SOLVED: HP G72 blinking power light

May 18th, 2012 admin No comments

This was a customer’s G72 laptop that had a little water damage on the keyboard. When I plugged it in to test it, at first it did nothing, completely inert, when the power button was pressed. I disengaged the battery and that seemed to fix that problem. Although I noticed that the power indicator next to the DC jack was either off or flaky, since the computer booted, I was happy…until I plugged in a USB keyboard and the computer immediately died. It would not turn back on. What it would do is lightly blink the LED on the power button about twice a second as long as I had it plugged in. No fans, no DC power light, no joy.

The HP forums are full of people with this problem and no solutions (friends don’t let friends buy HP laptops). However, it appears that this may be a simple solution, replace your power brick. I have a lot of them around here and the original unit I used on this machine was a 65 watt, I then tried a 90 watt which didn’t work either. Then I let the big dog hunt and used my 120 watt power supply and laughing I was. I got the idea from a tech in one of the HP forums who said that he could remove one RAM stick and get his to work but when he used 2 RAM sticks it failed, that sounded like a power problem to me.

Now, these HP computers drop dead from power and heat problems like honey bees in a Monsanto corn field so it’s possible that your unit is just dead. But, it could also be that your power brink simply can’t get it up like it used to and needs to be replaced. Here is the one that I used to get mine going. This is a cheap fix, I hope it works for you.

Solved: Sysfader debugger appearing on Facebook pages

April 19th, 2012 admin 1 comment

I had a customer who was using IE8 on an XP machine and could not get to Facebook. Whenever she went to Facebook she would get an error message pop-up that looked something like this:

Sysfader: iexplore.exe – Application Error
The instruction at “0x03b7fdb3″ Reverenced memory at “0xoooooo44″ , The mrmory could not be “Read”.
Click ok to terminate the program
Click Cancel to debug the program

Sysfader is apparently an Nvidia application so we reinstalled her Nvidia drivers with the latest version, still had problem. We then did a Reset from the Advanced Tab on IE8 and this changed the problem so that the Facebook page would open but it was for the most part blank. We got some page error messages in the lower left that were for “error: big_pipe is null or not an object”

Alas, most of what we found on The Google were people giving up and changing browsers or in one case getting a new computer. Here’s what we did that fixed the problem:

  • Uninstalled all Toolbars and junk programs using Add/Remove programs, specifically I remember Inbox Toolbar.
  • Uninstalled Facebook Plugin
  • Uninstall Google Chrome

I honestly do not know which of these steps solved my problem but Facebook now works.

5 Things to Consider When Choosing a Computer Repair Shop

April 9th, 2012 admin No comments

Finding a good person or company to repair your computer is the same as trying to find a good car mechanic, doctor, builder or contractor. You’re looking for someone honest, trustworthy and knowledgeable about their subject who will give you a good value and fix your problem without a lot of nonsense and hassle. Alas, the consumer is at an amazing disadvantage here because s/he often knows little about how the computer really works and is kind-of at the mercy of the tech they select – choose wisely.

But how to choose wisely? I’ve worked with a lot of clients who, let me say it honestly and plainly, have been ripped-off by their previous tech. There is a lot to write on this topic and a lot of sad and infuriating stories. Let me briefly sum up the observations I have made.

Don’t presume your prospective tech is some kind of genius.

Most techs I know are nerds, that doesn’t mean they’re smart, it means they get on with computers better than they do people. Based on my experience (and a Freshman year spent as a Psych major) I would guess the average IQ of the technicians I know is about the same as the population at large, 100. That means for every tech that’s a genius, there is one with a two-digit IQ. Now you’re no moron yourself (obviously, since you’re reading this blog), so don’t be intimidated to ask questions about what your tech (prospective or otherwise) is planning to do with your computer, what does s/he think the root cause of your problem is? What are the other possibilities? How will s/he determine what the real problem is? What is the procedure to fix the problem? It’s a cliche but there really is no such thing as a stupid question; if your tech makes you feel like there is, then find a different one.

Use those on-line repair services with caution

OK, I would say this, I’m a local tech and the on-line services are my competitors. But just because I’m not impartial doesn’t mean I’m not correct. I’m sure some customers have had good results from the on-line services, some have not. The customers that come to me after trying one of the online services tell me that they have spent hours on the phone trying to repair problems (you normally have to sit and watch them the whole time). I have had more than one customer that has been up-sold to virus repair when all they had was a simple configuration problem (in fact, I had a customer who took a brand new computer home from the store, had a problem with it, called an on-line service and was told she had a massive virus infection – the computer was brand new for goodness sake!). Again, I’m sure some of these guys are honest but the barriers to entry are small for this business and the accountability is very low if you have a bad experience. If you still think I’m making this up, here is an independent example: http://krebsonsecurity.com/2012/03/avast-antivirus-drops-iyogi-support/

Low-ball pricing is not uncommon, understand the full costs for repairs before committing to a technician or company

