Slow Laptop After SSD Upgrade: Charger Likely the Culprit
A two-year-old HP ac115ns with a dead hard drive and failing battery. The owner did what anyone would: replaced the HDD with a Kingston A400 480 GB SSD, installed Windows 10 from scratch, and waited for the instant boot promised in ads. It never came. Chrome crawls, basic tasks take forever, and the battery dies before drivers finish installing. The laptop ended up at a repair shop before home diagnosis was possible.
The case, detailed on a consumer forum, is a mini-treatise on remote computer diagnostics. And how instinct—blaming the OS, new disk, or bicho—often points to the wrong place.
Why an SSD Doesn't Always Fix Slowness
The owner's logic was sound: if the bottleneck was the mechanical drive, an SSD would eliminate it. But the system remains slow with fresh Chrome and minimal programs. The user reveals a key detail: the old drive ran Total War Rome 2 at high graphics. Hardware wasn't the issue.
Here begins the trail. An SSD rated for 550 MB/s showed unstable peaks of 7, 250, and 700 MB/s. This inconsistency isn't normal and suggests deeper problems than the disk itself.
The Non-Charging Adapter: The Overlooked Clue
The critical symptom appears late: the laptop doesn't detect the charger when powered on, relying solely on battery. It charges only when off. Without battery, it won't start. This combination—weak adapter, dying battery—explains the sluggishness and inability to install drivers.
The most reasonable hypothesis is a faulty charger delivering insufficient power. A universal adapter costs under 20 euros, so confirmation would be good news. Alternatives like motherboard or BIOS errors are more serious.
Windows 10 Drivers: Do They Install Automatically?
Another question: does Windows 10 install drivers by default? Practically, Windows covers basics, but manufacturers offer specific drivers—graphics, chipset, power management—that should be installed from their websites. On a machine with AMD Radeon R5 340 and Intel Core i3 5005U, these make real performance differences.
Some recommend checking BIOS disk mode (AHCI vs RAID), a setting that can hinder SSD estimulante ilegal if misconfigured from factory.
Clean, Check, and Distrust First Diagnoses
Common advice includes thermal paste replacement and fan cleaning. Dry thermal paste raises temperatures, causing CPU throttling. Screenshots show the processor running at 490 MHz, far below its nominal 2 GHz. This alone explains much of the slowness.
Booting from a Linux USB stick is suggested to distinguish software from hardware issues—a simple test the owner skipped before visiting the repair shop.
The Repair Shop Has the Final Word
The laptop is with a technician who confirmed the SSD works correctly. Diagnosis continues: charger, battery, board, or BIOS. The owner promises updates once resolved.
Meanwhile, lessons accumulate: an SSD doesn't revive a laptop if power, cooling, or firmware configuration fails. The overlooked charger might be why everything else seems broken.
