Why is my Thinkpad blinking?
Normally this flashing means the Lenovo laptop is in sleep or standby mode, in which case just press any key to wake it up.
What is the red light on Thinkpad?
If the red dot is lit, it is probably on/suspended. Sometimes laptops get stuck in suspend mode. Pull the battery, unplug AC power, and wait about a minute for it to completely lose power (the red dot should turn off). Then replace the battery and plug it back into AC, and try turning it on again.
When I turn on my Lenovo laptop the screen is black?
Solution. Press the Windows key + Shift + Ctrl + B at the same time. This should bring the screen back.
Why is my computer blinking and not turning on?
A laptop power button can keep blinking but not turn on because of a BIOS or CPU failure. One reason for the laptop power button blinking but not turning ON could be due to a battery that is about to die. If the battery is working below the required level, then the system will not power ON completely.
