Socketed CPUs swap. BGA chips don’t. We tell you which path your laptop has — free diagnosis ₹149.
Most modern laptops have BGA-soldered CPUs bonded directly to the motherboard — upgrading them requires specialist micro-soldering, not a simple socket swap. But socketed laptops do exist: ThinkPad T-series, HP EliteBook G-series, and Dell Latitude E-series from 2011–2017 can absolutely swap CPUs. More importantly, 90% of “my laptop is slow” calls are solved by RAM, SSD, or thermal repaste — not CPU. We bench-test, give you an honest verdict in 30 minutes, ₹149.
Your laptop falls into one of three categories. We identify which one and give you the honest options.
ThinkPad T-series (T420, T430, T440p), HP EliteBook 8460p/8470p/8560p/8570p, Dell Latitude E6420/E6430/E6440 — these use rPGA988B, PGA947, or FCPGA1023 sockets. CPU upgrade is genuine: pull the old chip, seat a higher-tier same-generation chip, apply fresh thermal compound. Example: T420 i5-2520M (2 cores) → i7-2820QM (4 cores, 8 threads) = 60–80% multithread uplift. Clevo / Sager mobile workstations also typically socketed.
₹3,500 labour + chip cost · 1-day turnaroundMost laptops from 2017 onward use BGA (Ball Grid Array) CPUs soldered directly to the PCB. A CPU swap here means: desolder the existing BGA package under infrared heat, clean pads, reball the replacement chip with solder balls, reflow-solder onto the board. The replacement must be the same BGA package size and chipset-compatible — e.g., i5-8250U to i7-8550U (both BGA1356). We have an infrared rework station on-bench. Turnaround 7–10 days.
₹15,000–₹25,000 labour + ₹4,000–₹12,000 chip90% of customers who come asking “can I upgrade the CPU?” are actually dealing with: a spinning HDD throttling boot and load times, 4GB or 8GB RAM causing swap thrash with Chrome + one app, or a degraded thermal compound making the CPU throttle down under load. A RAM upgrade + SSD upgrade on a 5-year-old laptop feels faster than a CPU upgrade on the same hardware. We diagnose first and propose what actually moves the needle.
₹800–₹6,000 depending on path · Same-day possibleThree diagnostic questions we ask before any quote. You can self-screen here first.
ThinkPad X1 Carbon, Dell XPS 13/15, HP Spectre, Asus ZenBook, Lenovo IdeaPad 5 — these are almost certainly BGA-soldered. CPU upgrade is not realistic. We focus diagnostic attention on: RAM expansion (if slots exist), NVMe SSD upgrade, thermal repaste, and battery replacement to eliminate throttling on AC power. These alone can halve load times and extend the laptop's useful life by 3–4 years.
ThinkPad T420/T430/T440/T440p/T450, HP EliteBook 8x60/8x70, Dell Latitude E-series, Lenovo W-series workstations, MSI and Clevo gaming chassis from this era — these likely have a socketed CPU. We open the bottom panel and visually confirm the socket before any quote. If socketed, you get full upgrade path discussion: which higher-tier CPU the chipset supports, DDR3/DDR3L RAM ceiling, BIOS compatibility.
ASUS ROG, MSI Raider, Acer Predator, HP Omen — almost all BGA-soldered, even the ones with 45W TDP processors. The CPU upgrade path is rarely worth pursuing. What does work: repasting with Honeywell PTM7950 or Thermal Grizzly Kryonaut Extreme (high-TDP gaming chips run 95°C+; good paste = 10–15°C drop + longer turbo holds), GPU core undervolting, and increasing fan curve via software. Combined these give a genuine 10–20% sustained performance uplift.
For laptops where CPU swap isn’t possible or cost-effective, these three paths deliver real, measurable uplift.
Moving from a spinning HDD to an NVMe Gen 3 or Gen 4 SSD cuts boot time from 70–90 seconds to 10–14 seconds. Sequential reads jump from 100 MB/s to 3,500–7,000 MB/s. Real-world: a ThinkPad T480 with original HDD boots in 90 seconds and takes 40 seconds to open Chrome + 3 tabs. After 1TB Samsung 980 Pro NVMe: 12-second boot, Chrome opens in 3 seconds. The CPU didn’t change. The experience completely changed. SATA SSD to NVMe upgrade gives a further 2–3× jump on sustained read/write.
₹2,500–₹8,000 depending on capacity4GB RAM in 2026 means Chrome + one app triggers swap to disk, making everything feel frozen. 8GB is the floor; 16GB is comfortable; 32GB is future-proof for DDR4 systems. DDR5 systems (12th gen Intel and AMD Ryzen 6000+) benefit from 32GB+ for creative and developer workflows. Dual-channel matters: two 8GB sticks outperform one 16GB stick by 15–20% in bandwidth-sensitive tasks. We verify your laptop’s maximum supported RAM and DDR generation before sourcing.
