing external battery, pressing the reset switch for the second (internal) battery, pressing and releasing the power on button, but without success.
The only way to resume the laptop, is opening it, and detach and reconnect the connector of the internal battery.

Now i'm working with the connector detached, to avoid every time the need to open the case in order to boot the laptop :)
What do you think?
Battery seems ok (the charge is the usual), and once reconnected the laptop boot without problem...

Any suggestions?
Thanks

Buy a new batt and try, maybe ur battery is internally shorted??

Hi and thanks for the reply.
I don't think the internal battery is shorted, because after i detach & reconnect it, it's recognized correctly and it works...
Am i wrong?
Thanks

update: it has started with the same issue with the removable battery.
I have to remove it, press the boot button for a few seconds, and then reattach it.
Than i can boot my laptop.

As i've already said, batteries are charged when the power plug is inserted, and i've the usual power autonomy when running on batteries.
So they seem ok...

Any suggestion / tip?
Thanks,
M

Try another (more powerful) charger.
Or if you have it, use an adapter cable such as this: http://www.ebay.com/itm/361863732964 with an older 65W/90W charger.
Wild guess: maybe switch off "USB always ON" in BIOS.
Have you checked that none of your USB ports is broken?

Hi and thanks for the reply.
I've switched off "USB always ON" in BIOS, but nothing has changed.
USB ports seem all ok (i've tried with an usb key and a mouse)-
Just curious: how'd the charger affect the computer in this way?
Thanks

It would give the computer mpre power to use between charging both batteries and running the computer.

At this point, I'd make sure I was on latest BIOS. I would try detaching the CMOS battery and all other power sources. If it still keeps doing it as much as I hate to say it the board could be getting flakey in that area. It could have experienced some kind of damage or moisture. The mother board in my T450 which experienced lemonade behaved in similar fashion in addition to other things like shutting off just after boot up.

The good thing is that these boards are pretty easy to replace. The bad thing is that they are a lil more costly due to CPU and RAM being soldiered on. I got my board from ebay for 200 bux.

If it's not shutting off on you or corrupting data you could probably just get by with it since it is just an annoyance.

Hi guys, new update.

So, i've detached the internal battery, so i'm not using it anymore (sob).
To power on the thinkpad, i have always to remove the main battery, and then replug it. Don't need to press the power button in the between.
After that, i'm able to turn on the laptop.

I've tried the battery from a new t450 (that is the same) but the behaviour is the same. To turn on the laptop i have to do the remove-replug trick.

Don't know: maybe it's time to change laptop?

Hi and thanks RealBlackStuff!

I've read here as well:

"I had a similar problem with my X220 after spilling coffee on the keyboard. It would only power up after disconnecting all batteries. But it would only do this one time. Replaced the keyboard and problem solved. "
so it can be that: the keyboard!
I'm gonna give it a try! (finger crossed)

Thanks
M

EDIT: just ordered a new keyboard.

EDIT: new keyboard arrived and installed.
Now my T440s has a new fresh look. But the issue is not closed. I still need to remove the battery in order to turn on the laptop :(

Hi, after looking at your thread, I believe I have the exact same problem as you, the laptop would sometimes die in standby and won't turn on unless I opened the case and unplug the internal battery. I don't know if this is a motherboard issue or something else. Have you found a solution yet?

I have removed the internal battery permanently and replaced the external with a more recent model.

The problem persists. However it is less frequent than before. Also it is more easily resolved as it is easier to remove and reinstall just the external battery.

Hi,

> I have removed the internal battery permanently

i've done exactly the same.
The issue is not addressed yet, i'll try changing the memory bank (don't know if can help, but at this point who knows).
Cheers
