Are loptop internal power supplies soldered onto the laptop?

most don't have internal power supplies, that is the little box in the cord, some do, and no they can be removed and changed, which laptop do you have

Current PC power supplies (I'm assuming a desktop or tower style power supply here) have several types of wiring coming out of them. I'll list them with comments. \n\n--Flat 4-pin inline wite plastic connectors, lots of them. These are power connectors for devices like disk drives. Polarized and can't be inserted backwards. Usually 4 multiply colored heavy guage wires to each connector. Not all of these must be connected.\n\n--Large 2 row white plastic connector (about 20 pins) which is the main power conenctor to the motherboard. Also polarized and can't be inserted backwards. 1 of these. Must be connected to the motherboad.\n\n--Small 4-pin connector, perhaps as many as two. Power connector for small drives (like 3.5" floppy drives). Not all need to be connected to drives.\n\n--Up to two additional connectors for the motherboard. One will have 4 pins, and one 6 pins (if memory serves). They are polarized and can't be inserted backwards. These are additional power supply lines for high current motherboard circuits. If present, and the motherboard has matching sockets, they should be connected. If the motherboard has no matching connectors, leave unconnected. If the power supply doesn't have them, and the motherboard does, stop. Carefully consider the total current draw of the various components on the motherboard and attached to it. You might have to (likely will have to) get another power supply to safely satisfy the motherboard's needs.\n\nIt may be useful to know that a great many power supplies don't actually behave very well. It's not easy to design a reliable supply with good perforomance at a reasonable price and in the size constraints within which a standard power supply must fit. A misbehaving power supply can damage your motherboard, the CPU, and everything plugged into it (expensive graphic card, perhaps?). If you've gotten a power supply made by someone you've never heard of, you might want to find a local hobbyist (or perhaps better a HAM radio operator) who can test the supply for you. \n\nPC Power and Cooling have a sterling reputation for the quality and reliabilty of their power supplies. Antec is also well thought of. Neither costs so much as to justify the risk of frying several hundred dollars of CPU, graphics card, motherboard, etc. \n\nSAFETY NOTE: These power supplies have lethal voltages inside. They are NOT safe to open, unless you know EXACTLY what you're doing, and even then they're dangerous as all get out. Furthermore, those lethal voltages will still be present for more than a few minutes after power is removed. Also note that many modern ATX and compatible machiens DO NOT turn off the power supply even when the front panel "power switch" is pushed and the computer shuts down. Most of the time they remain in 'warm' mode when apparently "off", and are still operating even when the computer itself isn't. Stay out of power supply innards! The only certain way to be sure the power supply is completely off (though it will remain dangerous for many minutes) is to remove the power cable. Putting it in a drawer, and closing the drawer, before doing anything further is quite sensible.

There is obviously a short circuit somewhere inside the laptop. If it is that new, send it in for repair.

You could solder onto the positive and negative parts of the battery case 2 wires with a female AC adaptor plug.  Problem is that i have no idea what mA, voltage, wattage, ohms, etc to use there.  Check the battery and look for the electrical information, or check the manufacturer's page for some schematics.  About 3 years ago i ran an old computer that way after the battery died since i didnt feel like roaming the globe for a battery that fit.\n\nYour safest bet is the battery and if it died, replacements are EASY to find on the internet nowadays.

uhmmm.nope... not really.. but someone out there does.. i've an NEC too.. and everytym i want to know what parts are compatible on my laptop i turn to www.sparesweb.com... it's a really helpful site..check it out and it might solve ur questions..

You will need to open the case if it is not written on the back of the PSU.  That information is not shared to the computer.  You can check on the manufacturers site but, since Dell is a multi-vendor supplier, your computer and someone else's computer of the same name will not necessarily have the same power supply.  You will not need to do any serious dissembling of your case in order to read the sticker that states what it is.  Just remove the side panel or open the clam shell and it should be visible.  If you have trouble reading it all but can get the product ID number then you can search for its specs online.\n\nMost power supplies are very similar in size (woot stanadards) but it could be an unusual size.  It will be written on the sticker along with what it is rated for.  If you are looking for a replacement or wondering if a system problem is related to your power supply you WILL need to look.  Power supplies are often the first piece of hardware to fail on a computer and adding additional hard drives, cd/dvd drives, memory, or a faster processor will increase the required available power.  Computer manufacturers usually use the bare minimum power supply they can.  You can pretty much pick out a good power supply by its rated wattage and it weight.  A good power supply will be heavier.\n\nSo the short answer is no.  If you have a specific problem related to the power supply post another question.\n\nHope this helps and GL :-)

I think they have different power connectors, for different types of motherboards.

Hi,\n\nHere is a pic with many laptop connections.\nAll are named on the pic.

Verify it is ON in the BIOS.

There should be a power connection. If not, ask your vendor. Otherwise, for installation, visit here:

You may try www.ebay.com in the search box put in "Laptop Power Supply" from that page you keep refining until ya get what you want or you can try "Want it Now" but the price will be higher!

Check whether the power cables from the motherbaord to the powerswitch are connected properly. It could behave mad if the connection is not proper !!!!

No, it is a balance. You Match the power supply output with the load requirements of all the components. Most have reserve capacity.\n\nWhen you upgrade your computer with more hard drives, more powerfull video or sound cards then you need a more powerfull power supply
