Lenovo is known to be a go-to brand when it comes to building reliable and well-priced laptops. They seem to have pretty much every segment of the market covered with their laptops. Sometimes you can come across a myriad of issues. Some complex others being simple. This tutorial will show you how to resolve random shutdown issues on your Lenovo laptop.
1. Inspect if the AC adapter’s output plug as well as the input port on the laptop are not damaged. If the AC adapter’s input plug is damaged, replace the adapter and see if the issue persists.
2. If the issue persists, remove the battery and try powering up the laptop and take heed if it shuts down while on AC power.
3. If the issue persists, with the battery populated and the AC adapter disconnected, see if the laptop powers up and does not undergo a random shutdown.
4. If the issue persists, disconnect from the AC power adapter, remove the laptop battery and press and hold down the power button for at least 30 seconds.
5. Replace battery and try to power up and inspect for any signs of random shutdown while on battery or AC adapter power.
6. If the issue persists, while your laptop is powered down, look for the SKU for your laptop. It should be contained on a sticker near the battery/service plate cover.
7. Visit Lenovo’s support site with respect to your laptop’s SKU and see if you have any BIOS updates pending. At this point you should also check to see if all your drivers (namely chipset and management engine interface, if Intel) are up to date.
8. If you’re working on Microsoft’s Windows OS environment, see if changing the power settings from Balanced to High Performance changes the issue. Right click start>Power options>Settings>System>Power & Sleep (on the left pane)> Additional power settings>High performance.
9. If that doesn’t change it, you can control the level at which your processor operates. You can go into Change advanced power settings in Step 3. Under Processor power management, look for Maximum processor state. Set the maximum processor state to a lower number and see if that changes the issue.
10. If the issue persists, backup your critical files and folders and reinstall your OS after you’ve recreated the bootable installer to rule out a corrupt installer.
11. If you’ve performed a recent ram upgrade, try with only one stick of ram. If you’re mixing and matching the rams, remove the stick of ram that was newly introduced. If the issue is resolved, you will need to work with a ram kit that conforms to your ram slot and maximum capacity and frequency limitations. We’re also assuming you’ve performed a BIOS upgrade prior to the ram upgrade.
12. If you hear a click just prior to when the laptop shuts down, it’s possible that the HDD is failing. You can try and use a donor/replacement HDD to test out the theory.
13. Use a temperature monitoring app like HWMonitor or HWiNFO or Speefan or Realtemp and see what your temps are. You should be in the mid 30°C’s (depending on your room’s ambient air temps) at idle after booting into GUI.
14. If you can or can’t hear the fan spinning but the laptop is gradually heating up after booting into GUI, then your cooling solution is failing.
15. You will need to disassemble the laptop and inspect the fan and the cooling fins stack if there have been clogged with dirt/debris and/or hair follicles. If they are indeed clogged use a small soft bristled painters brush to dislodge the debris from the fins stack and the fan.
16. If the cooling assembly is clean and the fan doesn’t move, then the fan has given up the ghost. You will need to replace it with a similar/matching replacement part from Ebay or Aliexpress.
17. While mounting the cooling assembly back on, you will need to replace the thermal paste after removing the previously (factory) applied thermal paste with isopropyl alcohol. You can use nail polish remover in place of rubbing alcohol. You can use Arctic Silver 5 or Arctic’s MX-4 thermal paste.[/b]
18. If all the above doesn’t provide any fruition, it’s highly possible that the issue can be due to a fault/failing motherboard. There are a number of sources stating that some older models as well brand new to market models have experienced hardware failure. If the laptop is brand new then it’s worth sending it back via the RMA process.
from here.We have determined that an internal noise issue with the voltage regulation component is the common element. This is an electrical noise issue which manifests in a fairly small portion of the use base and does not appear to develop over time.
If the laptop isn’t brand new and outside the warranty period, you could send it into a certified laptop repair shop and see if the power delivery system on the board is crippled or if the board needs replacement.
Hopefully with you coming to the end of this tutorial, you will have solved the issue plaguing your Lenovo laptop with random shutdowns.
