Acer Aspire One AOD150
Flip Netbook Upside
Unlock Battery Pack
This computer "how-to" guide was specifically written to assist owners of the Acer Aspire One 10.1" AOD150-1577 netbook in removing and upgrading the 2.5" hard disk drive or the RAM system memory.

Owners of other similar Acer Aspire One 11.6", 10.1" or 8.9 inch netbooks such as the AOD255E, AOD255, AOD532h, D255E, AOA150, AOD260, AO521, AO721, AO751, and AO533 may also find this guide to be helpful.

This Acer Aspire One netbook came equipped with a 160 GB 5400 RPM hard drive and just 1 GB of RAM.

I'd like to upgrade the HDD to a larger 320 or 500 GB unit spinning at a faster 7200 RPM or an SSD and increase the RAM from 1 GB to at least 2 GB.

The only tools needed to complete this procedure are a small Phillips head screwdriver and an anti-static wrist strap.

Remove Battery Pack
Battery Pack Removed
Unscrew Hard Drive Cover
The first steps are to power down the netbook, flip it upside down on to a soft towel or t-shirt, unlock and remove the battery pack.
2nd Phillips Head Screw
Pop Up HDD Cover
Hard Drive Caddy
Then unscrew the two Phillips head screws that hold the black plastic hard drive cover in place and lift it out of the way.

The two screws will remain attached to the hard drive cover, so don't try to forcibly remove them.

Be sure to discharge your static electricity by touching something metal or put on an anti-static wrist strap before touching the hard drive.

Lift Out Hard Drive
Toshiba 160 GB 5400 RPM
This netbook's hard drive wasn't held in place with an additional screw.

Check to see if yours needs to have another screw removed. If not, slide the hard drive towards the outer edge of the computer to disconnect the SATA connector plug from the socket on the motherboard.

Then lift the HDD and metal drive caddy out of the bay using the clear plastic tab attached to the bottom of it.

The drive should lift out easily from the bay without using excessive force.

Toshiba MK1652GSX
Remove Tray Screws
Remove the four Phillips head screws on the sides of the hard drive to separate it from the metal hard drive caddy.
Four Screws Removed
Lift HD Off Tray
Hard Drive & Caddy
Set aside the old hard drive and insert the new hard drive into the metal HDD caddy.

If you don't mind the extra cost, I highly recommend buying an SSD hard drive (solid state disk) since they are so much faster than traditional hard drives.

Re-attach the four Phillips head screws and tighten until they are just barely snug but will not vibrate out. Do not over tighten the screws or you may damage the new hard drive.

Netbook SATA Socket
Install New Drive
Slide SATA Plug In
Look at the SATA socket in the hard drive bay and the plug on the hard drive before attempting to install the new hard drive.

It will only go in one way so don't try to force it in.

Once the new hard drive is in place, slide it towards the center of the computer to plug in the SATA connector.

SATA Connection Secure
Lower Hard Drive Cover
Tighten Two Screws
Check that the two screw holes on the metal hard drive caddy line up with the screw holes on the computer's case. Then lower the hard drive cover over the bay and tighten the two Phillips head screws.

Acer Aspire One RAM Upgrade Guide

Hard Drive Installed
Ventilated RAM Cover
Unscrew Phillips Head
Two of the compatible 2 GB RAM memory modules for this Acer Aspire One 10.1" netbook include the Crucial CT934030 (2 GB DDR2 PC2-5300 667 MHz) for about $33, and the Kingston 2GB KAC-MEME/2G (DDR2 PC2-4200 533 MHz) for $40.

The single 1 GB RAM stick is located under a small ventilated cover near one corner of the netbook's underside. Remove the single Phillips head screw and set it aside somewhere safe.

Single Screw Removed
Remove RAM Cover
Samsung 1GB RAM
Pry up the RAM cover with your finger or a flathead screwdriver. This netbook was equipped with a Samsung 1GB 2Rx16 PC2-5300S-555-12-A3 RAM module.
Release RAM Clips
2nd RAM Clip
RAM Springs Up
Discharge your static electricity again by touching something metal or wear an anti-static wrist strap before touching the RAM.

The single stick of RAM is held in place by two clips that rest in notches on either side of the module.

Use your fingernail or a small screwdriver to carefully release the two RAM clips.

The RAM module will spring up at a 30 degree angle once the two clips have been released.

Gently grasp the RAM with your thumb and forefinger and lift it out of the socket.

It shouldn't require any significant force to pull out the RAM chip.

Pull Out RAM Module
RAM Removed
Insert New RAM
Insert the new 2 GB RAM stick at a 30 degree angle into the RAM socket.

It will only go in one way, so do not force it.

Secure the RAM in place by pushing it down until the two clips click into place into the notches on either side of the module.

Push Down To Clips
Replace RAM Cover
Tighten RAM Cover Screw
Replace the RAM cover and tighten the one Phillips head screw until it is just barely snug and won't vibrate out.

Then insert the battery pack and secure it in place using the lock switch.

Insert Battery Pack
Lock Battery Pack
Windows Booting Up
Flip the netbook back over and turn it on. It should start booting up your operating system right away.

If it does not, make a note of any beep codes that the computer might emit and remove the battery pack again.

Then try re-installing the hard drive and/or re-seating the RAM module(s) before trying to boot the computer again. If it still won't boot up, try re-installing the old hard drive and/or old RAM stick. If the computer boots up with the old hardware, you may have a faulty or incompatible HDD or RAM.
