Gaming laptops can suffer from a wide range of power-related faults, and a laptop that appears completely dead does not always mean the motherboard has failed. This Asus G513R gaming laptop came into us with a no power fault, and the customer was unable to get the machine working.
At AC Computer Warehouse in Stockport, we repair and diagnose gaming laptops including Asus ROG, Asus TUF, MSI, Alienware, Lenovo Legion, HP Omen, Acer Predator and other high-performance laptops. This repair is a good example of why proper diagnosis is important before assuming the worst.
The Fault: Asus G513R Gaming Laptop With No Power
When this Asus G513R arrived, it was showing no normal signs of powering on. With no power faults, there are several possible causes, including:
- Faulty charger
- Damaged charging port
- Battery fault
- Motherboard issue
- Shorted component
- RAM fault
- Loose internal connection
- BIOS or power rail problem
Because gaming laptops are more complex than standard laptops, guessing the fault is never the right approach. The first step was to strip the laptop down and carry out proper checks.
Stripping Down the Asus G513R
The laptop was stripped down so we could inspect the internal components, battery, motherboard, cooling system, RAM slots and power input area.
Gaming laptops usually have larger cooling systems, dedicated graphics hardware, larger batteries and a more tightly packed internal layout. This makes proper inspection important, especially when dealing with no power faults.
Once opened, the internal layout of the Asus G513R could be checked properly. During the inspection, the issue became clear: one of the RAM modules was not seated correctly.

The laptop was stripped down to inspect the motherboard, cooling system, battery and RAM area.
The Cause: RAM Module Half In and Half Out of the Slot
After inspecting the inside of the laptop, we found that the RAM module was sitting half in and half out of the RAM slot. This can stop a laptop from booting properly and may cause the machine to appear completely dead or fail to start.
RAM needs to be seated firmly and evenly in the slot. If it is loose, angled or not clipped in properly, the laptop may fail its startup checks and refuse to power on correctly.
A badly seated RAM module can cause symptoms such as:
- No power
- No display
- Laptop turning on briefly then shutting off
- Keyboard lights appearing but no boot
- Fans spinning but no image
- Random freezing
- Memory errors
- Intermittent startup problems
In this case, the RAM module was not correctly installed in the slot, which was preventing the laptop from starting normally.
Testing the Charger and Voltage
As part of the diagnosis, we also checked that the laptop was receiving power correctly from the charger. The voltage reading showed around 19.86V DC, confirming that the charger input voltage was present.
This helped rule out the charger as the main cause of the no power fault and confirmed that the issue was internal rather than simply a failed power adapter.

Voltage testing confirmed that the laptop was receiving the correct charger voltage.
Reseating the RAM Module
Once the RAM issue was identified, the module was removed and correctly reseated into the RAM slot. The RAM was fitted firmly and evenly, making sure it locked into place properly.
This is a simple-sounding fix, but it is exactly why proper diagnostics are important. A laptop with no power can sometimes be misdiagnosed as a motherboard failure, when the real issue is a loose or incorrectly seated internal component.
After reseating the RAM, the laptop was tested again.
Successful Power On Test
After the RAM module was correctly seated, the Asus G513R powered on successfully and displayed the Republic of Gamers boot screen.
This confirmed that the no power issue had been caused by the RAM not being seated correctly, rather than a failed motherboard, faulty DC jack or charger fault.

After the RAM module was correctly seated, the Asus G513R powered on successfully.
Why Proper Diagnosis Matters With Gaming Laptop Repairs
A gaming laptop with no power can look like a serious fault, but the cause is not always obvious from the outside. Without stripping the machine down and testing properly, it would be easy to assume the laptop needed expensive motherboard repair.
Proper diagnosis helps identify whether the fault is caused by:
- Charger or adapter issue
- Battery problem
- Charging port fault
- Loose RAM
- Failed RAM module
- Internal connector issue
- Motherboard short
- Power rail fault
- Liquid damage
- BIOS problem
In this case, the repair was much simpler than it first appeared. The RAM module was not seated correctly, and once this was corrected, the laptop powered on again.
