T61 won't boot up

I have a T61 (type 7658 CTO) that suddenly fails to boot up. Prior to this, it turned on normally and was left on for about an hour. Sometime during that hour the laptop shut itself off. There was still a charge in the battery and it was plugged in to a power supply. Shortly after starting up there was a popup message saying that a Lenovo update was available but this message was ignored and not acted upon.

The only LED indicator lights that now work are the one indicating that it is plugged into a power supply and the one that indicates the battery is in use or charging. If the power switch is pressed, both of these LEDs turn off. Nothing else happens and the only way to get these two LEDs back on is to remove the battery and power plug and then reconnect both of them. No other LEDs turn on at any time and the hard drive is not active.

Re: T61 won't boot up

Hello mate,


Sound like a hardware problem. I don't know what graphic card you've got in your computer but if you have the Nvidia Quadro NVS 140M it could be dead. Nvidia had a lot of problems with these chips. As they part of the main board, if your Thinkpad is not under warranty is game over.


Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it.

ThinkPad T510 4313-CTO Windows 8 x64 - Intel Core i7-620M - NVIDIA NVS 3100M - 8GB RAM - 240GB SSD- Intel Centrino Ultimate-N 6300 - Gobi 2000.
ThinkPad Helix 3697-CTO Windows 8.1 x64 - Intel Core i7-3667U - Intel HD Graphics 4000 - 8GB RAM- 256GB SSD - Intel Centrino Advanced-N 6205 - Ericsson C5621gw

Re: T61 won't boot up

All the 7658 boards are Intel, not nVIDIA. Pull the main battery and unplug it. Press the power button several times, holding it for a full 5 seconds on the last time. (That will drain capacitors and completely reset) Put the battery back in; plug it in and tyry again.

I do not respond to requests for private, one-on-one help. Your questions should be posted in the appropriate forum where they may help others as well.

I am not an employee or agent of Lenovo.
