(E6220) Is this laptop work with the Dell 130W adapter?

I picked up a no webcam Latitude E6220 (gov’t surplus) for a really agreeable price, but I do not get a hard drive, caddy or interposer since it was government surplus. As such, I also do not get a power adapter, but it was tested to boot so I know the laptop is ready to go once I get a drive and caddy/interposer. It came with the backlit keyboard from the factory so no need to upgrade that :-)

The catch is I do not own a Dell 90W adapter, which is the officially supported maximum adapter Dell sells for it. The adapter I have available that’s the least wasteful is a 130W 0VJCH5 (reliable revision) from my old E6540 with GPU issues - I have a 180W 0WW4XY I got as a depot error (and was allowed to keep it, which I have in my eMails in writing) but I am saving that one for a more appropriate system. It isn't very portable and nearly dwarfs the 6220 itself since the adapter is 7” long and the laptop is 12”… Not a good travel adapter.

Can I use the 130W adapter temporarily until I get a 90W adapter or will it fry the system board? You can get away with 65->90 (+25W) comfortably, but 90->130 (+40) is quite a jump.

Hi Nick!

Yes it should work. Sometimes I use a docking station power adapter on the laptop it’s self. The original adapter is 90 Watt, the docking station adapter is also 130 Watt.

The most important thing is, the voltage. If the voltage is higher then it should get you could fry something. Not if it’s a very tiny difference 19V - 19,5V, but still I don’t recommend to use it. If it’s a huge difference in voltage, you’ll fry something for sure…

At my case, the voltage is equal of the original adapter, so it should be good (also a Dell laptop).

Which model do you have? I know for the 6220 I seen a 65W on the support page. What I'm thinking is the base i5 systems ship with 65W (battery supplement) but are 90W upgradeable (CTO or post purchase) and the i7 gets the 90W (mandatory). I'm suspecting it'll throttle without a battery if I get the 65W adapter.

The problem with small wattage adapters like the 65W on a class of laptop like this is that assumes you have a battery - which is why I want a 90W if I need to start from ground zero drive and adapter wise. From the photos, it looks like a 19.5V system and my adapter I set aside for it is also 19.5V as well. Dell seems to standardize on 19.5V with their laptops.

The old X Series ThinkPads have the same issue - the 65W throttles without a battery, but that's gone with a 90W. It's the main reason if I get a X60-230, I'll buy a 90W adapter although I think the Core i ones fixed that(X201-230). I'm not changing that rule because this says Dell and not Lenovo.

I have better info on it. It's a 65W minimum laptop - but it's 90/130/180/240W compatible.

The Latitude 5480 is the model I got. The i5 ships with 65W adapters indeed, the i7 with an 90W. It won't hurt to buy a 90W adapter instead of the 65W. I'm glad that it's all working for you now :).

@koppie007 On the i5 Dell laptops, I believe the benefit isn't eliminated throttling like Lenovos of the past. I think it's more to do with charge speed on the i5 version - which is what I bought. BUT I wouldn't put it past Dell on a E62 machine with a 65W adapter without the battery or with the wrong one (3 cell). It's sometimes a necessity on these small laptops. It doesn't tend to be an issue on the 14" class, but the 11-12" class is prone to it. Some 13" class machines may throttle without a battery too, but it's less of an issue. I believe it has to do with how most of them share power delivery due to the compact size.

I wish the i7's were more common, but most of them seem to come with the 2520M i5. You're also not going to find them for what I paid either to be fair (3-4% of the original ~$1.5-2k sticker price).

It turns out it was cheaper to buy a cosmetically troubled E6220 with a genuine 90W and 2 batteries to complete my nice surplus one since I needed both parts.

Hi @nick ,

FYI with power output figures they never change the supply voltage as all the components are designed to work at the specified voltage.

What does change is the current being supplied.

Power equals voltage times current (P=E x I).

The higher output power adapter regulates its' current output , whilst maintaining the correct voltage output, to match the demands of the laptop at any given point in time e.g high cpu usage fan rpm increases more current required which will be supplied by the charger, when cpu usage decreases and fan throttles back current supply is reduced

The adapter will only supply what the laptop wants at the time, not any more. This includes keeping the battery charged.

For example a higher output power charger can supply a high demand load and keep the battery charged where a lower output power charger may only be able to supply the high demand load and the battery may be only being maintained at its present state of charge or it may even be discharging helping to supply the load. It may depend on how power distribution is configured in the power management of the laptop.

@jayeff I didn't want to fry my new laptop with how much of a jump it is. I was also worried about the BIOS rejecting it, but I may be in the clear there since Dell lists the 130W on the adapter page - but that may be for the dock. What I'm hoping for is the 130W adapter is registered at 90W as far as the BIOS is concerned so I'm clear.

It didn't come with a battery so I probably need a higher wattage adapter to compensate despite getting an i5 version. I suspect it's like the older ThinkPad X Series systems where it supplements the 65W adapter with battery power on i5 systems and REQUIRES the 90W on the i7 models.

I know I could have gotten an HP Stream 11 type laptop for a small knockaround computer that doesn't need work, but I do not like the lack of upgradeability, low eMMC capacity and Celeron processors.
