Can't switch on Lenovo T61 laptop

[gbohnke]

updated my T61 to windows 10 no problems. Used it for a few month updated and everything run well. Then one day I switched it of put it in a drawer under the Table and since then Ican't switch it on again. Battery is full. plug on to the Charger, nothing.
Is it Time to get rid of it?

Hi,

Please do try these troubleshooting steps first that I suggested to others who had the same concern.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.

Since it is a pretty old laptop, my guess is that the CMOS battery is dead and needs to be replaced. Once it is replaced the laptop should boot up unless there is something else that has deteriorated and needs to be replaced / repaired.
