Computer plugged in but not charging

Computer plugged in but slowly draining battery.

Broken cable/adapter

Scan over the cable/adapter and check if anything seems out of place or broken. There may be kinks or cuts in the cable. Make sure that the cable is firmly inserted in the adapter block. If your cable and adapter look intact, your BIOS may need to be reset.

Error in BIOS settings

Ensure that your computer is unplugged from any power source. Start up the computer and when you see Lenovo appear on your screen, press F1 repeatedly until you are redirected to a setting screen. If you press the F1 button too late, your computer will start as normal and you will not be redirected to the settings page and you will have the restart the computer and try again. Next, navigate to the Config tab using the arrow keys, if you are confused about how to navigate through the settings, there are directions at the bottom of the screen. Select Power by hitting enter. Next, select ‘Disable Built in Battery,’ which will power down the computer. Wait 30 seconds, then plug in the power cable and restart the laptop. If this does not power back on, you can reset the BIOS manually.

First unplug the adapter from the computer and completely shut the computer down (hold the power button for 10 seconds). Use a paperclip, toothpick or another small object and insert it into the small hole found on the underside of the computer, near central air vent. You should feel a small click to ensure the Reset button has been pressed all the way. After you remove the small object of choice, plug the adapter back in to the computer and power on as usual. If this doesn’t work, your battery may need to be replaced.

Bad battery

Please read our battery replacement guide.

Computer is overheating

Computer feels really hot and the fan is loud and running at excessive speed.

BIOS out of date

Refer to this video on how to update your BIOS system.

Dirty cooling fan

Refer to this guide on how to clean or replace your fan.

Computer is running slow

Computer is not loading or processing in a timely manner

Computer is lagging

If you are experiencing problems with your computer loading really slow or lagging, you may need to reboot your computer. This will likely fix your problem if your computer has not been rebooted recently. If rebooting your computer does not fix your problem, you may have too many programs running in the background.

Too many background programs

One of the most common reasons for a computer running slow is too many programs running in the background. Remove and disable necessary background programs that automatically run each time the computer restarts. If you have an antivirus scanner, spyware protection program, or another security scanning utility, make sure it is not scanning in the background. If one of these programs is scanning, it will decrease the performance of the computer. If one of these programs is scanning, allow the scan to be complete and the computer’s performance should improve. If closing these background programs does not work, you may have too many temporary files stored on your hard drive.

Too many temporary files stored on your hard drive

As a computer runs programs, temporary files are stored on the hard drive and having too many of these temporary files may slow down the performance of your computer. First, attempt t use the Windows Disk Cleanup utility to delete temporary or unneeded files from your computer. While the Disk Cleanup file will delete many of the temporary files, it may not delete all of them. Next, you may need to delete your temporary files manually. To do this, open the Start menu and type %temp% in the Search field. In Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field. Press Enter and a Temp folder should open. You can delete the files in this folder and if any of the files are in use and cannot be deleted, the can be skipped. If this does not work, you may need to examine your hard drive.

Full or faulty hard drive

Open up the settings on your computer and verify that there is at least 200-500 MB of free hard drive space. This space allows the computer to have room for the swap file to increase in size, as well as room for temporary files.

If the space is not an issue, you may have a bad, corrupted of fragmented hard drive. Run a ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with your hard drive. Also run Defrag to help ensure that data is arranged in the best order possible. If none of this solves the problem, your computer may have a virus.

Computer has a virus

If your computer is infected with any viruses, this may cause it to run much slower. If you do not have an anti-virus program installed, you can run Tend Micro’s free Housecall online utility scan for viruses on your computer. This program will help identify any viruses on your computer and remove them. It is recommended that you install an antivirus program. If a virus is not the problem, you may need to screen for spyware or malware.

Computer has spyware or malware

Spyware and malware can also cause your computer to run much slower than normal. Even if there is an antivirus program installed on your computer, it is recommended to run a malware scan as well. Use the free version of Malwarebytes to scan your computer. If your problem is not attributed to malware, there may be a hardware conflict.

Hardware conflicts

Verify that the Device Manager has no conflicts. If any exist, resolve these issues as they could be the cause of your problem. If this is not the problem, you may need to update your computer.

Computer or drivers outdated

First make sure you have all of the latest Windows updates installed. If you are on the Internet while your computer is being slow, make sure all of the browser plugins are up to date.

It is also possible that your drivers may need to be updated. Make sure you have the latest drivers for your computer hardware, especially the latest video drivers. Slow performance could be caused by having out of date drivers. After you have made all of the above changes, reboot your computer again and recheck the performance. If none of this solves your problem, you may need a memory upgrade.

Memory out of date

If you have had your computer for 2+ years, you may need more memory. Having enough memory will allow your computer to not have to swap information stored in the memory to the swap file. If the hard drive light is constantly active, it can indicate that the computer is frequently swapping information between your memory and your hard drive.

Run out of storage space

There is not enough storage on your computer.

Too many programs installed that are not being used

Open the File Explorer and select This PC on the left side. Then click the Computer tab located on the top left. You should see an option of Uninstall or change a program. Click on that and you will see all the programs that you have installed on your laptop. Click on the name of the program that you no longer need and select uninstall. Follow the instruction to finish uninstall. If this does not work, there may be too many temporary files stored in your hard drive.

Turn your computer on and when the Lenovo screen appears, press the F1 key multiple times until you are redirected. If you hit the F1 key too late, your computer will power on as usual and you will not be redirected into BIOS. If this happens, restart your computer and try again. Once you are redirected into BIOS, a message should appear that says ‘Entering System Setup’ which signifies you are in BIOS. If you are unable to get into BIOS, try pressing the blue ThinkVantage button or press the Enter key.

Once you are in BIOS, open up the operating system. Click start, point to All Programs, point to Accessories, then click Notepad. Using the internal keyboard, press each letter key and each number key to determine if the keystrokes are being recorded properly. If certain keys do not work, make note of these. Check to see if any keyboard mapping software has been installed that may with your normal keyboard functions. Boost into Windows Safe Mode and retest your keyboards functionality.

Un commentaire

On the “Computer plugged in but not charging”, you might consider adding the possibility that the power jack inside the laptop is damaged. This might be the case if the “charging/Power” LED goes on/off as the power cord is moved around while plugged in. That is the problem I developed today on a Thinkpad X1 Yoga (1st gen) and I’m trying to figure out if the internal connector can be replaced or repaired. Pretty certain the M/B needs to be removed to have any chance but that is as far as I’ve gotten.
