Why Revitalize an old laptop
•
•
•
•
My proposal
I inherited this laptop
Cost me nothing
We can stay in touch
while traveling
• I always wanted a
laptop
• Great project to
revitalize the machine
• Wife’s comments
• Don’t bring home
junk
• Obsolete and useless
• Waste of time and
money
• Smells of mildew and
fungus
• Get rid of it!
She is right of course but…
it has a soul that needs to be saved

Testing
•
•
•
•
•
•
Unplugged? No response. Batteries dead
Plugged in. Green power light on. Turned on.
Passed smoke test but….
Boot failure: Battery CMOS checksum errors
Pressed F1 for Setup, End to save and yes.
Successful boot and Windows 95 Startup
It works!
Revitalization
• The soul of the old
machine revitalized by
electrical jolt
• Major functions
seemed normal but….
• “What kind of monster
have I created”
thought Dr.
Frankenstein?
Further Testing: Software
• Windows 95 seemed to work as well as ever
• Clock reset manually as CMOS battery was dead
• Word and Excel handled test documents and
spreadsheets normally
• Outlook Express was reset for my account and
checked email. PCMCIA model worked
• Internet Explorer worked but dial up is so slow
• Downloaded and installed PowerPoint 97 Viewer
• MS Schedule removed from Start folder
• Personalized: Names, log on etc. changed
Further Testing: Hardware

All three battery packs dead. Zero volts $$$
Screen dim and hard to read in some light
External monitor worked well to 1024x780
Accupoint worked but flakey. External mouse OK
PC Card 28.8 modem worked but slowly with
Telus dial up (I have 15 hours a month available)
Conclusion: It is a keeper!
A functioning machine that satisfies my basic
Must objectives and has some limited potential