₹1,200–₹4,500 for 8–32GB upgradeLaptop thermal paste dries out and cracks over 3–5 years. When that happens, the CPU hits 95–100°C within 30 seconds of load and throttles down to 60–70% of rated speed — the chip is protecting itself. Replacing the compound with Thermal Grizzly Kryonaut or Honeywell PTM7950 (a phase-change material, excellent for BGA packages) drops CPU temps 10–18°C and lets the chip hold full turbo clock speeds through sustained loads. We also replace thermal pads on the VRM and GPU die where applicable.
₹800–₹1,800 parts + labour₹149 bench diagnosis before any upgrade recommendation. We open, confirm socket type, check RAM slots and SSD bay, test battery health, and give you the honest options — not the most expensive ones.
Our infrared rework station handles BGA CPU reballing in-house. No outsourcing, no guessing. Chip sourcing verified against BGA package and chipset support before we quote the job.
Thermal repaste + pad replacement + fan curve calibration performed together, not in isolation. We monitor CPU temps under load post-service to confirm the improvement before returning the laptop.
Hyderabad’s longest-running laptop service centre. We’ve handled socketed CPU swaps on every major ThinkPad generation, BGA reballs on ultrabooks, and thousands of RAM + SSD upgrades.
Mostly no on modern laptops made after 2017. Most ultrabooks and thin-and-light laptops use BGA-soldered CPUs that are permanently bonded to the motherboard — swapping them requires advanced micro-soldering (BGA reflow), not a simple socket swap. However, business laptops from 2011–2017 — ThinkPad T-series, HP EliteBook G-series, Dell Latitude E-series — often use socketed CPUs (rPGA988B, PGA947, FCPGA1023) that can be upgraded just like a desktop chip.
Tell-tale signs: if it’s a 2011–2017 ThinkPad T-series (T420, T430, T440p, T450), HP EliteBook 8x60/8x70, or Dell Latitude E-series, there’s a good chance it’s socketed. Ultrabooks (ThinkPad X1 Carbon, HP Spectre, Dell XPS), gaming laptops, and almost everything made after 2017 are BGA-soldered. We open the bottom panel and confirm for you — it’s covered in the ₹149 diagnosis fee. No guesswork, no spec-sheet reading — visual confirmation on the board.
T420 (Sandy Bridge, rPGA988B socket): upgrade from i5-2520M (2 cores, 4 threads) to i7-2820QM (4 cores, 8 threads) — roughly 60–80% multithread uplift. T430 (Ivy Bridge): supports up to i7-3940XM quad-core — significant jump from any i5 dual-core. T440p (Haswell, the best socketed ThinkPad for upgrading): supports i7-4940MX quad-core, plus DDR3L slots support up to 16GB, and the HDD bay accepts an NVMe adapter. Labour ₹3,500 + chip cost. 1-day turnaround.
BGA reball runs ₹15,000–₹25,000 in labour (infrared rework station time, stencil, reballing materials, post-reflow testing) plus ₹4,000–₹12,000 for the replacement chip. It’s only worth pursuing on premium laptops where the motherboard replacement cost exceeds ₹40,000. The replacement chip must be from the same BGA package family and supported by the existing chipset — e.g., i5-8250U to i7-8550U within the same Whiskey Lake BGA1356 package. Turnaround is 7–10 days. We verify compatibility before accepting the job.
In order of impact: (1) SSD upgrade — replacing a spinning HDD with an NVMe SSD cuts boot time from 90 seconds to 12 seconds and makes every file operation feel instant; (2) RAM upgrade — going from 4GB or 8GB to 16GB or 32GB eliminates swap thrash in Chrome, IDEs, and multitasking; (3) thermal repaste — a degraded thermal compound causes CPU throttling under load; replacing it with Thermal Grizzly or Honeywell PTM7950 recovers the CPU’s full turbo speed; (4) clean OS reinstall — removes bloatware and gives 20–30% perceived speedup; (5) battery replacement — a degraded battery triggers CPU power limiting even on AC power on some models.
Yes — we use ThrottleStop (Intel) and AMD’s built-in undervolting tools on supported chips. Typical results: 8–12°C cooler under sustained load, longer turbo boost holds, and 20–40 minutes extra battery life per charge cycle. We apply undervolting as a free add-on with any thermal service or RAM/SSD upgrade. Note: Intel patched Plundervolt-era undervolting on 10th gen and later via BIOS lock, so deep negative voltage offsets on newer Intel chips may be limited. We assess support before applying.
No. Intel MacBooks from 2018 onward (T2 chip era) use BGA-soldered CPUs and the T2 security coprocessor means even the BGA reball path is non-viable. Apple Silicon MacBooks (M1/M2/M3/M4) have the CPU, GPU, RAM, and neural engine integrated into a single SoC — they are fundamentally non-upgradeable at a component level. What we can help with: external Thunderbolt SSD for storage expansion, thermal paste replacement on older Intel MacBooks (2017 and earlier) to recover throttle performance, and deep cleaning for overheating MacBooks.
