  2. About the HDD. Don't bother with wiping HDD, just buy a new one. Formatting often just sets files as "ready to overwrite", or deletes them (if seller does sell the PC with HDD, which is also not good, since nobody knows what new owner can do with seller's data).

  6. guys , Im thinking about buying older laptops , not too old but not the newest , they have some broken things but they are cheap and I'd fix the broken things , could I make profit and how do I know if it can be fixed?

  11. Some other tips for laptop hunting:
    -Have a general idea of what uses you will want out of the laptop. This would give you an idea of what specs you would want for it to get the most use out of it for your everyday needs.
    -Make sure the laptop has enough memory for optimal usage and check if the OS on it is a 32-bit or 64-bit system. 32-bit systems have a 4 GB limit they can properly address. 64-bit systems can access more, but should have at least 6 GB or more for optimal memory access and to reduce strain on the processors.
    -Have a large enough harddrive on it that will be able to store whatever programs and personal files will be installed and saved on it. It doesn't have to be a mammoth like terabyte drives. But you don't want too little storage either since the harddrive will still be reserving some space for system files the OS will need to properly run.
    -Have a set budget in mind for how much you would be willing to invest in the computer. Sometimes, the laptop you get's perfect. Other times, you may have to pay to make some fixes or changes to it. Just make sure what you may have to pay extra for in repairs or part replacements won't cost more than what you pay for the laptop, when you could get a better machine with all that money spent.

    My current laptop is a Dell Inspiron 15 3000 Series I bought used 3 years ago for $180 on E-Bay with a Windows 8.1 64-bit OS. Specs on it were decent for the most part, though it got a bit sluggish at points if I had anything fairly memory-intensive running on its 4 GB of RAM. So spent an extra $50 to max out the memory on the laptop's motherboard to 8 GB. Performance with handling multi-tasking and fairly memory-intensive applications improved quite a bit compared with the memory upgrade.

  15. Oh and also i use on a daily basis as a "typewriter" type computer a 2009 macbook and it works flawlessly. I run windows 7 on it though, since OSX versions newer than snow leopard are sluggish on it, and the thing is, you don't really find software that easily for a 2009 OS … unless it's windows and then you're golden, everything works really well. So it's obsolete, but still, it handles 99% of my daily tasks : check email, play music, go on social media and the likes. I also own a dell T7500 with 6-core intel Xeon and 12gb Ram (and plenty of disk drives in it) and it's a really good computer even by modern standards and it can handle video editing and music production … i paid next to nothing for it (130 euros a couple years ago) , the only thing i had to deal with was the noise. I didn't notice it was annoyingly noisy until it was in my living room, as i only could test it in a room full of servers with AC. Still very quiet for a server/workstation though, some of these are yelling that insane high-pitched noise into your ears and they're basically unusable unless it's some kind of web/file server put somewhere away from human ears. So yeah, "pro" computers can be had for cheap and they have the guts to run videogames and stuff but really do pay attention to details like this. I replaced most fans, got rid of the amazing but super noisy RAID array of 15krpm disk drives and now it's as silent as any standard PC. But yeah. I thought "wow i can run big audio projects on this ! " and then found out it was too noisy to really be useable as an audio PC (what's the point of low-noise audio interfaces and studio monitors if your computer goes "bzzzzzzzzzzrrzzzzzrrrrrrzzz" haha). Still, i could get the macbook (which is dead quiet) and the Dell for less than 300 euros , so i'm super happy with my computer setup : i have all the power i need, all the transportability i need and for really really cheap.

  16. also just power off and on the computer a few times. A friend of mine bought a macbook and it won't boot up if you power it off completely. It's not a big deal, the battery can keep it alive for a while when in sleep mode so my friend just closes the lid, and keeps it charged. we found a fix though : if ever the computer turns off (it can reboot, no problem, it won't just boot up if it's completely off even for one second) you can open it, unplug the battery, plug it back again and voila … but still , it means the computer can't be re-sold in an honest way (you could always scam someone else but that's just wrong in my book) without mentioning it and lowering its used price a lot, and also, it means you need to care about the computer being plugged in most of the time which is impractical.

  18. Another good tool for testing the screen is DeadPixelBuddy. That's for Windows, there is of course a Mac equivalent. I used it when choosing my first HP laptop brand new in the store back in 2006.

  20. computers can get obsolete so quick. Like when the PowerPC Macs were replaced by Intel Core Duos and Core Solos they became instantly obsolete. Usable, but not very up to date. Same thing when the Core 2 Duo was introduced. The Core Duo became obsolete in late 2006 and apple officially stopped making 32 bit software in 2011
