I'm trying to resurrect a Toshiba Libretto 100ct which I purchased cheap at a hamfest allegedly as "working". :roll: Current configuration is as follows:
- P-166MMX CPU
- 64mb RAM (optional 32mb module installed)
- no hard drive (bracket was not included so I can't stick one in for troubleshooting)
No accessories were included; I just purchased the AC adapter to begin troubleshooting.
Here's where I stand:
- When I plug it in, the DC in and batt charge LEDs are lit.
- When I power it on, the power LED also lights and the speakers initialize, but that's all I get... on the sixteenth keystroke (or after holding a key long enough) it gives a system beep per keystroke. Pressing the power button again gives a short higher-pitched beep and power-off is normal. The LCD does not initialize at any point.
- When I hold ESC and power-on (to enter BIOS), I get the same results with no display.
- However, when I hold F12 and power-on (to enter BIOS flash update mode), the LCD initializes/lights fully and displays the text message for that mode with no problem (no dead pixels, woohoo
)! Thus the LCD is not the issue and there is obviously some measure of functional logic on the motherboard. I have not yet tried flashing the BIOS since I don't have the floppy drive yet.
- All behavior is the same whether the battery is installed or not.
I've checked the service manual and the relevant Toshiba Support article already... here are my current questions:
- Farfetched as it seems, does a Libretto with no disk installed fail to display anything at power-on? UPDATE: THE ANSWER IS YES! For shits n giggles I threw in a 2.5in disk with no bracket, and the system gave a POST beep, followed by an F1 prompt to enter BIOS due to cleared CMOS! Hooray!:beer::thumbsup:
