this alone won’t likely work, if not, continue:

if you skip this you will get this error: flashromPartialWrite() so read on carefully

you’ll haft to get into the system and remove the rewrite screw. on the Acer Chromebase 24 if a bit difficult to open the case, but very doable. 3 screws at the bottom and then a couple pry tools should do the trick, unlike most laptops, or other all in ones, this particular model is difficult to get in simply because of the rigidity of the plastic and design. lay it on its face, remove the stand, then the 3 screws at the bottom edge, once those are off, its a matter of prying the back off. once this is done, you will see a whole lot of sheet metal covering all the electronics, remove what you can and you’ll find a motherboard and on this motherboard is the rewrite screw, take it off and boot the machine back up.

get yourself into developer mode then type (Ctrl-Alt-F2) to bring up the command prompt then follow the steps below

Type: chronos

Press Enter

Type: sudo su

Space after “vpd”, Space after “-s”.

The Product S/N will be the Serial Number without the last letter. Make sure the serial number is CAPITAL letters.

Press Enter

If flashromPartialWrite() error displays go back to the Read/Write Copper where you have removed the sticker and re-clean the area with alcohol and try again. Make sure you shut down the chromebook and remove the battery before cleaning.

HP laserjet p2015dn print issues

so your HP printer suddenly stops working.. and you get a blinking indicator light.. if your lucky you may get a little usage out of it by turning it off and on again. but even then it still eventually stops working. and for the rest of us.. it doesn’t work at all.

the HP LaserJet p2015dn


The Problem: your printer will not print, you’ve already troubleshooted every possibility you can think of and your suspicious that your HP laserjet p2015dn printer needs a new formatter board.

The Solution: bake your board: other then replacing the board or buying a new printer this is your only viable option.. and even this isn’t full proof.

  • Remove the formatter board and remove the tape near the memory slot (if there). Prop up on four corners and place in a baking pan chips facing up and make sure the bottom of the board does not touch the pan. Preheat regular oven to 350F (177C), place in oven for 8 minutes. Remove and let cool for 30 minutes and put back in printer.

I can vouch for the method above, it worked for me.. there’s a lot of talk about this method in the HP support forums and a lot of users are seeing success to varying degrees (pun intended) I’m adding the how-to here for my own reference and hopefully for someone else to stumble upon.

Please wait while windows configures Microsoft Office Professional Plus 2010

The Problem:

Every time that you open a Microsoft Office 2010 application, you receive the following message: “Please wait while windows configures Microsoft Office Professional Plus 2010.”

Possible Solutions: (reboot after doing any of these)

  1. Uninstall everything Office related then run this utility
    Windows Installer Cleanup Utility:
  2. Problems with uninstall? Go to:
  3. try running the SubInAcl tool:
  4. This may work for some users.
    Start -> Run -> reg add HKCU\Software\Microsoft\Office\14.0\Word\Options /v NoReReg /t REG_DWORD /d
  5. Go to start ->programs -> accessories -> command prompt (Run as Administrator). Use the following command: secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

With the exclusion of number five I tried all of these to no avail.. after spending 2 hours troubleshooting I decided the best thing to do was to backup and reformat the drive. my suspicion being that there was more at play here then I could see.
