Quando no meu navegador percorrer uma página da web, ele congela em intervalos de 4 segundos, não por muito tempo, mas é um aborrecimento. Isso também acontece quando eu faço streaming de vídeos, embora o som não seja afetado (primeiro, achei que era apenas o vídeo que era o problema - então percebi que isso acontecia durante a navegação)

aspm: PCIe ASPM test.
--------------------------------------------------------------------------------
Test 1 of 2: PCIe ASPM ACPI test.
FADT X_FIRMWARE_CTRL 64 bit pointer was zero, falling back to using
FIRMWARE_CTRL 32 bit pointer.
PCIe ASPM is controlled by Linux kernel.
Test 2 of 2: PCIe ASPM registers test.
WARNING: Test 2, RP 00h:01h.00h L0s not enabled.
WARNING: Test 2, Device 01h:00h.00h L0s not enabled.
ADVICE: The ASPM L0s low power Link state is optimized for short entry and exit
latencies, while providing substantial power savings. Disabling L0s of a PCIe
device may increases power consumption, and will impact the battery life of a
mobile system.
PASSED: Test 2, PCIe ASPM setting matched was matched.
WARNING: Test 2, RP 00h:1Ch.01h L0s not enabled.
WARNING: Test 2, RP 00h:1Ch.01h L1 not enabled.
WARNING: Test 2, Device 03h:00h.00h L1 not enabled.
ADVICE: The ASPM L0s low power Link state is optimized for short entry and exit
latencies, while providing substantial power savings. Disabling L0s of a PCIe
device may increases power consumption, and will impact the battery life of a
mobile system.
ADVICE: The ASPM L1 low power Link state is optimized for maximum power savings
with longer entry and exit latencies. Disabling L1 of a PCIe device may
increases power consumption, and will impact the battery life of a mobile system
significantly.
FAILED [MEDIUM] PCIEASPM_Unmatched: Test 2, PCIe ASPM setting was not matched.
RP 00h:1Ch.01h has ASPM = 00h.
Device 03h:00h.00h has ASPM = 01h.
ADVICE: ASPM control registers between root port and device must match in order
for ASPM to be active. Unmatched configuration indicates software did not
configure ASPM correctly and the system is not saving power at its full
potential.
WARNING: Test 2, RP 00h:1Ch.02h L0s not enabled.
WARNING: Test 2, Device 04h:00h.00h L0s not enabled.
ADVICE: The ASPM L0s low power Link state is optimized for short entry and exit
latencies, while providing substantial power savings. Disabling L0s of a PCIe
device may increases power consumption, and will impact the battery life of a
mobile system.
