My system won't turn on only showing charging light

Hi @abdullahia21731

Try a full power refresh in case it is a corrupted BIOS and check if that resolves the problem.

Here’s the procedure:

a). Disconnect the charger from the laptop if connected.

b). Remove the main battery from the laptop.

c). Remove the RTC (Real Time Clock) battery from the motherboard. This battery is also known as the cmos battery or the backup battery)

Here’s the hardware maintenance manual for the laptop. Go to p.76 to view the necessary pre-requisite steps and then the procedure to remove the RTC battery.

When the RTC battery is removed measure its voltage. If it is <2.6V DC replace it. Search online for Lenovo R61 cmos battery to find suppliers tat suit you best.

d.) Reconnect the RTC battery (or its replacement).

e). Reverse the above steps to re-assemble the laptop.

f.) When the laptop is completely re-assembled, connect the charger and try to turn on the laptop.

If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.

If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.
