Rehabilitating Damaged Laptops
Rollie Hawk writes "It breaks my heart to see a computer in need of a good home. For years, I've driven my wife crazy with all the 'strays' I've brought home with me. After all, the last thing my house needs is a few more cubic feet devoted to kenneling old and abused computers. That being said, laptops present very unique opportunities. No matter what caused you or someone else to ditch that old laptop, there still may be some way to integrate it back into society. For every kind of laptop lemon, I've found that there's plenty of lemonade to be made."
Another great use for laptops that are underpowered are as dumb wireless terminals. We have 10 laptops on our site (a public school) which we connect into a terminal server wirelessly and has given new life to laptops which would have just been thrown away.
I found a great use for an old discarded 486 laptop running DOS. It is now dedicated to writing C64 disks thanks to my X1541 cable :-)
In my case a friend ditched one since it had a broken keyboard. I got it for free simple fix I just got one of those flexable mini keyboards it fits perfectly over the old keylayout. so I can use it without having to lug around a full size keyboard and have it hanging all over the place taking up space. plus its rollable to It doesnt take up a boatload of space in my laptop case.
One of my pet projects now is to turn a laptop, a cuecat and a webcam into a fridge computer that will allow me to inventory my refridgerator as well as take a snapshot whenever I open the door.
Imagine using a WAP-enabled phone to check what I have in the fridge at home. No more "do I have milk?".

"If your old laptop has a tiny hard drive, and by small I mean under 100 MB of space, you may or may not be able to upgrade it. Even if you can, you are certainly looking at no more than a gigabyte of space and will probably be making use of someone else's used drive."
I could see using Windows...Hell, I used Win95 0SR2 on a 166mhz ATT Globalyst without much of a hitch.....Slow for mp3s, but ran most of the web and IRC chat well enough for me.
But Windows aside, he never makes mention of distros like Knoppix or even Damn Small Linux (Isn't DSL like 50mb?)...You could easily run a distro off a Knoppix or Live CD....Wouldn't it be more useful to do this, as one gets a full-fledged OS with software to boot?

My MythTV HowTo
I did just this when my 18 month old Toshiba Satellite Pro 3000 partially died making it useless for its primary purpose because the LCD backlight failed. I had only just replaced the battery because that had died and the case was made from a brittle plastic that left it prone to cracks and chipping. Basically, Toshiba isn't getting any more of my money, I bought an iBook G4 instead and it is coming up to 12 months old now and is in perfect condition despite the daily use that wrecked the Toshiba in a similar amount of time.
Anyway, the Tosh does have a few redeeming features, it has built in 10/100 ethernet fully supported under Linux, 1Ghz PIII CPU and a 20GB disc. With a new battery and no backlight it will run for over four hours without power so it made sense to make it a server. Currently it has an HP laserjet 1200 hanging off it, served with Samba to support printing from Windows, Linux and OS X, it has network shares (Samba and NFS), DNS (using dnsmasq, much easier to set up than bind), DHCP, squid web proxy (including wpad.dat configuration for automatic detection by IE and Firefox), IMAPS for serving e-mail with fetchmail to pull it down from my pop accounts, Openwebmail to allow me to send and receive mail from anywhere in the world using ipcheck to update my dyndns records so I don't have to remember my specific IP address, spamassassin to filter all the crap about viagra etc, and clamwin antivirus before mail ever hits a Windows box (yeah yeah, I shouldn't use Windows for e-mail and browsing, but I have thunderbird and firefox as defaults and I only really use Windows for games but it is still nice to feel I can read mail and browse a little with some level of safety).
Actually, now I feel less bothered about the £1500 the laptop cost me because with all it is now doing as a server I feel like I can get several more years use out of it. Although, compared with the £1000 the iBook cost I still think Toshiba blows.
In the end, setting up this machine as a server has been great experience, I have got it interacting with my heterogenous environment and it does a lot for such a little machine. Oh, and the lack of fan noise and small size is also a real bonus.

