Since this got revived, I guess this is another forum where I talk about the Toshiba Satellite L750 laptop I bought 11 years ago. At least I missed the Intel chipset bug (early Sandy Bridge), but every single part of that laptop either performed horribly or failed unusually quickly.
The CPU was a low-end Core i3-2330M. It benchmarks better than every Core 2 Duo, but performs worse than most of them in real software. For some reason, saying that really upsets people. I eventually found one other person who mentioned strangely poor performance on a different laptop with an i7 from the same generation.
The Intel integrated graphics had totally broken drivers. Most software I tried wouldn't allow hardware acceleration to be enabled, despite meeting the minimum requirements on paper. It also gave random BSODs while using hardware H.264 decoding. Intel didn't release an updated driver for four years, and then they silently put the new driver on their website (but not Windows Update - I had to watch the list of updates to make sure Windows didn't "update" to the broken driver that the laptop shipped with because hiding an update in Windows 7 just meant "install silently a few months from now without the user's knowledge"). Then they put a bunch more "older" drivers on their website that definitely weren't there on their claimed release dates. The latest driver was more stable, but 3D acceleration was still broken. I guess I should have spent the extra money on a discrete GPU, but I didn't have that much money.
The 1366x768 display was already unusable due to its low resolution (and partially because it was a glossy panel) when it was new, but the only way to get a usable resolution on a laptop at the time was to either get a workstation or a 17" screen. It also had horrible black levels (more like light gray at minimum brightness) and the worst color quality of any color LCD I've ever seen.
Sequential read/write speeds for the hard drive dropped over time (down to 50MB/s), but the drive performed as expected in a different computer.
The keyboard failed after three months while only using it for school (not heavy typing).
The touchpad had an unusually low pointer speed, and no touch features worked (not even tap-to-click or edge scrolling - tapping would just make the cursor move slightly, and the edge scrolling region was about 1mm wide), and it was just a lightly textured patch on the palmrest with no well-defined border.
This was probably the only new computer in late 2011 with only USB 2.0 ports. There was an unpopulated footprint on the motherboard for a USB 3.0 controller that was covered with black tape. The USB ports became loose unusually quickly, and I had to regularly clean them because even external mice would become unreliable (including random movement and clicks, which I didn't think was possible for a flaky USB connection). What eventually made me get rid of this laptop was a USB 2.0 composite/S-Video capture device producing garbage frames without high CPU or disk activity and transfer rates to an external hard drive dropping to 15MB/s at the same time.
The built-in speakers were barely audible in a quiet room at full volume and eventually stopped working entirely. When the speakers stopped working, the audio codec (which had a built-in amplifier) got hot enough to make a warm spot on the outer case. Headphones still worked until the jack failed with no stress (nobody yanked on the cable).
The RAM failed after four months (not Toshiba's fault), and it took months to get it replaced under warranty. Toshiba wouldn't accept it back until I reinstalled Windows (claiming that errors in Memtest86 meant that Windows files were corrupt), and then they would replace one random part and send it back to me without testing. On the first repair attempt, they even claimed that they fixed a problem that I wasn't having. Eventually, they sent it to an authorized repair center instead of their own repair center. That other repair center made it stable, but they also did something that cut the battery life in half. Reinstalling Windows increased battery life a little, but it didn't get all the way back to normal.
I'm probably missing something here, and this post is already really long. I used this thing until 4GB of RAM wasn't enough to run Firefox (the "quantum" releases), and when I upgraded, I was told that this pile would be just as good as any new computer if I just put an SSD in it. That was the shortest amount of time I've ever kept a computer, and it was only because I didn't have the money to upgrade for that long. I kept it around for video capture until the USB failure I mentioned above. Then I got a ThinkPad P53. I did regret buying that for a while, but the only laptops I found that looked like what I wanted (for example, the AMD version of the ThinkPad L15) were only sold in Europe.
