# HP laptops power supply

Good morning
I've got two laptops last month in Best Buy, but I forgot to ask something.
In US the electricity is 100 waltts but in Chile where I am from is 220. So I'm wondering if I will have to use an adaptor or if the laptops can use any volts between 110 and 220?
Thanks in advance for your assistance.

Most laptops work with 110 and 220. You can verify yourself the power supply unit, it should have the following INPUT: 110-240 V or 100-240 or any other 2XX value. It means that it can work in 220.
The only thing you may need to buy is an adaptor for the plug if the US and Chile electricity plugs are different. You can find these adaptors in any electronics store as well at supermarkets. Ask for travel plug adaptor, it costs from 10 to 20 dollars.
I have two laptops in the US and I brought them to my country where we have 220 V and they are working fine.
Take care.

Well, as a rule for electronics:
The United States and Canada use 110-volt electricity.
Most countries outside North America use 220-volt electricity.
Unless your appliance is dual voltage, you need to use a "converter" or a "transformer" to change the 220-volt electricity into 110-volt electricity in order to use a 110-volt appliance.
If your appliance is dual voltage, you can switch it to work on 220-volts, without a transformer or converter.

HOWEVER

Desktop units have a selector switch for 110 / 220 volts., which is done away with in the case of laptop one's which sense the input voltage and regulate accordingly.

I think your main concern is just that you have an adapter for the plug to go into the wall outlet.

Hope that helps :)

### How to end Compaq CQ70 misery

I have owned a CQ70 for 2 years 2 months. Before I reveal my tips, here's my experience:
On purchase:
- quick start guide doesn't even show keys and switches, how to use camera, etc
- no software or manual supplied, only useless safety guide CD
- request for info to Compaq online: they returned a form to let them know how well they had served me when they hadn't served me at all
- subsequent requests unanswered
- complaint to www2.hp.com returned a worm called HTML-script-inf
First year:
- keyboard failed after 2 months; replaced under warranty
- screen failed after just under a year; replaced under warranty
- sound regularly disappears; have to reboot
- carrying bag burst within 6 months
- SD card reader worked intermittently for a few months, then not at all
Second year:
- I accidentally discovered the touchpad disable button; it doesn't work
- battery expired after 18 months
- replacement screen started to fail after 18 months
Now:
- replacement screen failed completely after 2 years 2 months
- I get electric shocks off the left side
- it generates constant flow of "Enter" commands; keyboard, mouse, USB ports cleaned to no avail; clears on reboot for a few hours (no viruses / worms - I regularly check)
- the HDD will not start spinning on mains power; I have to remove power cord and start on battery only, then replace power cord

Tip #1: I understand from a friend who works for HP that the good components go into the HP series and all the s*** into the Compaq series, so DON'T BUY COMPAQ.
Tip #2: If you have already bought one, put it in the bin or use it for landfill
Tip #3: If you want a reliable computer that will last for years, buy a cheap and cheerful Taiwanese no-brand. We've got two - they're great.

### Does cq61 laptop works without battery

I would assume that the wire/power supply is more likely to be the problem. Even if the battery is completely shot, most laptops will start if the power cord is plugged into the outlet and the laptop is turned on. You should check on replacing the power supply / power cord. Buy it from a store that takes returns with no questions asked. I've even bought one, tested it in the store, (after asking in advance if I could do so). This is a good idea if you live 40 miles from the place it's purchased.

### Have the HP-D3057F3H power supply - plug it in an the green light is flashing quickly - PC wont turn on - Is the power supply buggered or is it something else

Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as \$15 dollars Generic

### No power

To diagnose a problem with such limited information such as your problem, you have to start at the wall plug and work from there. It may be the AC/DC adapter is not providing electricity. It may be the battery has gone completely dead, in which case the laptop will not fire up. If it were a hardware problem, such as hard drive failure, ETC. the laptop would at least make noise, and at least display something such as a blinking cursor or beep a code. Was it dropped? Did it get wet?
With laptops, the solder of the plug hole at the back of the laptop gets weak and cracks because of the plug wire being pulled and constantly wiggling. check to see if the power socket at the back wiggles, If it does, a technition needs to solder a new plug, at a cost of about \$100. . Best buy sells new power adapters for about \$80-\$100
Good luck!!
