Lenovo laptops are becoming more and more common because of their portability, convenience, and even affordability. But every now and then you may encounter a problem with the laptop that causes it to freeze or even turn off. One of these problems is the power button flashing lights on your Lenovo laptop not turning on.
If you experience your Lenovo laptop power button flashing or blinking three times when turned on, it’s a sign that your laptop is in sleep or standby mode. Press and hold the power button for 15 seconds to snap it out from sleep mode, and the flashing light will cease.
The Lenovo laptop, like most gadgets, works perfectly when new but develops glitches like blinking the power button when turned on. Most users complain that they have issues removing their Lenovo laptops from sleep or hibernate mode. This guide has all the details you need for troubleshooting the blinking power button light on Lenovo systems.
Why Is My Lenovo Power Button Flashing And Not Turning On?
If you realize your Lenovo laptop power button flashing but not turning on, the glitch could be from the laptop battery or other external components. Low voltage supply from the A/C Adapter is a possible reason your laptop isn’t turning on even when it’s connected to power.
The following are common issues that affect Lenovo laptops turning on:
Battery Or A/C Adapter Fault
The laptop battery provides external electricity that powers the other components in the system. If the battery is old or damaged, it’ll affect the laptop’s booting process. The power button may blink a couple of times, but the laptop doesn’t turn on.
The charging port can get faulty and causes issues with turning on the laptop. A worn-out charging port will not connect properly with the A/C Adapter. In this case, the laptop will not get enough power to turn it on. Replace the battery and fix the charging port as the case demands.
Your laptop may be connected to a power outlet but doesn’t turn on because it’s not receiving enough voltage. The A/C Adapter delivers the voltage your laptop needs for charging. If the adapter power cord is faulty, it’ll supply improper voltage.
Poor voltage affects how your laptop boots. To confirm that the A/C Adapter is damaged, use it to charge another laptop. If it doesn’t work, then the issue is the A/C Adapter.
Most people already know that overheating isn’t healthy for laptops, but only a few are familiar with the consequences resulting from overheating laptops.
The Lenovo laptop’s internal hardware is delicate. It’s designed with an internal thermal protection system to prevent heat-associated glitches. If the laptop is overheated, the thermal hardware system shuts down the laptop automatically.
Some of us are fond of putting our laptops directly on the bed while using them in the bedroom. Doing so can block the laptop’s air vent and cause heat to build up, and the thermal system reacts. If you try booting the laptop in this condition, the power button may blink, but the laptop doesn’t turn on.
Sometimes, the issue with the laptop is something as common as shutting down the laptop. Turning off your computer while there are running apps or tasks in the background can cause your laptop to act up when you’re turning it on.
An underlying issue like bad hardware components in the laptop can cause a flashing power button when you turn on the laptop. In this scenario, the power button blinks when connected to a power outlet but doesn’t turn on. A common cause is a faulty hard drive. Consider replacing the hard drive with a new one but contact an expert, so you don’t make mistakes.
How Do I Stop My Lenovo Power Button From Flashing?
Your Lenovo power button flashing means the laptop is in hibernate or sleep mode because you closed the laptop lid, left the screen idle for a long time, or you put it in sleep mode. To stop the Lenovo power button from blinking, follow these steps;
Solution 1: Wake The Laptop From Sleep Mode
- Open and close the laptop lid three times. By doing this, you’ll remove it from sleep mode.
- Alternatively, press the power button, Fn key or windows key and the laptop will wake up.
If this doesn’t stop the blinking power button, proceed to the next solution.
Solution 2: Hard Reset The Laptop
- Press and hold the power button for 15 seconds to turn off the laptop.
- Turn the laptop back on.
- If the power button light is still flashing, but there is no display on the screen, proceed to troubleshoot.
Solution 3: Reset BIOS Settings
Sometimes, the settings on the Lenovo laptop can get corrupted. If this happens, the power button light will blink or flash while the screen remains blank.
To reset the BIOS to default;
- Open the laptop shell at the bottom
- Remove the RTC battery and the battery pack.