About 2 years ago I found in one of the closets at work an old VAIO PIII 600Mgz. /syspart:D /tempdrive:D to install a disk that is than removed and put in another machine. Just do winnt32 /? to read all about it).
I ask around and the boss said it is broken and Sony labs ask for more then a new VAIO to fix it. So I took it home. I work on it at nights before going to sleep.
The case was all broken and the keyboard popped out. When plugged into the power the light goes on but nothing happens. So I opened it up. I saw the CPU fan was dismantled, probably when it was dropped and the case broke. I changed the fun and connected it. Now the fan turns but still nothing happens. I played around with it for days (nights) by chance I changed the alternate-BIOS dipswitch and the screen comes to life. What? The BIOS was over-written how did that happen? I scraped up from the net some source code for a little program that I ran on a friend VAIO, to copy his BIOS, then to write the one on my machine. OK now I'm at the boot prompt. I see the HD is dead. I order 40g one from compgeeks.com. Mean while I take it all apart, glue up the case real nice. 80% of the screws where missing, so I go downtown to find some. The battery mechanism is broken. Ha, I fix it in place with Masking tape. The HD arrives. Now the VAIO has neither floppy nor CD. Easy, put the HD (with that 2.5 HD kit) in a desktop machine. Hatch a windows XP installation. (Hatch is when you do> winnt32
That's it the VAIO is working. And it is so nice it is half the weight from my wife's 700Mg Celeron Thinkpad. Feels faster and lasts x3 on a full battery.
Well not so good, my boss comes one day and ask where is that old laptop. I tell him I have it. He says he wants it back. Now, there is no way I'm going to give it back after all the work I put into it. We have a big fight about it. Finally he admits that he needs the power-supply so he can have one at home and one at work so he doesn't have to carry the power supply three meters to the elevator and back. I Juice up the VAIO for the last time. And bring him the PWSP.
It is sitting there with power for one go. It took me 14 month and I'm at a dead end. A new PWSP is $200 and it has to be specially ordered since they don't carry them any more. Well 2 month ago, I go to NY (a sad occasion I'm afraid) and I find on 14th st an Original VAIO PWSP for $40 . I now have Mandrake on my VAIO and I'm excited every time I use it. We have a special bond we're war-bodies. The only thing short of perfect is three keys missing on the keyboard: VBN. I can still press that little nipple below the key. One day I will carve these keys from wood.

not only obvious but extremely shallow.
"if it has a vga port you can use a capture card to put it on the tv."
HUH??
and he goes on talking about extremely basic things.
How about actually rebuilding the laptops? I've snagged dead laptops by the palletfull before and simply take them apart and replace cracked screens with working screens (need a number of the same model, easy to get from corperate auctions)
upgrading the hard drive can usualy be done, flashing the bios is the first step and there is still copies of the dreaded drive management software out there to force a large drive to work on a old machine.
Finally, the best thing is to put in a CF card caddy in the hard drive slot and add a CF card as the drive for unitask laptops. I did this with about 10 of them and set them up for the local ham radio group. write protect the CF card (if it has that switch) and use it as an appliance. works great for their packet radio, turn it on and it boots into their software.
Finally upgrades are possible. the Dell Lattitude Cpi's were very modular for almost 2 years of manufacturing. I upgraded my daughter's laptop from a P-II 266 to a P-II 400 by simply moving the procerssor module from the dead laptop to her's.
Personally, the only good old laptop to hold onto is the tandy 100 and any of the early toughbooks.
Do not look at laser with remaining good eye.
That's interesting. What kind of computations are you running there? The whole setup sounds like bloody heterogeneous (probably you have all different network, CPU speeds, memory sizes). My feeling is that besides for some pretty coarse-grained parallel jobs it is not good for anything else.
About 5 years ago I sold an old 68030 based Macintosh Powerbook on ebay. Before I did, I cleaned up the hard drive etc...
When I tested it, I was shocked. From OFF, not sleep, from off, it would boot and lauch Microsoft Word in 7 seconds.
Now that is impressive performance.
It was running MacOS 7.6.1 and Word 5.1. Both from the good old lean days.
We have certainly lost something since then.
I work at a library, where we have fairly comprehensive tech support availible to students. One thing we see a lot of is dead floppy disks. Over the summer, a student came to me with a dead disk containing his thesis. I put it in my laptop, a PI 166 running Slackware (Which is now damaged, and will be rehabilitated, because I love that thing, but that's not the point of the story!) and got most of his document back.
At the end of the summer, that student (I'll call him Mel, because that was his name*) gave an old 486-based Toshiba to my boss for some reason. So we were like, "You know...this thing is running Windows 95. The Win95 version of scandisk.exe will often fix floppy disks that Windows XP and the like won't read..." So now that laptop lives on, as the "The Mel's Thesis Memorial Laptop", in honor of the pseudo-irony of its provenance, whose sole purpose in life is to run scandisk on students 'dead' floppy disks, and actually fix them most of the time!
* Ok, it wasn't.
"These people look deep within my soul and assign me a number based on the order in which I joined" --Homer re:
My satellite internet connection needs a Windoze PC. Instead of dealing with this on my main PC, I use a stripped-down HP Pentium-II laptop as a router and small file server.
The top half with the screen is completely *gone*, and there's no battery, no floppy or CD. It's small, low-power, quiet, and gets the job done perfectly.
I also have a complete unit of the same kind, which I use with a wireless NIC. Opera and Firefox run great on it, and it's lighter, uses less power, and lasts much longer on its battery than the Toshiba Phatnote I have from work.
My house is off-grid (solar power and generator backup.) As a result, I tend to watch every KWhr more closely than the average technocrat, but the same concept applies elsewhere...
