CPU upgrade for Dell 1545 Inspiron

Laptop CPU upgrades aren't like desktop upgrades, they're far more...uh...problematic. You *might* be able to get a T9500 in there, but you'll have to hunt down a service manual for your motherboard to make sure. And that's assuming you can track one down at a cost at which this makes sense. It's a very, very old laptop.

The Dell Inspiron 1545 can accept up to a Intel Core 2 Duo T9900.

Here is a list of possible cpu upgrades for the Dell Inspiron 1545. I have also included some recent Ebay buy it now prices for used cpu's to give an idea of the current used prices.

no matter the chipset or bios?

this is correct???

Yes, it will work fine. You might want to check with Dell to see if there's a BIOS upgrade available first, but I'm pretty sure any BIOS revision will take any chip. All 1545's are supported up to the T9900. It will unquestionably work. I actually got ahold of a T9900 and installed it a few months ago.

All you need is a small screwdriver to remove and then put back the heatsink and some new thermal paste to put on the new CPU once you've installed it. You can do it in 10 minutes.

great. thanks for the reply.

I spoke to Dell Tech Support today and they tell me the 1545 can only support up to a T6600. I believe they say this because that the highest CPU they have in inventory but wanted to ask if anyone has had issues with T7xxx, T8xxx or T9xxx CPU's. What do you have to change in the BIOS to ensure the MB recognizes the upgrade. Any concerns on overheating?

Which motherboard is in your 1545? I have a 1537 with a 0P173H mobo running a T5800 and am not sure what CPU I can upgrade to. Any advice is appreciated. Thanks

Thanks for the info. Just ordered a t9600 from Amazon. I have done a lot of research on this. I am not cheap, I am just trying to improve the performance on this used 1545. It actually runs extremely fine with the t4200, I have had to replace the hdd with another found unit, Installed Linux and it is fine. I have firefox open, 8 tabs, listening to music on VLC, system tray monitor running, 4 gbs of ram, I amusing 1gb, t4200 is humming along nicely at 54 degrees centigrade, I am just curious how much more I can tweak for my modest use. Thanks again. I am 62 years old, electronic tech, tubes to solid state, b&w crt to flat screen, love tinkering with electronics. I had an old Desktop 2000, manufactured in 1997 it would not handle broadband, it was, I think, 160ghz. There was a dipswitch on the motherboard that allowed me to bump it up to 240. I used that as a backup, upgraded it to winxp, was told that was not possible, I had to upgrade the bios via floppy disks. laid off and broke, I used that for years. Obviously, just basic usage, lol, you tube was lag tube. Wrong advice told me it was not possible, Proper advice told me it was.
