[QUOTE="pcrepair, post: 2417, member: 1"] It sounds like your HP Pavilion laptop is experiencing a hardware issue that prevents it from starting up fully. Since you've already replaced the battery, the problem might lie elsewhere in the power delivery or internal components. Here's a step-by-step guide to troubleshoot the issue before deciding whether to replace the laptop or take it to a professional: 1. Perform a Hard Reset Disconnect the charger and remove the battery (if removable). Hold down the power button for 30-60 seconds to drain residual power. Reconnect only the charger (leave the battery out) and try turning it on. 2. Inspect the Charger and Power Port Ensure the charger is working by testing it with another compatible device or using a multimeter to check the voltage output. Inspect the charging port on the laptop for any damage or debris that might prevent proper power delivery. 3. Test Without Peripherals Disconnect all peripherals (USB devices, external monitors, etc.) and try powering on the laptop. A faulty peripheral or connected device could cause startup issues. 4. Check for Power Delivery Issues If the power light comes on briefly but the fans and hard drive don’t start, the issue might be with: The power button or its connection. The motherboard's power circuit. The DC jack or power adapter board (if separate from the motherboard). 5. Inspect the Internal Components If you're comfortable disassembling the laptop: Open the laptop and check for visible signs of damage (e.g., burnt components, swollen capacitors, or loose connections). Reseat the RAM, SSD/HDD, and any removable internal components. Look for loose or disconnected cables, especially the ones connecting the power button and battery. 6. Reset CMOS If accessible, remove the CMOS battery for a few minutes to reset the BIOS. Replace it and try powering on the laptop again. 7. Check for Motherboard Issues If none of the above steps work, the motherboard or a related component (e.g., voltage regulator, GPU, or CPU) might be faulty. This typically requires professional diagnosis and repair. When to Replace the Laptop If the cost of professional repair or replacing major components like the motherboard exceeds the laptop’s value, it might be more practical to replace it. However, if the laptop is relatively new or valuable, repair could be worth it. [/QUOTE]
