Collecting vintage laptops or vintage equipment with lcd screens is just not a good idea. Laptop boards are very tricky to repair, there are no spare parts for the most part and the screens are all going bad with practically no replacements out there.
Toshiba was a great laptop from the mid 90s into the early 2000's but thats irrelevant in the long run.
If you find a well built laptop with a reliable LCD panel, you will be fine. The biggest thing with LCDs is that they are stored in CLIMATE CONTROLLED conditions. Extreme heat and humidity is a death sentence to them. All of my important laptops are stored inside. And you absolutely CANNOT stack laptops on top of each other to store them, especially not old 7-10 pound units. The weight of the machines will cause severe damage to the LCDs at the bottom of the stack. Laptops should be stored like books on their side, never stacked.
The only issue I see with most LCDs is the “vinegar syndrome” where the adhesive for the LCD polarizer bubbles up, but that’s actually entirely fixable if your willing to put out the effort. The new polarizer film is easy to get.
Some LCDs however are more prone to failure than others, and I would definitely avoid machines with high LCD failure rates, such as the Epson Equity 286/386 laptops. The LCDs are garbage on those.
Battery leaks can be a concern, but laptops are by no means the only computers with that issue. I make sure to disassemble all of my laptops as soon as I get them and remove that evil green pack of cells.
I’m roughly 12 years into my laptop/computer collecting journey and I really haven’t noticed things failing more now than they did 12 years ago. I see some people say “they are all going to fail soon,” but where’s the proof? Hell, most of my old hard drives even are holding up perfectly fine.
But if you take absolutely no care to remove any batteries and store them in a humid environment, then yes, they absolutely won’t last much longer.
A good example is, out of the twelve Compaq SLTs I’ve owned over the years, I have seen one, exactly one, bad LCD with lines on it. Ironically, that ONE machine had mold and dirt all over it and looked like it had sat in a leaky barn for 25 years. The way they are stored is everything.
Guitars are the same way, heat and humidity will absolutely destroy them, especially a hollow body or acoustic. Yet, they can last decades and decades if they are cared for and not exposed to extreme conditions.