I’ve been doing this a few years now and I can tell you that I do not think it’s possible to make a go of this business if your average revenue per customer is under $100. Now, there are guys that are moonlighting and advertising on Craigslist for $25 and storefronts with signs claiming $50 repairs. Maybe these guys are financial geniuses or repair philanthropists but I doubt it. There are a tonne of hidden costs in this business, insurance, taxes, business licenses, postage on parts ordered and ones that are returned defective, out-of-pocket replacement parts for things that break while you’re fixing something else, lots of equipment, inventory, discs, hard drives, thumbdrives and DVD drives. The cost of software is significant. And if you have a storefront there is rent, heat and payroll. Make sure you understand the advertised price and the maximum price, the points in between and how your repair might jump from one to the other.

It is not normal to lose either your data or programs when you get a virus

I’ve written about this at length elsewhere but the quick version is that a good technician will be able to remove a virus from a computer without disturbing any of the user’s programs or files. Yes, sometimes it is unavoidable, the operating system can be so damaged it is either impossible or unwise to try and fix it, but this is not the normal case. A good technician will know when to do which but not until s/he examines the computer thoroughly.

Look for reviews and referrals but…

Internet reviews can be very helpful but there are a few things to watch out for. The way most review sites work (including Google) a crafty business owner can write all the reviews himself (in fact that’s exactly what one of my competitors in town has done). I assume it is intuitively obvious that this level of dishonesty is not a good sign for your doing business with a company. If you are reading reviews, look for specificity in the review and a diversity of customers. Look for whether the reviews are current, a bunch of reviews in a short time period and then no reviews often can mean that the business owner has hired a company to give him good reviews or s/he’s written them his/herself. You might also check one of the more reputable review sites. (Neither I nor many of my colleagues much care for Yelp where some claim to see a relationship between paid advertisers and good reviews but this is one place to go, Angie’s list is another one that I think is more reputable). The BBB is a good resource here as well, are they listed?

OK, next time I will write about 10 Questions to Ask Your Prospective Computer Repair Shop.

Solved: HP dv7 flashing power light

March 21st, 2012 admin 6 comments

OK, I have a customer computer here that is exhibiting the following behavior:

  • Front power light flashing when plugged in with battery inserted
  • Absolutely dead, no fans no lights when plugged in with battery removed
  • Computer starts and lights briefly when turned on with battery and AC connected

I have found a number of other people have had this problem and reported on HP forums and elsewhere but no one has ever reported solving it.

I believe there are two possibilities with this problem. The most likely one is that the DC power jack has failed and the computer is not actually getting full power from the mains (AC). I note on my computer that the light to the left of the DC jack on the computer is not lit – this is what leads me to believe in this case it’s the jack. I believe what’s happened here is that the battery is failing to charge and, with the DC jack bad, the laptop has no power and simply shuts down. The fix for this is to replace the DC jack. The hypothesis can be tested by finding a known-charged battery and starting the computer with it.

The second possible cause is a failed motherboard. Alas, this model computer (along with most other HP laptops)  has heat issues due to just a bad design by HP. This is exacerbated in some cases by a defective Nvidia graphics chip that was used in many of these units. Alas, there is no definitive test that I know of for this case other than changing the DC jack and finding that doesn’t fix the problem. If your computer does have this issue, the fix is to buy a new computer (not an HP or a Compaq, you’ve been warned). This is not a problem I would advise attempting to fix as the repairs are undependable.

I’m ordering a DC jack for my unit now and will update this with the results of the fix.

SOLVED: TurboTax 2011 installation fails because of .NET 4 problems

January 29th, 2012 admin 13 comments

My customer was trying to install TurboTax 2011 on his Windows 7 x64 install and got into an endless loop where TurboTax wants to install or “correct” some issue with Microsoft .NET 4. Alas, allowing the software to do this just results in the computer re-booting over and over again, hopelessly trying to do something with .NET 4. If you look under covers, you’ll see you’re getting an error 0×80070643.

Looking at Intuit’s site, it appears that their ultimate fix for this is to recommend abandoning their product and using the online version <shrug>. Here is what I did to fix the problem.

  1. Uninstall Microsoft .NET 4 using the control panel and add/remove programs
  2. For good measure, you might want to disable your antivirus program, I did, but I doubt this was necessary
  3. Download the .NET clean-up tool from the second part of this Microsoft kb article and clean-up .NET 4
  4. Go to C:\Windows\Microsoft.NET and change the name of the folder called “assembly” to “assumbly2″ as described in this brilliant solution by irarab.
  5. Reboot
  6. Download the .NET 4.0 installer from here and run it, .NET 4.0 should now install successfully.
  7. Try your TurboTax installation disc now

If this works for you, please leave a comment below. Also contact Intuit and tell them they owe me a commission for fixing their customers’ problem for them.

