Common laptop symptoms, their usual causes, the LaptopHaber repair and typical price
| Symptom | What it usually is | Our repair | Typical price |
| Will not power on at all | Usually a blown fuse, shorted capacitor or failed charging IC — very rarely a dead board | Rail tracing on a bench DC supply, component replacement | £99 – £249 |
| Powers on, screen stays black | Failed backlight circuit, loose or chafed display cable, or a dead GPU solder joint | External display test, cable or panel swap, GPU reflow / reball | £89 – £279 |
| Runs hot, fans roar, then shuts down | Thermal paste has dried out and the heatsink fins are matted with dust | Full strip, fin clean, fan replacement, premium re-paste | £69 – £119 |
| Battery drains in minutes or will not charge | Cell degradation past 500 cycles, or a failed charging circuit on the board | Battery health report, then cell or charging-IC replacement | £69 – £159 |
| Trackpad rising, chassis bowing | Swollen lithium-ion battery — a genuine fire risk, stop using the machine | Immediate safe removal, disposal, replacement cell | £89 – £179 |
| Everything is slow, especially start-up | Mechanical hard drive, full or failing SSD, or a thermally throttled CPU | SMART check, NVMe migration with full clone, thermal service | £79 – £159 |
| Random blue screens or freezes | Failing RAM, a dying drive, or a driver conflict — three very different bills | MemTest86 overnight, SMART analysis, clean driver stack | £49 – £169 |
| Lid cracking away from the base | Hinge mount has torn out of the plastic; every open and close makes it worse | Hinge mount rebuild and re-bond, or chassis replacement | £89 – £199 |
