I had a Hp or compaq tablet *with swivel screen. I have a hard time myself trying to get it to beam up. what a pesky switch. But I do know what happened to it before it started acting bad.... the spot where I plug in the power cord got extremely loose.. and i had to hold it just so with one leg of mine in the air one under me.. :D joke but you get the point. Just to try to get it to charge up. I didnt know if it was just the plug... I found out later with the help of a charging dock. That it was in fact the chargeing hole... After about 5 hrs playing with the cord in the charge dock to get it just right. It charged up for a measly hr or so. But since then when I use the charge dock the laptop will boot up...

Try googling for flash codes or light codes for the model of the laptop, and see if you can figure out what the flashing of the lights means.

Also, try booting from the power cord without the battery in, it might just mean a bad battery.

HP Compaq Presario CQ60 Won't Charge


Three blinks in a row is the LED code for a memory issue.

Turn the laptop over, remove the panel over the RAM, remove the DIMMs (it will likely have 2 in it), place one in at a time and try powering the system on.


One of the two is likely bad although it is possible (although very unlikely) that both are bad. It should boot up when the good DIMM is in place. Once you have identified the bad one, buy a replacement or possible choose to upgrade the total amount of RAM.

Compaq Presario V4000 laptop lower volume button (just to the right of the power on/off button) stays depressed. The button is concave now instead of convex. What to do?


Does the machine have regular keys (that remove) or a "blister switch" type key pad? Have you tried to use compressed air to remove any obstruction? OR try to pry the key, very gently, up? A LITTLE silicon spray? You may have to remove the keyboard. If you use the Tray Notification Area Sound Icon to increase volume what happens?

Compaq Presario V5000 does not come on


The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

Compaq presario cq61 won't turn on


hi
i wonder if the mainboard has suffered a power failure due to power shortage through electrical system that it was connected to . if the lights do not appear on the media strip below the video panel and above the keyboard, that would indicate a power failure has resulted from the power supply burn out. That being said the mainboard has suffered a electrical sudden power down. Have you tried the AC adapter to ensure it works ? I would need the entire model number and S/N of the notebook to get some feedback from HP

You need to replace your old battery. Don't over charged your battery. If you are using your laptop in your house it is better not to use it with battery. Just use the power adaptor/supply only. Then make sure you will drain the battery let say once a week. =)

Charging Problem


Your problem could be one of the 3 things:

a) the battery (about $50 to replace on eBay)
b) the AC/DC card which actually converts electricity into "juice" for your battery (probably around $50-75 + labor)
c) motherboard (for most laptops, between $200 and $400)

My recommendation would be to either buy a new battery first to see, since that's the easiest way to determine the problem ...or perhaps post an ad on Freecycle.org for someone to give you or let you borrow their battery just to test it out.

If the new or borrowed battery doesn't charge, it's options b or c

Hope this helps :)
