T60 completley dead after batttery discharged

[fallingleaf]

Hi all,

I left my T60 turned on overnight and forgot to plug it in.  When I discovered it in the morning I plugged it in and it would not start.  Not only that, but I don't even get the led indicating that it is plugged in to AC power.  As far as I remember I had it set to hibernate when the battery gets low, but I have never tested to see that it  actually does.

I have tried everything on the troubleshooting page.  Also I have tried this business of pressing the power button ten times and then holding it down for 30 seconds.  Anyone had this problem before?  I found similar things on the forums but none of the suggested fixes have worked. The only thing I haven't been able to try is putting in a known charged batterybecause I don't have access to one.

so trying to power on laptop without Battery with AC only don't work either??? Do you still have warranty?????

[fallingleaf]

Yeah, I've tried every combination of things.  Battery only, AC only, both AC and battery.  Yes, I still have warranty.  I finally got a response to my email support request and they told me it is the system board and to me to contact the warranty service.  I am in Costa Rica, but I bought the laptop in the US, so I don't know if they will fix it here.  Also, Lenovo lists Costa Rican support as Spanish only and my Spanish is not the greatest.  I'll give them a call and hope they have an english speaker there.

Also it seems really weird that it would be the mainboard.  I mean, it's very coincedental that the board would decide to die just when I happen to leave the machine running on battery overnight for the first time.  Seems to me there ought to be some stupidly simple fix like some sort of reset button or something.

Thanks fo rthe reply BTW.

I have a T61 (T60 might have the same issue, take a look)  and after reading all the forums I ended up taking the BIOS battery and the main battery out and leaving only AC power plugged and caaabang it started I was so happy. After putting everything back together I turned on the power and set the bios settings to correct date and time. Windows showed loading and I was back in as a happy camper ) But once I shut down I could not turn it back on again without unplugging the cmos battery, that lead me to believe that there was a short somewhere so after dusting everything out with compressed air and cleaning everything with an anti-static cloth I was able to narrow down the problem... the freaking docking port was oxidized but you can' tell unless you press the little plastic cover down!!! I got some rubbing alcohol and equipment cleaner and proceeded to clean the  port out, once complete I took the bios battery out one more time, and put it back in and ever since I have not had a problem starting the thing up. Hope this helps to those that are looking for one more solution to this problem.

Cheers, Nick.

ok, on my laptop (t42p) it MIGHT have the same problem, it seemed like the motheroard is screwed over, i had it in my laptop bag, it was on, i had the laptop charging, and then the laptop shuts off,i check the plug, its fine, which led me to think that the mobo was bad, but i never had a problem with it before, BUT my laptop did start slowing down significantly (even with linux, i have reinstalled the os), did any of you experince any slowing down of the system.