- Let the battery cool to room temperature.
- Place the battery pack and RTC battery back in.
- Connect the Lenovo laptop to power and boot the system.
Solution 4: Laptop Display Screen
If the Lenovo laptop display screen is faulty, the laptop power button may flash three times, but the display screen is blank. This will give you the impression that the laptop is off.
To confirm the issue is from the screen;
- Press the power button to turn on the system.
- Listen for the fan noise produced while the laptop is booting.
- If you’re sure the laptop is on but there’s no display, the screen is faulty and should be repaired.
Lenovo Laptop With No Status Lights?
If your Lenovo laptop is plugged into power, but the status lights are not coming up, it can be caused by an internal problem like residual power or an external problem like a faulty A/C Adapter. Lenovo laptop users experience common glitches like this when turning on their laptops.
After updating BIOS on your Lenovo laptop, the status lights may not come up when you connect it to power. Another common cause of Lenovo not showing status lights is if you install new hardware like SSD or RAM in the laptop. This installation can affect the motherboard, and your laptop may not display status lights when you turn it on.
Also, an old, worn-out A/C adapter or charging port will not conduct voltage to the laptop. Meaning the laptop will get power; the power button may flash, but the status lights remain off. The same goes for a faulty A/C adapter. If the A/C Adapter is damaged, you can plug it into your laptop for hours, and you won’t see status lights because the charger isn’t supplying voltage to the laptop.
- Connect the laptop to a power outlet.
- Check the lower part of the display screen or near the A/C adapter hole for the indicator light.
- If it is not showing, plug an electrical appliance into the socket to confirm that the socket is working.
- If it’s not, plug the laptop into another power outlet.
The status lights should come up now. Otherwise, proceed to the next step to fix it.
Solution 1: Check The A/C Adapter Or Port
To check if the power cord of the Adapter is damaged;
- Plug the A/C Adapter into a power outlet and connect to your Lenovo laptop.
- If you see no status lights, check for faults or signs of damage on the Adapter or charging port. (Techies will know this best).
- If the two are in good condition, the fault is the power outlet.
- Confirm that the power outlet is functioning.
- If yes, proceed to the next steps to fix the issue.
Solution 2: Remove A/C Adapter And Battery
- Disconnect the laptop from the power outlet.
- Remove the external battery.
- Press-hold the power button for 30 seconds.
- Connect the laptop to power.
- Turn on the laptop.
If the status lights are still off, proceed to the next step.
Solution 3: Power On With Battery
- Unplug the laptop from the power source.
- Replace the external battery.
- Press-hold the power button for 30 seconds.
- Connect the Lenovo laptop to power and turn it on.
Solution 4: Use Novo Button
Some of Lenovo’s IdeaPad series like the IdeaPad 110 come with a NOVO button that resets the laptop into recovery BIOS if the device isn’t booting. The NOVO button comes with the OneKey Recovery software, backup important data before restoring the laptop to default. To troubleshoot no status lights using the NOVO button;
- Locate a curved arrow-shaped button on the side of the laptop or near the power button and press it.
- Select system recovery on the menu
- Boot the laptop.
Solution 5: Emergency Reset Hole
- Disconnect the laptop from the power.
- Remove the battery.
- At the back of the laptop, locate the emergency reset hole on the base plate
- Insert a pin or paperclip into the hole, and press-hold for 15 seconds.
- Plug the A/C Adapter and turn on the laptop.
Solution 6: Drain The Residual Power
Residual power is stored in the capacitor inside the laptop. It is the power left on the laptop after you’ve disconnected the A/C Adapter from a power source and can make the laptop misbehave while charging.
To drain residual power on the Lenovo laptop;
- Remove the bottom cover of the Lenovo laptop (the procedure varies for different models).
- Take out the external battery.
- Press the power button ten times. Press-hold the power button for 30 seconds on the eleventh time.
- Put the batteries back in.
- Connect the laptop to power and let it charge for a few minutes.
- Turn on the laptop and then shut it down.
- Replace the battery pack and turn on the laptop.
