Question about HP OmniBook 6000 Notebook
I upgraded an HP Omnibook 6000 with additional memory, new battery, Windows XP (from 98) and it has been running perfectly for about 2 weeks. A diagnostic run before installing XP showed some bad sectors on the disk, but otherwise fine.
A few days ago the silent boot mode changed of its own accord and demanded a battery test.There also seemed to be random key strokes causing the start menu to keep appearing without pressing any keys and the BIOS setup was also cycling through options on its own. I reset the BIOS to factory settings and it booted normally and the random keystrokes stopped.
I ran diagnostics again. This time there were 2 disk test failures (which I can't remember or access the log any more). Installed a new disk. This draws more power than the old one (1A rather than 500ma) but it seemed to work fine. However the random keystrokes came back.
Now it fails to run POST, and 3 of the front panel LEDs are permanently illuminated, including the second battery light showing red even though there is no battery present. Removed the battery, re-inserted and the LEDs come on. Removed battery, plugged in AC and the lights come on, but different depending on whether battery or AC connected and if the removeable CD drive is present.
CPU running LED is orange except when CD drive is present and AC connected when it shows green.
Battery1 LED is orange when CD drive present and green when absent on both battery and AC.
Battery2 LED is orange on battery and red with AC connected.
I suspected the CMOS battery, but this measures 3v and shows no sign of corrosion in the socket.
Any ideas on what needs replacing ?
When was the last time a BIOS update was done? See if one is available for this laptop and give it a try. FOLLOW THE INSTRUCTIONS TO THE LETTER WHEN DOING THIS OR YOU CAN RENDER THE LAPTOP INOPERABLE!! If youre not comfortable doing this, have a service technician do it for you. Sounds like the problems really went into overdrive when the new drive was installed.
