Dell d610--battery will not charge

We have isolated the problem component ( chip) it is an 8 pin surface mount that is near the battery
the problem now is that there are no markings on the chip to indicate what it is--no manufacturer or part number
we believe it to be a mosfet--but which one ???
we believe that it turns the charging circuit on/off to the battery
the only marking on it is 4805
would appreciate if you could provide a part number

oh--and by the way wolrdvet @ fixya refered me to you--and sends his regards
thks in advance jerry

I had the same problem on D610, it was not charging the battery and also the CPU speed was showing only the minimum 800Mhz though maximum was 2Ghz. I updated the bios (though it had the newest version) and ran intel chipset driver for D610. Viola! it set the speed to 2Ghz and the battery started charging. Was it a miracle or a solution I dont know!!!

Hi mate, The trouble with SMD devices is the restrictive size and where to put ID marks. They generally only have enough to be sure that the correct feeder is loaded with the right part in manufacture. You need to get a hold of a circuit for the board with a parts list to ID the part correctly.
I did find this when I went searching for you. It looks like something you would find in the remote boot side of the network controller however. If it is an 8 pin DIP, without a heatsink then it may used to switch the power supply to the laptop for remote bootup from the network.

Computer dell latitude D610 built in 2006 replacing the viedo card how too's and also what can I do to mabe upgrade this veido card? and dose anything else need to be updated at the same time as the...


Sorry Jimmy, the Dell Latitude D610 Notebook PC uses Integrated Graphics.
There is no graphics card to upgrade.

Your Dell either came with a form of the Intel GMA graphics chipset , or the ATI Radeon Mobility X300 graphics chipset.

http://support.dell.com/support/edocs/systems/latd610/en/ug_en/specs.htm

Either/Or

The way Dell states it, (And also this is for a LOT of laptop manufacturers), is that you have either the option when purchasing, of having an Intel GMA chipset for graphics, or discrete graphics of the ATI Radeon Mobility X300, for graphics.

Discrete being the word that fools people. Makes them think it has a dedicated, removable graphics card, when in reality it is a graphics chipset soldered directly to the motherboard, and is not upgradeable.

Primer:
GPU
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

Essentially the 'graphics engine'.

A GPU can be installed directly on the motherboard, (Integrated Graphics), OR installed on a removable graphics adapter card. (Graphics Card is shortened for graphics adapter card)

Integrated Graphics borrows from the system resources. The Processor and Ram Memory.
This is why programs, for example games, that use a lot of graphics 'power', do not perform well on a computer with Integrated Graphics.

{Read - programs that use a lot of graphics power. Such as some of the newer games. Integrated graphics, depending on what graphics chipset it is, CAN run some games. Ones that are not very graphics intensive}

A dedicated graphics card has it's own processor, and graphics ram memory. Does not need to borrow from the system resources.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The graphics chipset in your Dell Latitude, is mounted to the motherboard with a BGA surface mount.
Ball Grid Array

http://en.wikipedia.org/wiki/Ball_grid_array

To explain the BGA surface mount;
Let's use the older Intel Pentium 4 processor that uses a Socket 478 processor socket.
The bottom of the processor has contact pins. (478 of 'em)
The processor socket has matching socket holes for the contact pins. (478 of 'em)

With the BGA surface mount there are no contact pins. In place of them are Solder Balls.
There is no socket, or socket holes on the motherboard.
There are Copper Pads.

The graphics chipset is set into place with the Solder Balls lining up on the motherboard's Copper Pads.
Then heat is applied at a specified temperature, and length of time.

The solder balls melt which solders the graphics chipset to the motherboard. (To the Copper Pads)

Removal and replacement is properly performed with a BGA Rework Machine.
Costly, and not something you'll find a local shop performing.
{The machine is costly, and the operator needs to be S-K-I-L-L-E-D. Cost of having a chipset replaced is Ouch!}

There are two ways you can upgrade your graphics.

1) If you have the motherboard model with a form of Intel GMA chipset attached, you can purchase the motherboard that has the ATI Radeon Mobility X300, and install it.

2) Purchase a laptop with better graphics.

{Not trying to be snide}

LIGHT COMES ON AC ADAPTER BUT GOES OFF WHEN PLUGGED INTO NOTEBOOK


This is possibly an internal power Supply fault. take the battery out, plug in the adapter, IF the unit works now, you have A: A battery problem, or B: a charging circuit problem. If the unit still fails to work, the power supply in the PC has faulted. You need to get a "Quote: for a repair.

Fan wont turn on infocus x2, instead makes funny siren noise and attempts to turn. Small fan inside works fine, larger one cant but will turn if touched, so doesn't seem to be anything in the way of it.


This problem is almost never the actual fan itself failing..
The intermittent whine you hear is the result of the Mos-Fet fan driver chip which is the speed control current amplifier.
It's an 8 pin surface mount chip on the bottom of the main (lower) circuit board. This is a common failure with these projectors.
The chip is inexpensive and needs to be replaced by someone who is skilled in surface mount component technology. You can replace the fan but you will still have the same problem. Hint, the bad chip is not the one closest to the large fan connector... It's the one closest to the small fan connector and it will measure 45-60 ohm's between pins 7 and 8. the part (rns70d) is discontinued however there is a replacement that can be purchased at...

Dell d610 latitude wont charge new battery


Hey,
First off, do you have a way to check the output of the ac adapter to ensure it's putting out the correct current?
If you've done that and have a multimeter handy, you can remove the battery, system off, and check the charge pins for current/voltage. I believe one of the end pins is neg (ground) and at least one of the other pins should show 2.6-3.6V, as well as other various voltages. If you fail to get any response at the charger pins, we'll need to look at the board circuitry, assuming again that the ac adapter is operating properly.
Good luck

Dell latidue D610


The light indicator for the battery is; green-charging, yellow-battery failure, and red-charging system failure. The charging system failure happens when the power management chip fails. The pm chip regulates and controls the power input & usage, allows the machine to switch from AC to battery, and cotrols the charging. This will also cause the problem with the power button not workin or being hard to start. Unfortunately, the motherboard will have to be replaced in order to fix this.

Battery does not charge


Take the chip out and try Radio Shack, they have a large selection of various computer chips, circuits,etc... If they don't have it in stock they have many electronics catalogs and should be able to order it for you. Your other option is contacting Dell, or getting a perts board off Ebay.

Dell D610 charging problem


Does it run without the battery installed? Also, will it run only off the battery? Isolate those two conditions, then we'll be able to narrow down the problem.
