Symptoms:
- Laptop Sony sve171a11m boots as normal to bios screen.. it sometimes advances to windows booting screen(dancing circle) or not. It shuts it self off, as in instant power stoppage.
Proposed solutions:
- Laptop power regulator failure? : No. Mainboard replaced(costed me $180) but same symptoms
- Hard drive(software corruption)? : No. Detached hard to boot: well.. it said no bootable device. and shuts off..
Parts(as i see)- Hard drive(software corruption)? : No. Detached hard to boot: well.. it said no bootable device. and shuts off..
