ASUS Portable AiO PT2001 Troubleshooting
This troubleshooting page will guide you through common issues of the ASUS Portable AiO PT2001, and show you how to solve these issues.
PC’s battery not charging/not holding charge
The battery is not charging but the light may or may not be on.
Faulty power adapter
Make sure that the power adapter is plugged in to a power source and the charge light is on. If the computer is still not charging and the light is not on, then the power adapter could be at fault. Consider purchasing a new power adapter.
Faulty charging port
If the battery will not charge but it had been draining at normal rates before this problem occurred, then the charging port may be faulty. Open the back casing of the computer by removing the screws and inspect the charging port. Clean any debris from the port and ensure no connections are broken.
The computer will only operate while plugged into the power adapter, no matter how long you let it charge. These symptoms mean the battery is faulty and needs to be replaced. Replace the battery with this guide.
PC overheats when it is under load
The computer feels very hot to the touch after prolonged use.
Open up the back of the computer carefully while make sure not to make contact with any internal components. Then turn on the computer and open some power-intensive applications. Check whether the fan is spinning. If the fan spins properly, turn off the computer first and then clean the fan using compressed air. If the fan does not spin, check whether the power connection for the fan is loose. If the power is connected and the fan is still not spinning, consider replacing the fan.
Faulty heat sink
Carefully open up the back of the computer while taking care not to make contact with any internal components. Then turn on the computer and open some power-intensive applications. Inspect the heat sink and take temperatures of areas near the heat sink using a infrared thermometer. If the temperature is distributed very unevenly, the heat sink is faulty. Turn off the computer first. Ensure the heat sink is secured in place and makes proper contact with overheating components. If everything is in place, the problem might be caused by the thermal paste on the CPU. Remove the old paste and apply a new one in the center of the CPU. Then put the heat sink back. If overheating problem persists, consider replacing the heat sink.
PC’s audio is distorted
The audio coming out of the computer is difficult to listen to, or you can’t hear anything when you think you should be.
Mute Application Settings
Confirm that the PC's volume is turned on. If an application on the PC is mute, check its internal settings to ensure that the volume is turned on.
Faulty headphone jack
If you are listening to audio through your headphones, but the sound is distorted then the problem may lie with the headphone jack. To confirm that the jack is causing the issue, first open up the back of the device. Then check where the headphone jack is. The port may be loose or disconnected. If this is not the case, then you might want to considering replacing the jack entirely.
If you are listening to audio through the device and it either sounds distorted or you can’t hear it at all, then the speakers might be at fault. Make sure the speakers aren’t lose. If you can't diagnose a problem, consider replacing them altogether by following this guide.
PC’s files disappear
Files on the computer randomly disappear and PC’s file storage seems to act up.
Failing hard drive
The mechanical hard drive in the computer is designed to last for years, but since it has mechanical parts, it is susceptible to wear and tear. As the hard drive degrades, it will show symptoms such as clicking noises, frequent crashes and freezing, and corrupt data. If these occur, immediately back the hard drive’s data up to a different hard drive. Then replace the hard drive, which is described in the hard drive replacement guide.
Malware has the potential to wreak havoc on a system. Malicious software such as worms and spyware are created to steal information from users, which can result in missing files. Install an anti-malware software such as BitDefender, MalwareBytes, and SpyBot Search & Destroy. Then, perform a full system malware and virus scan, which may take minutes to hours.
PC runs unusually slow
Applications run slowly, the PC freezes, and/or the PC boots slowly.
Hard Drive is fragmented
The NTFS file system which Windows uses allows for file fragmentation, a phenomenon where portions of files get separated as data is deleted and rearranged. When this ‘fragmented’ file needs to be read, the hard drive head must physically move between different places on the hard drive, leading to slow performance. Defragmenting a hard drive optimizes it by reassembling fragmented files and grouping all of the empty space on the drive together. Defragmenting the drive can be done by searching for ‘Defragment & Optimize Drives’, selecting your hard drive (Usually ‘(C:)’), and clicking ‘Optimize’.
When programs and processes within Windows are running, the computer’s processor uses RAM to store data about those applications in memory. If there are too many programs running, the processor will use up all of the RAM and start writing data to the hard drive, which is much slower than RAM. The amount of RAM used can be monitored by opening Task Manager, clicking the ‘Performance’ tab, and clicking ‘Memory’. If the RAM used is at 90-100% at your preferred workload, then the RAM should be upgraded, as is described in theRAM replacement guide.
Malware, in addition to potentially stealing information and causing harm to the computer and the user, places an increased load on the CPU, RAM, and hard drive. Install an anti-malware software such as BitDefender, MalwareBytes, and SpyBot Search & Destroy. Then, perform a full system malware and virus scan, which may take minutes to hours.
