HP is notorious for this problem. The problem is that the power jack that is connected to the motherboard has come loose. This is an easy fix is you are comfortable taking apart your notebook and are able to solder the jack back to the motherboard. I have 2 HPs and my friend has 2 and we have done this with ours as well as others. This is the link to the HP website that has your manual for disassembly .http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang=en&cc=us&docIndexId=64179&taskId=101&prodTypeId=321957&prodSeriesId=1839143 When you get to the page, download the Maintenance and Service Guide. (It is all the way at the bottom!) You will need Adobe Acroabt to read it. PRINT the instructions. They will do you no good if they are on the laptop that you are trying to disassemble!

While it may seem daunting, it is really not hard to do. Just be careful to follow all of the disassembly and reassembly instructions and you will have no problems. I promise!


Please remember to rate my solution! Thanks

Why is my Sony VAIO VPCEB33FM green power light flashing?


It won't be the cpu. If it was, nothing would happen. I would look for a GPU issue, possible over heat.

HP Pavillion dv6700 - black screen


Do the following without the battery inserted.

Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...

Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.

These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.

Year old advent netbook 4211b will not turn on,


When you press power button press F1 or F2 or "del" key if you can see bios screen then you not need to refix RAM memory or reset bios.
IF you can see bios screen then lake sure harddisk is detected and SATA is disable then save settings and exit.
Also when you power up press F8 key if you able to see safe mode and other menu then you have change screen resolution enter in enable vga mode.
Then open control panel and display then change scree resolution to 1024*768.
Then apply and ok.
But if you can't see bios screen or nothing in dispaly then you have to refix RAM memory .
Check in back side there is 1 plate open it then refix RAM memory.
If still not get display then open back cover of laptop then find motherbord on it then pull cmos cell for 10 minutes so all settings go to defaults then again refix cmos cell then check.

Let me know if you need more assistance.
Thanks.

My compaq presario c765tu laptop suddenly turned off while i was working with that.then when i tried to turn on, only the power light comes, fan moves and dvd drive opens but the screen remains off.nothing...


If the problem is with the RAM or Hard drive then atleast you will get the access to the BIOS and this is not related to the hard drive or RAM as there is no display on the notebook.
If the Quick launch buttons are glowing then perform the following:
1. Remove the notebook battery and disconnect the AC adapter. 2. Press and hold the power button for a minute. 3. Reconnect the battery and AC adapter then try to turn on the notebook.
If the display still doesn't appear then, connect the notebook to external monitor and check the display on it. If there is any display on external monitor then the issue is with the LCD screen. If there is no display on external monitor then the notebook needs to be diagnosed by a technician at the service center.

Cannot turn on my LG Notebook anymore


Will the laptop boot with the power adapter connected and battery removed? If so, boot it up and install the battery once it's booted up. If okay now, the battery was just really really drained. If okay with no battery but no good with battery, the battery may be bad, or something in the charging circuit may be defective - keep the battery out or replace mainboard ($$$$ - get a new laptop)
If no good with ac adapter and no battery, test the adapter with an electrical meter. It should be putting out 18-19 volts. If not, try a replacement adapter. If adapter tests good but laptop won't boot with no battery, likely the mainboard.
Also - remove hard drive and try to power up. If good, replace hard drive. If no good, reinstall hard drive and remove ram and try to power up. If it powers up, clean the ram and slot contacts gently with a pink pencil eraser and try testing each ram chip in each slot, 1 chip at a time. If still no good, start shopping for a new laptop.

Let me know if this helps or not...

My computer won't start.


if the processor, ram and motherboard are working, there will be a display on the screen, check the processor, ram and motherboard through troubleshoot.
first: get working processor and ram then remove the ones in your system and then install the new ones, the display is on the screen, troubleshoot the removed processor and ram to find the bad one.

Acer travelmate 292elcI problem starting


Hi, sorry to hear you are having problems. When this happens it usually suggests that the CPU/system board has failed. If the laptop is still under warranty I would suggest taking it back because this is something that will be covered and they should be able to fix it or replace the laptop itself. If not you may have to pay to have the system board/CPU replaced. Good luck and hope this helps. Si :)
