Question about HP Pavilion dv4000 Notebook

HP Pavilion dv4000 does not power up.

Last time I've used my laptop, it was low on power, I sent it to hibrenate
and then left it.
after couple of days, I came to turn it on, plugged it into the ac adapter, and nothing happens, just a black screen.
I've notice 3 blinking lights on the front nothing else.

HELP!

I have had this happen a couple of times but not sure if its the same for you. There is a small button on the upper right that engages whenever the laptop screen is closed. I was experiencing the same thing when I accidentally brushed the button. I didn't notice anything happen but, I next pressed the power button and it came on???? I guess there is some dohicky in there that triggers the off feature. I haven't decided to ignore this with software yet.

I saw this while researching charging issues where a new battery is installed, calibrated and now will not charge?? any ideas?

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start


Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

Bluetooth & sound


Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

Try the following: Using your FN key and the F7 Key together it might work again. You could have toggled the touchpad off. If that does not work you have issues with either the touchpad or the operating system. Best of Luck.

HOW TO ENABLE BLUETOOTH IN THIS NOTEPAD ?


The Acer Aspire is a high-performance laptop that includes a fast processor, widescreen display and an internal wireless card. In addition to these premium features, certain models also include one-touch Bluetooth access. If you have an Acer, enabling the Bluetooth is very easy and will only take a few seconds.

1.Turn on your computer and wait for Windows to fully boot. Then log in as an administrator. You will not be able to use Bluetooth under a non-administrator account.

2.Press the button with the Bluetooth symbol on the left side of the computer. This will launch the Bluetooth utility. From here you can sync and manage Bluetooth peripherals.

3.Press the Bluetooth button again to disable Bluetooth. This will disable all connections, but the utility will save your settings so the same devices will sync with the computer again when Bluetooth is re-enabled.

I hope you may find it very helpful.

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
