You cannot update your BIOS on battery power because if your battery dies while updating the BIOS, your PC will not function at all because the BIOS would be corrupt. So your PC won't take the chance of that happening.... smart PC..

Your PC doesn't recognize your A/C adapter?... then you either have a bad A/C adapter, or a bad charger port on your motherboard. either way you will have to buy one or the other in order to update your BIOS.

you shouldn't NEED to update your BIOS... u can live with an older version

My screen flicks alot or sometimes the desktop goes black and then reappear


Hi! try this steps. First reinstall your video card driver. Uninstall the first one then install back the driver. Second update your computer BIOS driver . (BIOS driver can be found on the website of HP as well) But make sure that if you update the Bios your battery charge should be above 30% or more than that and should be plug in the Ac adapter. Because if there will be power failure while updating it, motherboard will be defective .... Just to make sure call HP hotline for further assistance. Hope this will help you . God Bless.

Shutdown


if it is in a no power no boot situation you will have to replace the bios chip or replace the motherboard. if you update the bios ALWAYS MAKE SURE YOU ARE ON AC POWER AND HAVE A FULL BATTERY. if your battery is weak make sure the power cord is plugged in and secure . if your computer looses power during a BIOS update it is bad .

Not charging


which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

What else?


You need to go into BIOS by pressing F2 at startup and then choose the option saying restore defaults.

Once this is done. Visit the manufacturer's website and the download the latest BIOS. Once this is done the AC adapter will be recognized. It has nothing to do with the Hardware itself

My hp laptop battery shows 100% but will not power up the computer


If you are using a dv series pavilion Notebook and is preinstalled with Windows XP, you need to download the HP Battery Health Check utility from the link below and run in the Notebook to know the status of the Battery :
ftp://ftp.hp.com/pub/softpaq/sp41501-42000/sp41862.exe

Follow the instructions to perform Battery Check in the Notebook :
Insert the AC power adapter into the notebook PC and plug directly into a wall outlet.

Click StartAll Programs, then click Hewlett-PackardHP Battery Check.

If the Battery health status is good, I recommend you to check with updating the BIOS by checking with the Product Number of the Notebook.

Laptop won't run on battery power


Have you tried a KNOWN good battery? If your laptop does this with a battery that's known to be good, then the charging circuity is at fault. Also, try this: while the AC and battery is plugged in, unplug the battery. If nothing changes, then the laptop is the problem, if the status changes, then the problem MIGHT be the battery(ies).

Hope this helps, and please rate my advice.
Thank you, and good luck!!
