Some time ago I posted about installing Windows XP onto my new Acer Extensa 5620-6830 laptop. It's a nice little machine- the price was right, and standard specs aren't bad. But here's some information that could be helpful to anyone with this budget best Buy laptop and wants to get the most bang for their buck! Microeconomia Besanko.

Mar 29, 2017 - I suspect there is some bug in the driver of the native NIC of the raspberry (which is also an USB/ethernet adapter, but from Standard Microsystems by the way). I have no clue why it happens. Dan@blueberry:~$watch -n 0.1 'echo AAAAAAAAAAAAAAA netcat olive 1234'. Not got time tonight but over.
In conjunction with my other Instructables, this has some valuable tidbits specific to notebook computers. Contents: 1.Memory 2.Bluetooth/Wifi 3.CPU (hardware) 4.CPU (software) 5.Misc. Tweaks 6.Final thoughts. The Extensa 5620-6830 comes with 1GB of DDR2 memory.
That's two sticks of 512MB. This unit technically supports 4GB; 2 x 2GB modules. However, unless you're running a 64-bit operating system (if you have to ask how you'd know, trust me. You're not) then only about 3GB will be usable. There's no fix for this, it's just a fact. All standard 32-bit operating systems are coded this way. Due to this, I decided to purchase two 1GB modules (making 2GB total).
I find that to be plenty sufficient; I've never run out of memory in XP. Keep in mind, Vista will use about 1GB just to boot and run. You'll want to buy 667Mhz modules. There are 800MHz modules out there, but 99% of laptops on the market can't operate at that frequency. You'd be paying extra money for nothing, plus risking incompatibility.
There is an obvious single 'hatch' on the bottom of the unit through which we access nearly everything- wifi card, RAM, hard drive, and CPU. You'll need a small philips-head screwdriver to open this. You shouldn't have to apply force once the screws are out, though take note of the plastic tabs along one side. The stock hard drive is a TOSHIBA MK2035GSS 200GB drive.
It runs at 4200RPM, has an 8MB Cache, and uses Perpendicular Magnetic Recording (PMR) combined with Tunnel Magneto-resistive Recording (TMR) Head Technology. All that jargon supposedly means it's roughly as fast as a 5400rpm drive. I find it acceptable. There's faster drives out there, but is it worth wasting the $165 on a just to replace the original 200GB? You'd see a lot more heat, less battery life, and a big chunk out of your pocketbook.
The choice is yours, but I'm waiting for a faster (or equivelent-speed) 320GB drive. While our 5620 has a front switch and light for Bluetooth, the actual module is not installed.
Supposedly you can get one from Acer themselves. But be prepared to pay a small fortune. And know the part number. And likely have it shipped overseas.
There's two options for adding Bluetooth. If you're going to wait for overseas shipping anyway, why not buy a cheap ($6.99) little low-profile USB bluetooth adapter from (which works fine under both Windows and Mac). It takes awhile to arrive, but the one I got was cheap and works great. Best of all you don't have to crack your laptop open. Oh, not scared of taking apart your Acer?
