Accessing memory and hard drive on an Acer Aspire One D257

The Acer D257 is a lovely netbook but most come with just 1gb of DDR3 memory in its single memory slot. There is no simple cover to access the memory (or the hard drive) instead the keyboard has to be taken out, screws removed to release the bottom compartment helpfully labelled as “door” and then finally working out how the “door” is removed. Below are the step I took to access the memory and hard drive.

Firstly remove the battery from the netbook and then the keyboard has to come out. There are 5 tabs at the top of the keyboard that hold it in.

Arrows indicate tabs that hold the keyboard in place.

Using a small flat-bladed screw driver gently push the tabs in whilst using a sharp instrument such as a Stanley knife to lift the keyboard. I find starting at the centre best.

Once the keyboard lifts out detach the ribbon cable by lifting the brown catch up and sliding the ribbon out.

This will allow you to access the 5 “door” screws. Remove these screws.

The “door” is now only held in with 3 tabs near the battery compartment. To remove the “door” I slid the Stanley knife in at the front of the door pointed to by the red arrow and then moved it backwards using the none blade edge, flipped the knife over and then slid the knife the other way. Once the “door” is lifted at the front you can slide the plastic cover back and all will be revealed.

Red arrow shows where to start lifting the "door". Blue arrows show which way to slide the door.

Now you can access the memory and the hard drive.

Windows 7 The user profile service failed the logon. User profile cannot be loaded error

This error occurs when Windows 7 has a problem, tries to resolve it by backing up the user profile in the registry and creates a new faulty one for the user. This fix restores the original entry in the registry. The problem is that you cannot log on to your computer to edit the registry. Therefore this is a two part fix, the first part is to enable the computers built-in administrator user and the second part is the registry fix. I have added a third part which is what else to try. I have had 100% success with this fix however so far only five machines have come in to be fixed. I have never had to try part 3…. so far!

Part 1 – Activating the built-in administrator user

1. You need to start the computer in “Safe Mode with Command Prompt” to do this start your computer and hit F8 multiples times after the initial BIOS screen. You should see see a menu screen. If you see the Windows splash screen then hold down the power button for ten seconds and then repeat this step.

2. Highlight Safe Mode with Command Prompt and hit [Enter]. Try logging in there. If it still doesn’t work, then go to step 17.

3. If you are able to login, once a command prompt pops up, type:

net user administrator password /active:yes

You can specify whatever password you want for the administrator account.

4. If you get a message saying “The command completed successfully”, then restart your computer by typing: shutdown -r. If not go to step 17.

Part 2 – Editing the registry

5. Boot up again pressing F8, but this time select Safe Mode – not the Command Prompt.

6. You will be able to login as Administrator with the password you set in Step 3.

7. Hold down [Windows logo] key  + [R] key.

8. Type regedit[Enter]

9. Once in the registry editor, use the left window to navigate to the key:

HKEY_LOCAL_MACHINE

SOFTWARE

Microsoft

Windows NT

CurrentVersion

ProfileList

10. In the left pane, find the one that starts with S-1-5….. and ends with .BAK. If you don’t find one, skip to step 15.

11. Right click it and click Rename, then change the .BAK to .BK

12. Right click the one with the same numbering but without the .BAK and add .BAK to the end.

13. Right click the one that you renamed to .BK and click Rename, delete the .BK

14. What you are doing is switching the one with .BAK to the one without. This should be enough to fix this problem.

Part 3 -What else to try

15. If you didn’t find a .BAK entry in the registry then open Windows Explorer to:

C:\Users\Default\AppData\Local\Application Data

You will have to show hidden and system files to do this.

16. If you find another Application Data below the one you’re on, then delete it. That should fix your problem.

17. If you can’t login in Safe Mode, then reboot and hit [F8] until you see the menu again, then select “Repair Your Computer”.

18. Wait until all Windows Files finish loading, then hit Next when it asks keyboard language.

19. Try logging in here. Select your user from the drop-down menu, and type the password, then jump to step 23

20. If that still doesn’t work, then if you have your Windows Installation DVD still, put it in and restart your computer.

21. Hit the correct function key to boot from the DVD or change the boot order in the BIOS (Setup).

22. Choose keyboard language then hit next. Find “Repair Your Computer” from a little below the centre left.

23. Choose Open Command Prompt and type:

net user administrator password /active:yes (again you can specify a password)

24. Close the command prompt and click Restart and jump to step 5

Finally

To disable the administrator account, type this in an elevated command prompt:

net user administrator /active:no

Good luck!

Advent Roma 1000 Overheating

Normally when a laptop overheats it just switches off. In the case of this Advent Roma 1000 it would blue screen.

I knew the blue screen was caused by hardware as I had only just installed Windows and drivers before the laptop started blue screening.

Luckily the heat sink and fan are easy to get at on an Advent Roma 1000.

Undo all the screws holding the large compartment cover on and then lift it off from where the arrow is pointing.

The heat sink should now lift up. Be careful as the copper pipe can bend.

The dust collects between the fan and the exhaust under the black tape.

Using a paper towel remove the old thermal paste from the copper heat sink. Also remove the residue from the CPU and Graphics Processor (GPU).

Recovery of Outlook Emails and Contacts After Factory Restore

outlookA very disgruntled customer brought an Acer laptop to me. She had previously been infected by a virus and the shop she had taken her laptop to performed a factory restore to clear the problem.

Note: Only in extreme circumstances should a laptop require a factory restore because of a virus.

The shop had backed up her documents and photos but had not backed up the customers email settings or more importantly her Outlook 2010 data (.pst) files.

Recovery of her email settings was simply a phone call to her ISP which she had done but losing her business contacts and emails was disastrous.

I removed the hard drive from the laptop, put it in one of my external USB3.0 hard drive readers and after a two hour scan I recovered both of her Outlook files. I then imported them back into Outlook.

This entire process took about 5 hours and I charged her just £50. She said she would have paid four times that amount as the emails and contacts were so important to her business.

If you have accidentally deleted folders and files then please contact me and let me try and recover them.
