HP Pavilion D7 1448DX
Tried changing HD but now find laptop starts, then quits. Here are some of the things observed...
  • Will not start w/battery alone or w/cord alone but only w/cord & battery inserted.
  • W/cord & battery the startup only last for about 2 secs.
  • No lights w/cord only or battery only.
  • Lights only the flashing 'Lighting bolt', w/other lights grayed out and pulsating.
  • Had USB bootable attached during the first attempt at startup, then in and out during other attempts.
Most usual, as the laptop, showed no problems before HD exchanged. Have reset RAM, removed/reinstalled the CMOS battery, reinstalled old HD, held power button down before/during CMOS battery removal and RAM and check on possible dust clogs and CPU temp. No avail.

Don't have another battery or tester nor electric 'sniffer' to test cord.

Any ideas?
