Fix HP Blank Screen Error

Sunday, March 13, 2011

Problem :

While booting up the power cord was pulled out. This turned the computer off because I just plugged in the power cord.
Now when I try to turn on the computer it only shows a blank screen and nothing happens. The wireless light and power light lights up though. Think the BIOS is damaged.
This is a HP Mini 110 1191 eo.
Is there a built in bios recovery system? I know some other producers have a built in bios recovery system, so you just have to download the newest bios and put them on a usb and then press esc + ctrl while starting up.


Solution :


If the computer display remains blank and does not boot into Windows, or some device stops working, or the computer freezes, it may be helpful to perform a hard reset. A hard reset will erase all of the information in the computer's temporary memory and restore functionality. Many times, peripheral devices like USB drives, firewire devices, USB memory sticks, and even SD cards can interfere with the normal boot process. Doing a hard reset will force the system to clear and then reestablish the software connections between the BIOS and the hardware. Other problems that can be resolved by performing a hard reset include the keyboard not responding, or the PC not coming out of hibernation or sleep mode, or the PC freezing during normal operation.
When performing a hard reset, you must disconnect or remove all devices. You should start and test the computer by itself, and then reconnect one peripheral device at a time. To resolve the start up or operational problem, you should run the HP Support Assistant, or manually install all updated drivers from Microsoft and HP.
Performing a hard reset
To perform a hard reset, follow the steps below.

1. Unplug the AC adapter from the notebook PC.
2. Remove the battery from the notebook battery compartment.
3. Remove the computer from any port replicator or docking station, disconnect cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices.
4. Press and hold down the power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
5. Insert the battery and plug the AC adapter back into the notebook PC; but do not connect any of the peripheral devices.
6. Press the power button to turn the notebook PC back on.
7. If prompted to boot into Safe Mode or select a special type of start up, use the arrow keys to highlight Start Windows Normally , and then press the enter key.

After reconnecting each of the peripheral devices, you should run Windows Update and HP Support Assistant to update all device drivers.

Fix C000009A Error on Win 7 SP1 Install

Monday, March 7, 2011

Problem :

Have tried this on 5 machines today - got the C000009A error on 2 of them - the only fix seems to be the DISM revert command shown in this thread. All 5 had ALL language packs installed and where fully up-to-date with all Windows Update fixes prior to the install. The 2 that failed where a brand new i5-based HP laptop that was a clean win64 ultimate install, and a core i7 gigabyte x58 mobo loaded up with 5T drives and 12G ram also a win64 ultimate machine - been running fine for a while. 2 other machines, both i7-920 x58 gigabyte units running win64 ultimate w/all language packes installed, took 12 hours to get 1/2 way thru the progress bar - "cancelled" at 12hrs - hopefully they will succeed at cancelling...;) 5th machine is a ibm/lenov TP 410 core-i5 laptop - cancelled after 10 hours at 1/2 complete. That's 0 for 5;) Guess I'll wait for a bit before attempting this again.

Solution :

1. Do a normal shutdown and then bring the system back up;

2. Go to Start and right-click on Computer. Then click on Properties. If you see (4th or 5th line down) Service Pack 1, then you are done. Presumably you will not see that line.

3. It is the Language Display packs that create the problem.
Go to Start, Control Panel, Region and Language > Keyboards and Languages > Install/Uninstall Languages > Uninstall display languages. Then click EVERY language there, except English. Then uninstall. This process will take about 1 hour, maybe longer.

4. Your computer will probably reboot after this process is finished, but if not, do a reboot.

5. Go to Start, Control Panel, Windows Update. You should see SP1 still listed there. Click on it and install it. All (or most) of the files that SP1 needs for its configuration are already in place from your earlier failed install, and the installation will go faster than the first time. The process does have (heart stopping) pauses, where it seems that nothing is happening, but just be patient and let it go through its paces. The system will reboot when the blue line is all the way to the right, and Windows 7 will come up, and will continue to configure SP1, so it is a slow process.
You will, however, not see those fast-moving lines: "Applying update operation nnn of nnn" until an error stops the process, but instead there will be a "nn% complete" display. Let it do its thing without interference. This also will take some time.

6. You may confirm that you now have SP1 installed by repeating step 2 above.

7. You can now also re-install one or more display languages by repeating step 3, and after clicking on Install/Uninstall languages, install the languages you need.

Fix Windows 7 Ultimate SP1 Error Code c0000034

Tuesday, March 1, 2011

Problem :
Machine is x64 (intel core i7), with 8gb memory tried installing sp1 via windows update. there were three patches to install, one of them, sp1 did the two first, before, and then tried sp1.
It failed while rebooting (not remember the code, sorry), but i was able to do a system restore to pre-sp1. then, got the full SP1 media from msdn, and did install it in offilne mode. Setup looked faster (of course?) and in reboot, this fatal error c0000034 appeared. But this time, no option for system restore.


Solution :

Reboot and press F8 right after the Bios Screen.

Select Windows Recovery Environment [this should be the top option].

Select keyboard option and login for your account.

=> Open the "Command Prompt"

=> find your Windows directory (my PC was on D:)

=> cd to Windows\WinSxS folder

=> type in this command move pending.xml pending.old

=> exit command prompt

=> run "System Restore"

=> select the option for Service Pack 1

=> exit and reboot