 

Solved: Still can’t run .EXE after registry fix

January 12th, 2012 admin No comments

I have a number of tools to fix registry problems here for various operating systems. However, I got a Windows XP machine in today that had been screwed up so bad none of them worked. Normally, a quick run of my registry fixer does the trick but neither it, nor the one recommended on the Malwarebytes site, nor Malwarebytes solved the problem. This computer had Pareto Logic’s File Cure program on it; a program, since it has no actual value, that must be evil and I suspect contributed to this problem.

Finally, I found a more complete .EXE registry fix file that did the trick. I downloaded the one for XP and it worked like a charm.

Solved: Windows Task Manager does not update

December 15th, 2011 admin 1 comment

A customer brought me a brand new Acer desktop computer and wanted me to fix a borked install of Microsoft Office 2000. When he opened the Task Manager, he saw that the machine was (seemed to be) stuck at near 100% CPU usage.

When I opened Task Manager, the first think I noticed was that the CPU usage was indeed at 100%, but that it also never changed. If I went to the processes tab, the individual processes never changed the amount of memory they used or CPU. How could Task Manager be broken?

Well, the fix was easy (as they all are once you know the trick). Somehow, the updating of task manager had been set to “Paused”. To fix the problem, I went to View–>Update Speed and changed it from “Paused” to “High”. Problem Solved.

Solved: Missing Base Filtering Engine in Windows 7

December 12th, 2011 admin 34 comments

UPDATE 21 Jan 2012:  If you are missing just BFE, the information below should be helpful. However, if you are missing BFE, Windows Firewall, Security Center and a couple of other services after a virus infection, you are going to need a more comprehensive security services fix. The second post by Farstrider (that starts “you can also try this:” works great. After getting the Norton 5013,3 error on yet another customer computer, I found this solution fixed the Norton problem without requiring me to reinstall the OS. HOWEVER, even still the Security Center service was still not starting, fixing that required me to download and run the Security Center registry entry from here (reboot afterward). Good Luck.

It looks like there is a virus now that can take out the Base Filtering Engine Service in Windows 7, and I suppose then in Vista and XP as well. I noticed this problem on a computer that I removed a virus from. Everything looked fine until I went to install Norton Antivirus and it barfed with an error message about Error “5013,3″. The instructions to fix the problem included restarting the Base Filtering Engine Service but oops, it wasn’t even there. As it turns out, the fix for this is easier than you might think.

The fix I used was to recreate the BFE service entry in the registry, which had been deleted. The registry entry that needs to be recreated is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE

According to this Microsoft Technet article, you can just export the key from a working machine of the same OS and import it (just double click on the exported and moved .reg file) into the problem machine. I can tell you this absolutely worked like a charm for me.

WordPress won’t let me attach a copy of my Windows 7 x64 BFE entry, but if you need one, this link should work, otherwise leave a comment and I’ll try and mail it to you..

 

SOLVED: 0x7B after rootkit removal

November 8th, 2011 admin 5 comments

I have two Windows 7 computers in for repair right now with the same bootkit virus. Kaspersky’s TDSSKiller identifies it as Rootkit.Boot.SST.b. This is a bootkit virus that I found was impossible to remove with the host disk in the machine, it has to be mounted externally and slaved. After removing the virus however, both machines refused to boot and returned an 0x7b BSOD.

After a bit of flailing about, I found that in both cases the proper boot partition was not listed as “Active”, on at least one of them, the recovery partition was set to active, the other one I did not check. To fix the problem, I did the following:

  • Set the Windows partition to Active using Diskpart from the repair console (WARNING: if you use F8 to get to the repair console, make sure you have a Windows 7 boot disc around because this procedure could leave you unable to get back to repair console using F8, instead returning “BOOTMGR Missing”. If you get to that point without a bootable Windows 7 disc or Windows 7 repair disc, you are totally screwed as far as I know)
  • Run Bootrec /FixMBR and Bootrec /Fixboot
  • Reboot.
  • If you still have issues, reboot to the repair console and have it do a start-up repair (I had to do this twice on both machine)

OK, that’s how I fixed it. Good luck.

Solved: Dell Latitude boots into Diagnostic Mode every time

October 7th, 2011 admin 2 comments

My customer needed his computer repaired. It was a Dell Latitude e6400 that had the following weird symptoms:

  • Power button does not work – The power button would not turn the computer on or off
  • Computer boots into Diagnostic mode – Every time the computer starts up, it would say “Diagnostic Boot Selected” and try to run through its diagnostics

The only way to turn the computer on and off was to unplug it.

After removing the hard drive, RAM sticks and keyboard then unplugging the CMOS battery, the computer still did the same thing. As it turned out the simplest fix worked.

Let the diagnostics start, hit escape when it’s available and tell the computer to reboot, quickly start hitting the F2 key to get into BIOS setup. Once in BIOS, click the “Load Defaults” button, Apply, exit, reboot. This fixed my problem, I hope it fixes yours.
