T410 Will Not Start

#1 Post by chuck6209 » Sun Mar 17, 2019 8:19 am

Had trouble with start button, tried various suggested fixes with no results. Replaced CMOS battery, plugged in adapter and laptop turned on. Seemed to work fine. Shut down and it would not turn back on. Tried unplugging and replugging CMOS battery but no results. One week later plugged in adapter and it turned on. Unplugged from adapter and it was running on battery. Closed up laptop and it went into sleep mode but would not wake up, start button ineffective. Was able to restart once since then by plugging in adapter but now that method no longer works.
Any suggestions would be appreciated as I don't need another paperweight

Remove power and battery, then hold down power button for ca. 20 seconds.
Plug in power only, try to boot.
If OK, add battery.

Thanks for your reply. This process did not work. However, I did unplug the CMOS battery, plugged in the AC adapter and the laptop went to f1 for setup. I reset time only as date was correct and saved and Windows started.
This is an interesting way to start a laptop but not very convenient. Can anyone tell me, based on this most recent experience, what is going on?

Update: Laptop will only start when CMOS battery is unplugged and only by plugging in AC adapter. Will not start with start with start button. Plugging in CMOS battery while laptop is running has no effect.

Have you tried with a different keyboard yet? Or with the dock power button?

RE: 410 not starting, I had this issue and found a tip online. First remove battery and wait one minute. Reinstall the battery then press the start button (13 ?) times and hold on the last one. Mine booted right up! Sorry I can't remember the number of times, but is was 11 or 13; not sure how critical that is. I found it on the Lenovo website, I believe. In any event, it brought my dead screen to life, and it's been working ever since. Good luck!

Thanks. That was one of the things I tried before posting here.
A recent response to my post suggested trying a dock or a new keyboard. I bought a dock on eBay and that solved the startup problem.

Seems like your keyboard power button is broken. A replacement keyboard may solve it as well.

Don't want to spoil your fun, BUT:
what you NEED to do here, is to reset the laptop.
In order to do so, it needs to be fully DISconnected from AC and battery! (CMOS should not be needed).
Instead of pressing numerous times on the power button, it is sufficient if you press only once and hold that power button down for ca. 20 seconds.
This drains any leftover electricity from the laptop's capacitors.
If there are no other problems, add AC and boot.
